+                  System Dependend Drive Permission Examples
+
+Accessing the optical drives requires privileges which usually are granted
+only to the superuser. Linux, FreeBSD, Solaris, NetBSD, offer quite different
+approaches for avoiding the need for unrestricted privileges.
+
+First check whether some friendly system setting already allows you to
+access the drives as normal user:
+  cdrskin --devices
+Those drives of which you see address and type strings are already usable.
+
+If there remain drives invisible which the superuser can see by the same
+command, then the following examples might help:
+
+--------------- 
+On all systems:
+--------------- 
+Add the authorized users of CD drives to group "floppy" in /etc/group.
+If missing: create this group.
+Changes to /etc/group often only affect new login sessions. So log out and in
+before making the first tests.
+
+---------
+On Linux:
+---------
+Allow rw-access to the drives
+  chgrp floppy /dev/sr0 /dev/sr1
+  chmod g+rw   /dev/sr0 /dev/sr1
+It might be necessary to perform chgrp and chmod after each reboot or to
+edit distro dependent device configuration files for permanent settings.
+
+-----------
+On FreeBSD:
+-----------
+Edit /etc/devfs.rules and make sure to have these lines
+  [localrules=10]
+  add path 'acd*' mode 0664 group floppy
+  add path 'cd*' mode 0664 group floppy
+  add path 'pass*' mode 0664 group floppy
+  add path 'xpt*' mode 0664 group floppy
+  [localrules=5]
+  add path 'pass*' mode 0664 group floppy
+  add path 'cd*' mode 0664 group floppy
+  add path 'xpt*' mode 0664 group floppy
+  add path 'acd*' mode 0664 group floppy
+
+Edit /etc/rc.conf and add the following line if missing
+  devfs_system_ruleset="localrules"
+
+This gets into effect by reboot or by command
+  /etc/rc.d/devfs start
+
+-----------
+On Solaris:
+-----------
+Run cdrskin by
+  pfexec cdrskin ...arguments...
+
+The following settings will make pfexec keep original UID and EUID and prevent
+most superuser powers. Be aware that you still can manipulate all device files
+if you have the file permissions for that.
+Full root privileges for cdrskin can then be aquired only by command su.
+
+Edit /etc/security/exec_attr and add this line to the other "Media Backup"
+lines:
+  Media Backup:solaris:cmd:::/usr/local/bin/cdrskin:privs=basic,sys_devices
+Edit /etc/user_attr and add profile "Media Backup" to the user's line:
+  thomas::::profiles=Media Backup,Primary Administrator;roles=root
+See also man privileges, man exec_attr, man user_attr.
+
+Then allow the group r-access to the drives
+  pfexec chgrp floppy /dev/rdsk/c3t0d0s2 /dev/rdsk/c4t0d0s2
+  pfexec chmod g+r    /dev/rdsk/c3t0d0s2 /dev/rdsk/c4t0d0s2
+The last two commands have to be executed after each boot. I do not know
+the relevant device configuration files yet.
+
+----------
+On NetBSD:
+----------
+Allow rw-access to the drives
+  chgrp floppy /dev/rcd[01]d
+  chmod g+rw   /dev/rcd[01]d

+CD-TEXT from the view of the user:
+
+CD-TEXT records attributes of disc and tracks on audio CD.
+
+The attributes are grouped into blocks which represent particular languages.
+Up to 8 blocks are possible.
+
+There are 13 defined attribute categories, which are called Pack Types and are
+identified by a single-byte code:
+  0x80 = Title
+  0x81 = Names of Performers
+  0x82 = Names of Songwriters 
+  0x83 = Names of Composers
+  0x84 = Names of Arrangers 
+  0x85 = Messages
+  0x86 = text-and-binary: Disc Identification
+  0x87 = text-and-binary: Genre Identification
+  0x88 = binary: Table of Content information
+  0x89 = binary: Second Table of Content information
+  (0x8a to 0x8c are reserved.)
+  0x8d = Closed Information
+  0x8e = UPC/EAN code of the album and ISRC code of each track
+  0x8f = binary: Size Information of the Block
+
+Some of these categories apply to the whole disc only:
+  0x86, 0x87, 0x88, 0x89, 0x8d
+Some have to be additionally attributed to each track, if they are present for
+the whole disc:
+  0x80, 0x81, 0x82, 0x83, 0x84, 0x85, 0x8e  
+One describes the overall content of a block and in part of all other blocks:
+  0x8f
+
+The total size of a block's attribute set is restricted by the fact that it
+has to be stored in at most 253 records with 12 bytes of payload. These records
+are called Text Packs.
+A shortcut for repeated identical track texts is provided, so that a text
+that is identical to the one of the previous track occupies only 2 or 4 bytes.
+
+
+-------------------------------------------------------------------------------
+Content specification of particular pack types:
+
+Pack types 0x80 to 0x85 and 0x8e contain 0-terminated cleartext. If double byte
+characters are used, then two 0-bytes terminate the cleartext.
+The meaning of 0x80 to 0x85 should be clear by above list. They are encoded
+according to the Character Code of their block. Either as ISO-8859-1 single
+byte characters, or as 7-bit ASCII single byte characters, or as MS-JIS double
+byte characters.
+More info to 0x8e is given below.
+
+Pack type 0x86 (Disc Identification) is documented by Sony as "Catalog Number:
+(use ASCII Code) Catalog Number of the album". So it is not really binary
+but might be non-printable, and should contain only bytes with bit7 = 0.
+
+Pack type 0x87 contains 2 binary bytes, followed by 0-terminated cleartext.
+The two binary bytes form a big-endian index to the following list.
+  0x0000 = "Not Used" (Sony prescribes to use this if no genre applies)
+  0x0001 = "Not Defined"
+  0x0002 = "Adult Contemporary"
+  0x0003 = "Alternative Rock"
+  0x0004 = "Childrens Music"
+  0x0005 = "Classical"
+  0x0006 = "Contemporary Christian"
+  0x0007 = "Country"
+  0x0008 = "Dance"
+  0x0009 = "Easy Listening"
+  0x000a = "Erotic"
+  0x000b = "Folk"
+  0x000c = "Gospel"
+  0x000d = "Hip Hop"
+  0x000e = "Jazz"
+  0x000f = "Latin"
+  0x0010 = "Musical"
+  0x0011 = "New Age"
+  0x0012 = "Opera"
+  0x0013 = "Operetta"
+  0x0014 = "Pop Music"
+  0x0015 = "Rap"
+  0x0016 = "Reggae"
+  0x0017 = "Rock Music"
+  0x0018 = "Rhythm & Blues"
+  0x0019 = "Sound Effects"
+  0x001a = "Spoken Word"
+  0x001b = "World Music"
+Sony documents the cleartext part as "Genre information that would supplement
+the Genre Code, such as 'USA Rock music in the 60s'". Always ASCII encoded.
+
+Pack type 0x88 records information from the CD's Table of Content, as of
+READ PMA/TOC/ATIP Format 0010b (mmc3r10g.pdf, table 237 TOC Track Descriptor
+Format, Q Sub-channel).
+See below, Format of a CD-TEXT packs array, for more details about the content
+of pack type 0x88.
+
+Pack type 0x89 is yet quite unclear. It might be a representation of Playback
+Skip Interval, Mode-5 Q sub-channel, POINT 01 to 40 (mmc3r10g.pdf 4.2.3.6.3).
+If so, then this seems not to apply to write type SAO, because the CUE SHEET
+format offers no way to express Mode-5 Q.
+See below, Format of a CD-TEXT packs array, for an example of this pack type.
+
+Pack type 0x8d is documented by Sony as "Closed Information: (use 8859-1 Code)
+Any information can be recorded on disc as memorandum. Information in this
+field will not be read by CD TEXT players available to the public."
+Always ISO-8859-1 encoded.
+
+Pack type 0x8e is documented by Sony as "UPC/EAN Code (POS Code) of the album.
+This field typically consists of 13 characters." Always ASCII encoded.
+It applies to tracks as "ISRC code [which] typically consists of 12 characters"
+and is always ISO-8859-1 encoded.
+MMC calls these information entities Media Catalog Number and ISRC.
+The catalog number consists of 13 decimal digits.
+ISRC consists of 12 characters: 2 country code [0-9A-Z], 3 owner code [0-9A-Z],
+2 year digits (00 to 99), 5 serial number digits (00000 to 99999).
+
+Pack type 0x8f summarizes the whole list of text packs of a block.
+See below, Format of a CD-TEXT packs array, for details.
+
+
+-------------------------------------------------------------------------------
+Format of a CD-TEXT packs array:
+
+The attributes are represented on CD as Text Packs in the sub-channel of
+the Lead-in of the disc. See doc/cookbook.txt for a description how to write
+the readily formatted CD-TEXT pack array to CD, and how to read CD-TEXT packs
+from CD.
+
+The format is explained in part in MMC-3 (mmc3r10g.pdf, Annex J) and in part by
+the documentation in Sony's cdtext.zip :
+
+Each pack consists of a 4-byte header, 12 bytes of payload, and 2 bytes of CRC.
+
+The first byte of each pack tells the pack type. See above for a list of types.
+
+The second byte tells the track number to which the first text piece in
+a pack is associated. Number 0 means the whole album. Higher numbers are
+valid for types 0x80 to 0x85, and 0x8e. With these types, there should be
+one text for the disc and one for each track.
+With types 0x88 and 0x89, the second byte bears a track number, too.
+With type 0x8f, the second byte counts the record parts from 0 to 2.
+
+The third byte is a sequential counter.
+
+The fourth byte is the Block Number and Character Position Indicator.
+It consists of three bit fields:
+  bit7   = Double Bytes Character Code (0= single byte characters)
+  bit4-6 = Block Number (groups text packs in language blocks)
+  bit0-3 = Character position. Either the number of characters which
+           the current text inherited from the previous pack, or
+           15 if the current text started before the previous pack.
+
+The 12 payload bytes contain pieces of 0-terminated texts or binary data.
+A text may span over several packs. Unused characters in a pack are used for
+the next text of the same pack type. If no text of the same type follows,
+then the remaining text bytes are set to 0.
+
+The CRC algorithm uses divisor 0x11021. The resulting 16-bit residue of the
+polynomial division gets inverted and written as big-endian number to bytes
+16 and 17 of the pack. 
+
+
+The text packs are grouped in up to 8 blocks of at most 256 packs. Each block
+is in charge for one language. Sequence numbers of each block are counted
+separately. All packs of block 0 come before the packs of block 1.
+
+The limitation of block number and sequence numbers imply that there are at
+most 2048 text packs possible. (READ TOC/PMA/ATIP could retrieve 3640 packs,
+as it is limited to 64 kB - 2.)
+
+
+If a text of a track (pack types 0x80 to 0x85 and 0x8e) repeats identically
+for the next track, then it may be represented by a TAB character (ASCII 9)
+for single byte texts, resp. two TAB characters for double byte texts.
+(This should be used because 256 * 12 bytes is few space for 99 tracks.)
+
+The two binary bytes of pack type 0x87 are written to the first 0x87 pack of
+a block. They may or may not be repeated at the start of the follow-up packs
+of type 0x87.
+
+The first pack of type 0x88 in a block records in its payload bytes:
+   0 : PMIN of POINT A1 = First Track Number
+   1 : PMIN of POINT A2 = Last Track Number
+   2 : unknown, 0 in Sony example
+   3 : PMIN of POINT A2 = Start position of Lead-Out
+   4 : PSEC of POINT A2 = Start position of Lead-Out
+   5 : PFRAME of POINT A2 = Start position of Lead-Out
+   6 to 11 : unknown, 0 in Sony example
+The following packs record PMIN, PSEC, PFRAME of the POINTs between the
+lowest track number (min 01h) and the highest track number (max 63h).
+The payload of the last pack is padded by 0s.
+The Sony .TOC example:
+  A0 01
+  A1 14
+  A2 63:02:18
+  01 00:02:00
+  02 04:11:25
+  03 08:02:50
+  04 11:47:62
+  ...
+  13 53:24:25
+  14 57:03:25
+yields
+  88 00 23 00 01 0e 00 3f 02 12 00 00 00 00 00 00 12 00
+  88 01 24 00 00 02 00 04 0b 19 08 02 32 0b 2f 3e 67 2d
+  ...
+  88 0d 27 00 35 18 19 39 03 19 00 00 00 00 00 00 ea af
+
+Pack type 0x89 is yet quite unclear. Especially what the information shall
+mean to the user of the CD. The time points in the Sony example are in the
+time range of the tracks numbers that are given before the time points:
+  01 02:41:48 01 02:52:58
+  06 23:14:25 06 23:29:60
+  07 28:30:39 07 28:42:30
+  13 55:13:26 13 55:31:50
+yields
+  89 01 28 00 01 04 00 00 00 00 02 29 30 02 34 3a f3 0c
+  89 06 29 00 02 04 00 00 00 00 17 0e 19 17 1d 3c 73 92
+  89 07 2a 00 03 04 00 00 00 00 1c 1e 27 1c 2a 1e 72 20
+  89 0d 2b 00 04 04 00 00 00 00 37 0d 1a 37 1f 32 0b 62
+The track numbers are stored in the track number byte of the packs. The two
+time points are stored in byte 6 to 11 of the payload. Byte 0 of the payload
+seems to be a sequential counter. Byte 1 always 4 ? Byte 2 to 5 always 0 ?
+
+Pack type 0x8f summarizes the whole list of text packs of a block.
+So there is one group of three 0x8f packs per block.
+Nevertheless each 0x8f group tells the highest sequence number and the
+language code of all blocks.
+The payload bytes of three 0x8f packs form a 36 byte record. The track number
+bytes of the three packs have the values 0, 1, 2.
+    Byte :
+       0 : Character code for pack types 0x80 to 0x85:
+           0x00 = ISO-8859-1
+           0x01 = 7 bit ASCII
+           0x80 = MS-JIS (japanese Kanji, double byte characters)
+       1 : Number of first track
+       2 : Number of last track
+       3 : libcdio source states: "cd-text information copyright byte"
+           Probably 3 means "copyrighted", 0 means "not copyrighted".
+  4 - 19 : Pack count of the various types 0x80 to 0x8f.
+           Byte number N tells the count of packs of type 0x80 + (N - 4).
+           I.e. the first byte in this field of 16 counts packs of type 0x80.
+ 20 - 27 : Highest sequence byte number of blocks 0 to 7.
+ 28 - 36 : Language code for blocks 0 to 7 (tech3264.pdf appendix 3)
+           Not all of these Codes have ever been seen with CD-TEXT, though.

+Overview of libburn API calls for CD-TEXT (see libburn/libburn.h for details):
+
+libburn can retrieve the array of text packs from a CD:
+
+  int burn_disc_get_leadin_text(struct burn_drive *d,
+                                unsigned char **text_packs, int *num_packs,
+                                int flag);
+
+
+It can write a text pack set with a CD SAO session.
+
+This set may be attached as array of readily formatted text packs by:
+
+  int burn_write_opts_set_leadin_text(struct burn_write_opts *opts,
+                                      unsigned char *text_packs,
+                                      int num_packs, int flag);
+
+The array of text packs may be read from a file by
+
+  int burn_cdtext_from_packfile(char *path, unsigned char **text_packs,
+                                int *num_packs, int flag);
+
+
+Alternatively the pack set may be defined by attaching CD-TEXT attributes
+to burn_session and burn_track:
+
+  int burn_session_set_cdtext_par(struct burn_session *s,
+                                  int char_codes[8], int copyrights[8],
+                                  int languages[8], int flag);
+
+  int burn_session_set_cdtext(struct burn_session *s, int block,
+                              int pack_type, char *pack_type_name,
+                              unsigned char *payload, int length, int flag);
+
+  int burn_track_set_cdtext(struct burn_track *t, int block,
+                            int pack_type, char *pack_type_name,
+                            unsigned char *payload, int length, int flag);
+
+Macros list the texts for genre and language codes:
+
+  BURN_CDTEXT_LANGUAGES_0X00
+  BURN_CDTEXT_FILLER
+  BURN_CDTEXT_LANGUAGES_0X45
+
+  BURN_CDTEXT_GENRE_LIST
+  BURN_CDTEXT_NUM_GENRES
+
+There is a reader for Sony Input Sheet Version 0.7T:
+
+  int burn_session_input_sheet_v07t(struct burn_session *session,
+                                    char *path, int block, int flag);
+
+and a writer which converts an array of text packs to such a Sony Input Sheet:
+
+  int burn_make_input_sheet_v07t(unsigned char *text_packs, int num_packs,
+                                 int start_tno, int track_count,
+                                 char **result, int *char_code, int flag);
+
+CD-TEXT can be read from a CDRWIN cue sheet file which defines the tracks
+of a session
+
+  int burn_session_by_cue_file(struct burn_session *session,
+                        char *path, int fifo_size, struct burn_source **fifo,
+                        unsigned char **text_packs, int *num_packs, int flag);
+
+
+The session and track attributes can then be converted into an array of
+text packs by:
+
+  int burn_cdtext_from_session(struct burn_session *s,
+                               unsigned char **text_packs, int *num_packs, 
+                               int flag);
+
+or they can be written as array of text packs to CD when burning begins and
+no array of pre-formatted packs was attached to the write options by
+burn_write_opts_set_leadin_text().
+
+There are calls for inspecting the attached attributes:
+
+  int burn_session_get_cdtext_par(struct burn_session *s,
+                                  int char_codes[8], int copyrights[8],
+                                  int block_languages[8], int flag);
+
+  int burn_session_get_cdtext(struct burn_session *s, int block,
+                              int pack_type, char *pack_type_name,
+                              unsigned char **payload, int *length, int flag);
+
+  int burn_track_get_cdtext(struct burn_track *t, int block,
+                            int pack_type, char *pack_type_name,
+                            unsigned char **payload, int *length, int flag);
+
+and for removing attached attributes:
+
+  int burn_session_dispose_cdtext(struct burn_session *s, int block);
+
+  int burn_track_dispose_cdtext(struct burn_track *t, int block);
+
+
+UPC/EAN and ISRC not only affect CD-TEXT but also information that is written
+along with the tracks in Q sub-channel. These can be influenced by
+burn_session_input_sheet_v07t(), burn_session_by_cue_file() and by
+
+  void burn_write_opts_set_mediacatalog(struct burn_write_opts *opts,
+                                      unsigned char mediacatalog[13]);
+
+  void burn_write_opts_set_has_mediacatalog(struct burn_write_opts *opts,
+                                          int has_mediacatalog);
+
+  void burn_track_set_isrc(struct burn_track *t, char *country, char *owner,
+                           unsigned char year, unsigned int serial);
+
+  int burn_track_set_isrc_string(struct burn_track *t, char isrc[13],

+-------------------------------------------------------------------------------
+Sony Text File Format (Input Sheet Version 0.7T):
+
+This text file format provides comprehensive means to define the text
+attributes of session and tracks for a single block. More than one
+such file has to be read to form an attribute set with multiple blocks.
+
+The information is given by text lines of the following form:
+  purpose specifier [whitespace] = [whitespace] content text
+[whitespace] is zero or more ASCII 32 (space) or ASCII 9 (tab) characters.
+The purpose specifier tells the meaning of the content text.
+Empty content text does not cause a CD-TEXT attribute to be attached.
+
+The following purpose specifiers apply to the session as a whole:
+  Specifier           =  Meaning
+  -------------------------------------------------------------------------
+  Text Code           =  Character code for pack type 0x8f
+                         "ASCII", "8859"
+  Language Code       =  One of the language names for pack type 0x8f
+  Album Title         =  Content of pack type 0x80
+  Artist Name         =  Content of pack type 0x81
+  Songwriter          =  Content of pack type 0x82
+  Composer            =  Content of pack type 0x83
+  Arranger            =  Content of pack type 0x84
+  Album Message       =  Content of pack type 0x85
+  Catalog Number      =  Content of pack type 0x86
+  Genre Code          =  One of the genre names for pack type 0x87
+  Genre Information   =  Cleartext part of pack type 0x87
+  Closed Information  =  Content of pack type 0x8d
+  UPC / EAN           =  Content of pack type 0x8e
+  Text Data Copy Protection = Copyright value for pack type 0x8f
+                              "ON" = 0x03, "OFF" = 0x00
+  First Track Number  =  The lowest track number used in the file
+  Last Track Number   =  The highest track number used in the file
+
+The following purpose specifiers apply to particular tracks:
+  Track NN Title      =  Content of pack type 0x80
+  Track NN Artist     =  Content of pack type 0x81
+  Track NN Songwriter =  Content of pack type 0x82
+  Track NN Composer   =  Content of pack type 0x83
+  Track NN Arranger   =  Content of pack type 0x84
+  Track NN Message    =  Content of pack type 0x85
+  ISRC NN             =  Content of pack type 0x8e
+
+The following purpose specifiers have no effect on CD-TEXT:
+  Remarks             =  Comments with no influence on CD-TEXT
+  Disc Information NN =  Supplementary information for use by record companies.
+                         ISO-8859-1 encoded. NN ranges from 01 to 04.
+  Input Sheet Version =  "0.7T"
+
+
+libburn peculiarties:
+
+libburn may read files of the described format by
+  burn_session_input_sheet_v07t()
+after the burn_session has been establiched and all burn_track objects have
+been added. It can convert an array of CD-TEXT packs into this format by
+  burn_make_input_sheet_v07t() 
+
+The following purpose specifiers accept byte values of the form 0xXY.
+  Text Code , Language Code , Genre Code , Text Data Copy Protection
+E.g. to indicate MS-JIS character code (of which the exact name is unknown):
+  Text Code           = 0x80
+Genre Code is settable by 0xXY or 0xXYZT or 0xXY 0xZT.
+  Genre Code          = 0x001b
+
+Purpose specifiers which have the meaning "Content of pack type 0xXY"
+may be replaced by the pack type codes.  E.g.:
+  0x80                =  Session content of pack type 0x80
+  Track 02 0x80       =  Track content of pack type 0x80 for track 2.
+Applicable are pack types 0x80 to 0x86, 0x8d, 0x8e.
+
+Text Code may be specified only once. It gets speficied to "ISO-8850-1"
+automatically as soon as content is defined which depends on the text
+encoding of the block. I.e with pack types 0x80 to 0x85.
+
+If a track attribute is set, but the corresponding session attribute is not
+defined or defined with empty text, then the session attribute gets attached
+as empty test. (Normally empty content is ignored.)
+
+
+Example cdrskin run with three tracks:
+
+  $ cdrskin dev=/dev/sr0 -v input_sheet_v07t=NIGHTCATS.TXT \

+   Also known as CRC-16-CCITT, CRC-CCITT 
+
+   Used in libburn for raw write modes in sector.c.
+   There is also disabled code in read.c which would use it.
+
+   ts B11222:
+   The same algorithm is prescribed for CD-TEXT in MMC-3 Annex J.
+   "CRC Field consists of 2 bytes. Initiator system may use these bytes
+    to check errors in the Pack. The polynomial is x^16 + x^12 + x^5 + 1.
+    All bits shall be inverted."
+   
+   libburn/cdtext.c uses a simple bit shifting function : crc_11021()
+
+
+   ts B20211:
+   Discussion why both are equivalent in respect to their result:
+
+   Both map the bits of the given bytes to a polynomial over the finite field
+   of two elements "GF(2)". If bytes 0 .. M are given, then bit n of byte m
+   is mapped to the coefficient of x exponent (n + ((M - m) * 8) + 16).
+   I.e. they translate the bits into a polynomial with the highest bit
+   becomming the coefficient of the highest power of x. Then this polynomial
+   is multiplied by (x exp 16).
+
+   The set of all such polynomials forms a commutative ring. Its addition
+   corresponds to bitwise exclusive or. Addition and subtraction are identical.
+   Multiplication with polynomials of only one single non-zero coefficient
+   corresponds to leftward bit shifting by the exponent of that coefficient.
+   The same rules apply as with elementary school arithmetics on integer
+   numbers, but with surprising results due to the finite nature of the
+   coefficient number space.
+   Note that multiplication is _not_ an iteration of addition here.
+
+   Function crc_11021() performs a division with residue by the euclidian
+   algorithm. I.e. it splits polynomial d into quotient q(d) and residue r(d)
+   in respect to the polynomial p = x exp 16 + x exp 12 + x exp 5 + x exp 0
+      d = p * q(d) + r(d)
+   where r(d) is of a polynomial degree lower than p, i.e. only x exp 15
+   or lower have non-zero coefficients.
+   The checksum crc(D) is derived by reverse mapping (r(d) * (x exp 16)).
+   I.e. by mapping the coefficient of (x exp n) to bit n of the 16 bit word
+   crc(D).
+   The function result is the bit-wise complement of crc(D).
+
+   Function crc_ccitt uses a table ccitt_table of r(d) values for the
+   polynomials d which represent the single byte values 0x00 to 0xff.
+   It computes r(d) by computing the residues of an iteratively expanded
+   polynomial. The expansion of the processed byte string A by the next byte B
+   from the input byte string happens by shifting the string 8 bits to the
+   left, and by oring B onto bits 0 to 7.
+   In the space of polynomials, the already processed polynomial "a" (image of
+   byte string A) gets expanded by polynomial b (the image of byte B) like this
+      a * X + b
+   where X is (x exp 8), i.e. the single coefficient polynomial of degree 8.
+
+   The following argumentation uses algebra with commutative, associative
+   and distributive laws.
+   Valid especially with polynomials is this rule:
+     (1):  r(a + b) = r(a) + r(b)
+   because r(a) and r(b) are of degree lower than degree(p) and
+   degree(a + b) <= max(degree(a), degree(b))
+   Further valid are:
+     (2):  r(a) = r(r(a))
+     (3):  r(p * a) = 0
+
+   The residue of this expanded polynomial can be expressed by means of the
+   residue r(a) which is known from the previous iteration step, and the
+   residue r(b) which may be looked up in ccitt_table.
+      r(a * X + b)
+    = r(p * q(a) * X + r(a) * X + p * q(b) + r(b))
+
+   Applying rule (1):
+    = r(p * q(a) * X) + r(r(a) * X) + r(p * q(b)) + r(r(b))
+
+   Rule (3) and rule (2):
+    = r(r(a) * X) + r(b)
+
+   Be h(a) and l(a) chosen so that:  r(a) = h(a) * X + l(a),
+   and l(a) has zero coefficients above (x exp 7), and h(a) * X has zero
+   coefficients below (x exp 8). (They correspond to the high and low byte
+   of the 16 bit word crc(A).)
+   So the previous statement can be written as:
+    = r(h(a) * X * X)  + r(l(a) * X) + r(b)
+
+   Since the degree of l(a) is lower than 8, the degree of l(a) * X is lower
+   than 16. Thus it cannot be divisible by p which has degree 16.
+   So: r(l(a) * X) =  l(a) * X
+   This yields
+    = l(a) * X + r(h(a) * X * X + b)
+
+   h(a) * X * X is the polynomial representation of the high byte of 16 bit
+   word crc(A).
+   So in the world of bit patterns the iteration step is:
+
+      crc(byte string A expanded by byte B)
+    = (low_byte(crc(A)) << 8) ^ crc(high_byte(crc(A)) ^ B)
+
+   And this is what function crc_ccitt() does, modulo swapping the exor
+   operants and the final bit inversion which is prescribed by ECMA-130
+   and MMC-3 Annex J.
+
+   The start value of the table driven byte shifting algorithm may be
+   different from the start value of an equivalent bit shifting algorithm.
+   This is because the final flushing by zero bits is already pre-computed
+   in the table. So the start value of the table driven algorithm must be
+   the CRC of the 0-polynomial under the start value of the bit shifting
+   algorithm.
+   This fact is not of much importance here, because the start value of
+   the bit shifter is 0x0000 which leads to CRC 0x0000 and thus to start
+   value 0x0000 with the table driven byte shifter.

+
+   Above discussion why crc_ccitt() and crc_11021() yield identical results
+   can be changed from 16 bit to 32 bit by chosing h(a) and l(a) so that:
+     r(a) = h(a) * X * X * X + l(a)
+   h(a) corresponds to the highest byte of crc(A), whereas l(a) corresponds
+   to the lower three bytes of crc(A).
+
+   This yields
+      r(a * X + b)
+    = l(a) * X + r(h(a) * X * X * X * X + b)
+
+   h(a) * X * X * X * X is the polynomial representation of the high byte of
+   32 bit word crc(A).
+   So in the world of bit patterns we have:
+
+      crc(byte string A expanded by byte B)
+    = (lowest_three_bytes(crc(A)) << 8) ^ crc(high_byte(crc(A)) ^ B)
+
+
+   Regrettably this does not yet account for the byte-internal mirroring of
+   bits during the conversion from bit pattern to polynomial, and during
+   conversion from polynomial residue to bit pattern.
+   
+   Be rfl8(D) the result of byte-internal mirroring of bit pattern D,
+   and mirr8(d) its corresponding polynom.
+
+   Be now h(a) and l(a) chosen so that: r(mirr8(a)) = h(a) * X * X * X + l(a)
+   This corresponds to highest byte and lower three bytes of crc(A).
+
+      r(mirr8(a) * X + mirr8(b))
+    = r(h(a) * X * X * X * X) + r(l(a) * X) + r(mirr8(b))
+    = l(a)) * X + r(h(a) * X * X * X * X + mirr8(b))
+
+   The corresponding bit pattern operation is
+
+      crc(mirrored byte string A expanded by mirrored byte B)
+    = (lowest_three_bytes(crc(A)) << 8) ^ crc(high_byte(crc(A)) ^ rfl8(B))
+
+   This demands a final result mirroring to meet the ECMA-130 prescription.
+
+   rfl8() can be implemented as lookup table.
+
+   The start value of the bit shifting iteration is 0x00000000, which leads
+   to the same start value for the table driven byte shifting.

+
+   Above function yields sufficient performance, nevertheless the old function
+   crc_32() (see below) is faster by avoiding the additional mirror table
+   lookup.
+   A test with 10 times 650 MB on 3000 MHz amd64:
+     crc_18001801b  :  187 s
+     crc32_by_tab   :   27 s
+     crc_32         :   16 s
+
+   So how does crc_32() avoid the application of bit mirroring to B ?.
+
+   Inherited crc_32() performs
+		crc = crc32_table[(crc ^ *data++) & 0xffL] ^ (crc >> 8);
+
+   Above function crc32_by_tab() would be
+		crc = crc_tab[(crc >> 24) ^ mirr_tab[*data++]] ^ (crc << 8);
+
+   The shortcut does not change the polynomial representation of the algorithm
+   or the mapping from and to bit patterns. It only mirrors the bit direction
+   in the bytes and in the 32-bit words which are involved in the bit pattern
+   computation. This affects input (which is desired), intermediate state
+   (which is as good as unmirrored), and final output (which would be slightly
+   undesirable if libburn could not use the mirrored result anyway).
+   
+   Instead of the high byte (crc >> 24), the abbreviated algorithm uses
+   the low byte of the mirrored intermediate checksum (crc & 0xffL).
+   Instead of shifting the other three intermediate bytes to the left
+   (crc << 8), the abbreviated algorithm shifts them to the right (crc >> 8).
+   In both cases they overwrite the single byte that was used for computing
+   the table index.
+
+   The byte indexed table of CRC values needs to hold mirrored 32 bit values.
+   The byte index [(crc ^ *data++) & 0xffL] would need to be mirrored, which
+   would eat up the gain of not mirroring the input bytes. But this mirroring
+   can be pre-computed into the table by exchanging each value with the value
+   of its mirrored index.
+   
+   So this relation exists between the CRC table crc_tab[] of crc32_by_tab()
+   and the table crc32_table[] of the abbreviated algorithm crc_32():
+
+     crc_tab[i] == rfl32(crc32_table[rfl8(i)])
+
+   for i={0..255}. 
+
+   I compared the generated table in crc32_by_tab() by this test
+                for (i = 0; i < 256; i++) {
+                        if (rfl32(crc_tab[rfl8(i)]) != crc32_table[i] ||

+                        }

+     http://www.cs.utk.edu/~plank/plank/papers/CS-96-332.pdf
+   by James S. Plank after an e-mail exchange with Norbert Preining.
+
+   The output has been compared with the output of the old code of libburn
+   which was labeled "borrowed HEAVILY from cdrdao" and claimed by Joerg
+   Schilling to stem from code by Heiko Eissfeldt.

+   Note: In this text, "^" denotes exponentiation and not the binary exor
+         operation. Confusingly in the C code "^" is said exor.
+   Note: This is not C1, C2 which is rather mentioned in ECMA-130 Annex C and
+         always performed inside the drive.
+   -------------------------------------------------------------------------
+
+
+                            RSPC resp. P- and Q-Parity
+
+   ECMA-130 Annex A prescribes to compute the parity bytes for P-columns and
+   Q-diagonals by RSPC based on a Galois Field GF(2^8) with enumerating
+   polynomials x^8+x^4+x^3+x^2+1 (i.e. 0x11d) and x^1 (i.e. 0x02).
+   Bytes 12 to 2075 of a audio-sized sector get ordered in two byte words
+   as 24 rows and 43 columns. Then this matrix is split into a LSB matrix
+   and a MSB matrix of the same layout. Parity bytes are to be computed
+   from these 8-bit values.
+   2 P-bytes cover each column of 24 bytes. They get appended to the matrix
+   as rows 24 and 25.
+   2 Q-bytes cover each the 26 diagonals of the extended matrix.
+
+   Both parity byte pairs have to be computed so that extended rows or
+   diagonals match this linear equation:
+      H x V = (0,0)
+   H is a 2-row matrix of size n matching the length of the V ectors
+     [   1        1     ...   1   1 ]
+     [ x^(n-1)  x^(n-2)      x^1  1 ]
+   Vp represents a P-row. It is a byte vector consisting of row bytes at
+   position 0 to 23 and the two parity bytes which shall be determined
+   at position 24 and 25. So Hp has 26 columns.
+   Vq represents a Q-diagonal. It is a byte vector consisting of diagonal
+   bytes at position 0 to 42 and the two parity bytes at position 43 and 44.
+   So Hq has 45 columns. The Q-diagonals cover P-parity bytes.
+
+   By applying some high school algebra one gets the parity bytes b0, b1 of
+   vector V = (n_payload_bytes, b0 , b1) as
+
+     b0 = ( H[n] * SUM(n_payload_bytes) - H[0..(n-1)] x n_payload_bytes )
+          / (H[n+1] - H[n])
+     b1 = - SUM(n_payload_bytes) - b0
+
+   H[i] is the i-the element of the second row of matrix H. E.g. H[0] = x^(n-1)
+   The result has to be computed by Galois field arithmetics. See below.
+
+   The P-parity bytes of each column get reunited as LSB and MSB of two words.
+   word1 gets written to positions 1032 to 1074, word0 to 1075 to 1117.
+   The Q-parity bytes of each diagonal get reunited too. word1 goes to 1118
+   to 1143, word0 to 1144 to 1169.
+   >>> I do not read this swap of word1 and word0 from ECMA-130 Annex A.
+   >>> But the new output matches the old output only if it is done that way.
+   >>> See correctness reservation below.
+
+   Algebra on Galois fields is the same as on Rational Numbers.
+   But arithmetics is defined by operations on polynomials rather than the
+   usual integer arithmetics on binary numbers.
+   Addition and subtraction are identical with the binary exor operator.
+   Multiplication and division would demand polynomial division, e.g. by the
+   euclidian algorithm. The computing path over logarithms and powers follows
+   algebra and allows to reduce the arithmetic task to table lookups, additions
+   modulo 255, and exor operations. Note that the logarithms are natural
+   numbers, not polynomials. They get added or subtracted by the usual addition
+   (not by exor) and their polynomial power depends on their value modulo 255.
+
+   Needed are a logarithm table and a power table (or inverse logarithm table)
+   for Galois Field GF(2^8) which will serve to perform the peculiar
+   multiplication and division operation of Galois fields.
+
+   The power table is simply an enumeration of x^n accorting to
+   GF-multiplication. It also serves as second line of matrix H for the parity
+   equations:
+     Hp[i] = gfpow[25-i] , i out of {0,..,25}
+     Hq[i] = gfpow[44-i] , i out of {0,..,44}
+
+   The logarithm table is the inverse permutation of the power table.
+
+   Some simplifications apply to the implementation:
+   In the world of Galois fields there is no difference between - and +.
+   The term (H[n+1] - H[n]) is constant: 3.

+                                 Scrambling
+
+   ECMA-130 Annex B prescribes to exor the byte stream of an audio-sized sector
+   with a sequence of pseudo random bytes. It mentions polynomial x^15+x+1 and
+   a 15-bit register.
+   It shows a diagram of a Feedback Shift Register with 16 bit boxes, though.
+ 
+   Comparing this with explanations in 
+     http://www.newwaveinstruments.com/resources/articles/m_sequence_linear_feedback_shift_register_lfsr.htm
+   one can recognize the diagram as a Fibonacci Implementation. But there seems
+   really to be one bit box too many.
+
+   The difference of both lengths is expressed in function next_bit() by
+   the constants 0x3fff,0x4000 for 15 bit versus 0x7fff,0x8000 for 16 bits.
+   Comparing the output of both alternatives with the old scrambler output
+   lets 15 bit win for now.
+
+   So the prescription is to start with 15 bit value 1, to use the lowest bit
+   as output, to shift the bits down by one, to exor the output bit with the
+   next lowest bit, and to put that exor result into bit 14 of the register.
+
+   -------------------------------------------------------------------------
+
+
+                             Correctness Reservation
+
+   In both cases, parity and scrambling, the goal for now is to replicate the
+   output of the dismissed old lec.c by output which is based on published
+   specs and own implementation code. Whether they comply to ECMA-130 is a
+   different question which can only be answered by real test cases for
+   raw CD recording.
+
+   Of course this implementation will be corrected so that it really complies
+   to ECMA-130 as soon as evidence emerges that it does not yet.

+
+This is the main operating system dependent SCSI part of libburn. It implements
+the transport level aspects of SCSI control and command i/o.
+
+Present implementation: NetBSD 6, ioctl SCIOCCOMMAND
+                        >>> ??? for OpenBSD too ?
+
+PORTING:
+
+Porting libburn typically will consist of adding a new operating system case
+to the following switcher files:
+  os.h    Operating system specific libburn definitions and declarations.
+  sg.c    Operating system dependent transport level modules.
+and of deriving the following system specific files from existing examples:
+  os-*.h  Included by os.h. You will need some general system knowledge
+          about signals and knowledge about the storage object needs of your
+          transport level module sg-*.c.
+
+  sg-*.c  This source module. You will need special system knowledge about
+          how to detect all potentially available drives, how to open them,
+          eventually how to exclusively reserve them, how to perform
+          SCSI transactions, how to inquire the (pseudo-)SCSI driver.
+          You will not need to care about CD burning, MMC or other high-level
+          SCSI aspects.
+
+Said sg-*.c operations are defined by a public function interface, which has
+to be implemented in a way that provides libburn with the desired services:
+
+sg_id_string()          returns an id string of the SCSI transport adapter.
+                        It may be called before initialization but then may
+                        return only a preliminary id.
+
+sg_initialize()         performs global initialization of the SCSI transport
+                        adapter and eventually needed operating system
+                        facilities. Checks for compatibility of supporting
+                        software components.
+
+sg_shutdown()           performs global finalizations and releases golbally
+                        aquired resources.
+
+sg_give_next_adr()      iterates over the set of potentially useful drive 
+                        address strings.
+
+scsi_enumerate_drives() brings all available, not-whitelist-banned, and
+                        accessible drives into libburn's list of drives.
+
+sg_dispose_drive()      finalizes adapter specifics of struct burn_drive
+                        on destruction. Releases resources which were aquired
+                        underneath scsi_enumerate_drives().
+ 
+sg_drive_is_open()      tells wether libburn has the given drive in use.
+
+sg_grab()               opens the drive for SCSI commands and ensures
+                        undisturbed access.
+
+sg_release()            closes a drive opened by sg_grab()
+
+sg_issue_command()      sends a SCSI command to the drive, receives reply,
+                        and evaluates wether the command succeeded or shall
+                        be retried or finally failed.
+
+sg_obtain_scsi_adr()    tries to obtain SCSI address parameters.
+
+
+burn_os_is_2k_seekrw()  tells whether the given path leads to a file object
+                        that can be used in 2 kB granularity by lseek(2),
+                        read(2), and possibly write(2) if not read-only..
+                        E.g. a USB stick or a hard disk.
+
+burn_os_stdio_capacity()  estimates the emulated media space of stdio-drives.
+
+burn_os_open_track_src()  opens a disk file in a way that allows best
+                        throughput with file reading and/or SCSI write command
+                        transmission.
+
+burn_os_alloc_buffer()  allocates a memory area that is suitable for file
+                        descriptors issued by burn_os_open_track_src().
+                        The buffer size may be rounded up for alignment
+                        reasons.
+
+burn_os_free_buffer()   delete a buffer obtained by burn_os_alloc_buffer().
+

+
+This is the main operating system dependent SCSI part of libburn. It implements
+the transport level aspects of SCSI control and command i/o.
+
+Present implementation: Solaris uscsi, e.g. for SunOS 5.11
+
+
+PORTING:
+
+Porting libburn typically will consist of adding a new operating system case
+to the following switcher files:
+  os.h    Operating system specific libburn definitions and declarations.
+  sg.c    Operating system dependent transport level modules.
+and of deriving the following system specific files from existing examples:
+  os-*.h  Included by os.h. You will need some general system knowledge
+          about signals and knowledge about the storage object needs of your
+          transport level module sg-*.c.
+
+  sg-*.c  This source module. You will need special system knowledge about
+          how to detect all potentially available drives, how to open them,
+          eventually how to exclusively reserve them, how to perform
+          SCSI transactions, how to inquire the (pseudo-)SCSI driver.
+          You will not need to care about CD burning, MMC or other high-level
+          SCSI aspects.
+
+Said sg-*.c operations are defined by a public function interface, which has
+to be implemented in a way that provides libburn with the desired services:
+
+sg_id_string()          returns an id string of the SCSI transport adapter.
+                        It may be called before initialization but then may
+                        return only a preliminary id.
+
+sg_initialize()         performs global initialization of the SCSI transport
+                        adapter and eventually needed operating system
+                        facilities. Checks for compatibility of supporting
+                        software components.
+
+sg_shutdown()           performs global finalizations and releases golbally
+                        aquired resources.
+
+sg_give_next_adr()      iterates over the set of potentially useful drive 
+                        address strings.
+
+scsi_enumerate_drives() brings all available, not-whitelist-banned, and
+                        accessible drives into libburn's list of drives.
+
+sg_dispose_drive()      finalizes adapter specifics of struct burn_drive
+                        on destruction. Releases resources which were aquired
+                        underneath scsi_enumerate_drives().
+ 
+sg_drive_is_open()      tells wether libburn has the given drive in use.
+
+sg_grab()               opens the drive for SCSI commands and ensures
+                        undisturbed access.
+
+sg_release()            closes a drive opened by sg_grab()
+
+sg_issue_command()      sends a SCSI command to the drive, receives reply,
+                        and evaluates wether the command succeeded or shall
+                        be retried or finally failed.
+
+sg_obtain_scsi_adr()    tries to obtain SCSI address parameters.
+
+
+burn_os_is_2k_seekrw()  tells whether the given path leads to a file object
+                        that can be used in 2 kB granularity by lseek(2),
+                        read(2), and possibly write(2) if not read-only..
+                        E.g. a USB stick or a hard disk.
+
+burn_os_stdio_capacity()  estimates the emulated media space of stdio-drives.
+
+burn_os_open_track_src()  opens a disk file in a way that allows best
+                        throughput with file reading and/or SCSI write command
+                        transmission.
+
+burn_os_alloc_buffer()  allocates a memory area that is suitable for file
+                        descriptors issued by burn_os_open_track_src().
+                        The buffer size may be rounded up for alignment
+                        reasons.
+
+burn_os_free_buffer()   delete a buffer obtained by burn_os_alloc_buffer().
+
+Porting hints are marked by the text "PORTING:".

   Before you can do anything, you have to initialize libburn by

   and provide some signal and abort handling, e.g. by the builtin handler, by
-     burn_set_signal_handling() 
-  as it is done in main() at the end of this file. Then you aquire a

+  Then you aquire a drive in an appropriate way conforming to the API. The twoi
+  main approaches are shown here in application functions:
      libburner_aquire_by_adr()     demonstrates usage as of cdrecord traditions

-  With that aquired drive you can blank a CD-RW

+  With that aquired drive you can blank a CD-RW or DVD-RW as shown in
      libburner_blank_disc()
   or you can format a DVD-RW to profile "Restricted Overwrite" (needed once)

      libburner_format()
-  With the aquired drive you can burn to CD, DVD, BD
+  With the aquired drive you can burn to CD, DVD, BD. See

+  These three functions switch temporarily to a non-fatal signal handler
+  while they are waiting for the drive to become idle again:
+     burn_set_signal_handling("libburner : ", NULL, 0x30)
+  After the waiting loop ended, they check for eventual abort events by
+     burn_is_aborting(0)
+  The 0x30 handler will eventually execute
+     burn_abort()
+  but not wait for the drive to become idle and not call exit().
+  This is needed because the worker threads might block as long as the signal
+  handler has not returned. The 0x0 handler would wait for them to finish.
+  Take this into respect when implementing own signal handlers.

-
-We, the copyright holders, agree on the interpretation that

-If there should really arise the case where above clarification
-does not suffice to fulfill a clear and neat request in open source
-spirit that would otherwise be declined for mere formal reasons,

-It is the open source idea of responsible freedom which will be
