 libisofs is part of the libburnia project (libburnia-project.org)
-------------------------------------------------------------------------------
-
-libisofs is a library to create an ISO-9660 filesystem, and supports extensions
-like RockRidge or Joliet. It is also a full featured ISO-9660 editor, allowing 
-you to modify an ISO image or multisession disc, including file addition and 
-removal, change of file names and attributes, etc
-
-Features:
----------
-
-- Image creation
-	- Creates ISO-9660 images from local files.
-	- Support for RockRidge and Joliet extensions.
-	- Support for ISO-9660:1999 (version 2)
-	- Support for El-Torito bootable images.
-	- Full featured edition of file names and attributes on the image.
-	- Several options to relax ISO-9660 constraints.
-	- Special options for images intended for distribution (suitable default
-	  modes for files, hiding of real timestamps...)
-- Multisession
-	- Support for growing an existing image
-	- Full-featured edition of the image files, including: addition of new
-	  files, removing of existent files, moving files, renaming files,
-	  change file attributes (permissions, timestamps...)
-	- Support for "emulated multisession" or image growing, suitable for non
-	  multisession media such as DVD+RW
-- Image modification
-	- It can create a completely new image from files on another image.
-	- Full-featured edition of image contents
-- Others
-	- Handling of different input and output charset
-	- Good integration with libburn for image burning.
-	- Reliable, good handling of different kind of errors.
-
-Requirements:
--------------
-
-- libburn 0.4.2 headers must be installed at compile time. It is not required
-  at runtime.
-  
-Know bugs:
-----------
-
-Multisession and image growing can lead to undesired results in several cases:
-
-a) Images with unsupported features, such as:
-	- UDF.
-	- HSF/HFS+ or other Mac extensions.
-	- El-Torito with multiple entries.
-	- ECMA-119 with extended attributes, multiple extends per file.
-	- Non El-Torito boot info.
-	- zisofs compressed images.
-	- ...
-   In all these cases, the resulting new image (or new session) could lack some
-   features of the original image.
-   In some cases libisofs will issue warning messages, or even refuse to grow
-   or modify the image. Others remain undetected. Images created with libisofs
-   do not have this problems.
-
-b) Bootable El-Torito images may have several problems, that result in a new
-   image that is not bootable, or that boots from an outdated session. In many
-   cases it is recommended to add boot info again in the new session.
-   
-    - isolinux images won't be bootable after a modify. This is because 
-      isolinux images need to have hardcoded the root dir lba. libisofs cannot 
-      know whether an image is an isolinux image or not, so the user is 
-      responsible to tell libisofs that it must patch the image, with the
-      el_torito_patch_isolinux_image() function. This problem could also exists
-      on other boot images.
-	- Most boot images are highly dependent of the image contents, so if the 
-	  user moves or removes some files on image it is possible they won't boot 
-	  anymore.
-	- There is no safer way to modify hidden boot images, as the size of the 
-	  boot image can't be figured out.
-
-c) Generated images could have different ECMA-119 low level names, due to 
-   different way to mangle names, to new files added that force old files to 
-   be renamed, to different relaxed contraints... This only affect the 
-   ISO-9660 info, not the RR names, so it shouldn't be a problem in most
-   cases. If your app. relies on low level ISO-9660 names, you will need to 
-   ensure all node names are valid ISO names (maybe together with some
-   relaxed contraints), otherwise libisofs might arbitrarily change the names.

-                        Overview of libburnia-project.org
+libisofs is a library to create an ISO-9660 filesystem, supports extensions
+like RockRidge or Joliet, and introduces an own extension AAIP.
+It is a full featured ISO-9660 editor which composes and changes the directory
+tree of an ISO image. This tree and its newly imported data file contents get
+then written as independent single-session image or as add-on session for the
+image from where the tree was originally loaded.
 
-libburnia-project.org is an open-source software project for reading, mastering
+Features:
-and writing optical discs.
+---------
-For now this means only CD media and all single layer DVD media except DVD+R.
 
-The project comprises of several more or less interdependent parts which

-together strive to be a usable foundation for application development.
+	- Creates ISO-9660 images from local files.
-These are libraries, language bindings, and middleware binaries which emulate
+	- Support for RockRidge and Joliet extensions.
-classical (and valuable) Linux tools.
+	- Support for ISO-9660:1999 (version 2).
+	- Support for El-Torito bootable images. Tested are: PC-BIOS and EFI.
+	- Support for multi-extent data files up to 400 GB (level 3).
+	- Full-featured edition of the image files, including: addition of new
+	  files, removing of existent files, moving files, renaming files,
+	  change file attributes (permissions, timestamps...)
+	- Optional recording per file of non-ISO 9660 features:
+	  ACL, xattr, content MD5, hard link relations.
+	  They do not hamper image readability by operating systems but can be
+	  retrieved only via libisofs.
+	- Optional zisofs compression, gzip compression, external filter
+	  processes.
+	- Several options to relax ISO-9660 constraints.
+	- Special options for images intended for distribution (suitable
+	  default modes for files, hiding of real timestamps...).
+- Image reading
+	- Image tree and data heap can be verified by stream reading and
+	  eventually recorded MD5 tags.
+	- Directory tree and file attributes of ISO 9660 session get loaded
+	  into memory for editing or for extraction into local filesystem.
+	- File content can be read by applications.
+	- Automatic zisofs decompression.
+	- Optional application of gzip decompression or external filter
+	  processes.
+	- Eventually recorded MD5 of data file can be obtained, MD5 of data
+	  stream can be computed and compared.
+	- Helper functions for restoring ACL and/or xattr to the local
+	  filesystem.
+- Multisession
+	- Support for growing an existing image on multi-session media.
+	- Support for "emulated multisession" on overwriteable media such as
+	  DVD+RW, USB sticks, regular files.
+	- Support for blindly prepared add-on sessions (mkisofs style -M -C)
+	  suitable for pipes which lead to an external burn program.
+- Image modification
+	- Creates a completely new image from files out of another image and
+	  eventual editing operations. Suitable for any target medium.

+Know bugs:
+----------
 
-- libburn  is the library by which preformatted data get onto optical media.
+Multisession and image growing can lead to undesired results in several cases:
-           It uses either /dev/sgN (e.g. on kernel 2.4 with ide-scsi) or
-           /dev/hdX (e.g. on kernel 2.6).
-           libburn is the foundation of our cdrecord emulation. Its code is
-           independent of cdrecord. Its DVD capabilities are learned from
-           studying the code of dvd+rw-tools and MMC-5 specs. No code but only
-           the pure SCSI knowledge has been taken from dvd+rw-tools, though.
 
-- libisofs is the library to pack up hard disk files and directories into a
+a) Images with unsupported features, such as:
-           ISO 9660 disk image. This may then be brought to media via libburn.
+	- UDF.
-           libisofs is to be the foundation of our upcoming mkisofs emulation.
+	- HSF/HFS+ or other Mac extensions.
+	- ECMA-119 Extended attributes.
+	- Non El-Torito boot info.
+	- ...
+   In all these cases, the resulting new image (or new session) could lack some
+   features of the original image. Nevertheless, the ECMA-119 System Area with
+   an eventual Master Boot Record gets preserved by default.
+   In some cases libisofs will issue warning messages, or even refuse to grow
+   or modify the image. Others remain undetected. Images created with libisofs
+   do not have this problems.
 
-- cdrskin  is a limited cdrecord compatibility wrapper for libburn.
+b) Bootable El-Torito images may have several problems, that result in a new
-           Cdrecord is a powerful GPL'ed burn program included in Joerg
+   image that is not bootable, or that boots from an outdated session. In many
-           Schilling's cdrtools. cdrskin strives to be a second source for
+   cases it is recommended to add boot info again in the new session.
-           the services traditionally provided by cdrecord. Additionally it
-           provides libburn's DVD capabilities, where only -sao is compatible
-           with cdrecord.
-           cdrskin does not contain any bytes copied from cdrecord's sources.
-           Many bytes have been copied from the message output of cdrecord
-           runs, though.
-           See cdrskin/README and man cdrskin/cdrskin.1 for more.
    
-- test     is a collection of application gestures and examples given by the
+    - isolinux images won't be bootable after a modify. This is because 
-           authors of the library features. The main API example for libburn
+      isolinux images need to have hardcoded the root dir lba in their boot
-           is test/libburner.c .
+      information table.
-           Explore these examples if you look for inspiration.
+      libisofs makes an educated guess at load time whether a boot image
+      contains such a table. Its outcome can be inquired by call
+      el_torito_seems_boot_info_table().
+      If one knows to have isolinux or GRUB El-Torito-bootable images, or if
+      a boot information table seems to exist, it is advised to apply the
+      el_torito_patch_isolinux_image() function.
+      Most boot images are highly dependent of the image contents, so if the 
+      user moves or removes some files on image it is possible they won't boot 
+      anymore.
+    - There is no safe way to modify hidden boot images, as the size of the 
+      boot image can't be figured out.

-  The site of this founder team is reachable and offers download of a
-  (somewhat outdated) tarball and from CVS :
-     http://icculus.org/burn/
-  Copyright holders and most probably founders:
-  Derek Foreman and Ben Jansens.
-
-- I came to using libburn in 2005. Founded the cdrskin project and submitted
-  necessary patches which were accepted or implemented better. Except one
-  remaining patch which prevented cdrskin from using vanilla libburn from CVS.
-  The cdrskin project site is reachable and offers download of the heavily
-  patched (elsewise outdated) tarball under the name  cdrskin-0.1.2  :
-     http://scdbackup.sourceforge.net/cdrskin_eng.html
-  It has meanwhile moved to use vanilla libburn.pykix.org , though.
-  Version 0.1.4 constitutes the first release of this kind.
-
-- In July 2006 our team mate Mario Danic announced a revival of libburn
-  which by about nearly everybody else was perceived as unfriendly fork.
-  Derek Foreman four days later posted a message which expressed his
-  discontent.
-  The situation first caused me to publically regret it and then - after i
-  got the opportunity to move in with cdrskin - gave me true reason to
-  personally apologize to Derek Foreman, Ben Jansens and the contibutors at 
-  icculus.org/burn. Posted to both projects:
-    http://lists.freedesktop.org/archives/libburn/2006-August/000446.html
-    http://mailman-mail1.webfaction.com/pipermail/libburn-hackers/2006-August/000024.html
-
-- Mid August 2006 project cdrskin established a branch office in 
-  libburn.pykix.org so that all maintainers of our tools have one single place
-  to get the current (at least slightely) usable coordinated versions of
-  everything.
-  Project cdrskin will live forth independendly for a while but it is committed
-  to stay in sync with libburn.pykix.org (or some successor, if ever).
-  cdrskin is also committed to support  icculus.org/burn  if the pending fork
-  is made reality by content changes in that project. It will cease to maintain
-  a patched version of  icculus.org/burn  though. Precondition for a new
-  release of cdrskin on base of  icculus.org/burn  would be the pending
-  "whitelist patch" therefore.
-  I would rather prefer if both projects find consense and merge, or at least
-  cooperate. I have not given up hope totally, yet.
-  I, personally, will honor any approach.
-
-- 2nd September 2006 the decision is made to strive for a consolidation of
-  copyright and a commitment to GPL in a reasonable and open minded way.
-  This is to avoid long term problems with code of unknown origin and
-  with finding consense among the not so clearly defined group of copyright
-  claimers and -holders.
-  libisofs is already claimed sole copyright Mario Danic.
-  cdrskin and libburner are already claimed sole copyright Thomas Schmitt.
-  Rewrites of other components will follow and concluded by claiming full
-  copyright within the group of libburn.pykix.org-copyright holders.
-
-- 16th September 2006 feature freeze for release of libburn-0.2.2 .
-
-- 20th September 2006 release of libburn-0.2.2 .
-
-- 26th October 2006 feature freeze for cdrskin-0.2.4 based on libburn-0.2.3 .
-  This version of cdrskin is much more cdrecord compatible in repect
-  to drive addressing and audio features.
-
-- 30th October 2006 release of cdrskin-0.2.4 .
-
-- 13th November 2006 splitting releases of libburn+cdrskin from libisofs.
-
-- 24th November 2006 release of libburn-0.2.6 and cdrskin-0.2.6 . cdrskin has
-  become suitable for unaware frontends as long as they perform only the core 
-  of cdrecord use cases (including open-ended input streams, audio, and
-  multi-session).
-
-- 28th November 2006 the umbrella project which encloses both, libisofs and
-  libburn, is now called libburnia. For the origin of this name, see 
-  http://en.wikipedia.org/wiki/Liburnians .
-
-- 16th January 2007 release of libburn-0.3.0 and cdrskin-0.3.0 . Now the scope
-  is widened to a first class of DVD media: overwriteable single layer types
-  DVD-RAM, DVD+RW, DVD-RW. This is not a cdrecord emulation but rather inspired
-  by dvd+rw-tools' "poor man" writing facility for this class of media.
-  Taking a bow towards Andy Polyakov.
-
-- 11th February 2007 version 0.3.2 covers sequential DVD-RW and DVD-R with
-  multi-session and with DAO.
-
-- 12th March 2007 version 0.3.4 supports DVD+R and thus covers all single layer
-  DVD media. Code for double layer DVD+/-R is implemented but awaits a tester
-  yet.
-
-- 23th April 2007 version 0.3.6 follows the unanimous opinion of Linux kernel
-  people that one should not use /dev/sg on kernel 2.6.
-
-- 31st July 2007 version 0.3.8 marks the first anniversary of libburn revival.
-  We look back on improved stability, a substantially extended list of media
-  and write modes, and better protection against typical user mishaps.
-
-- 24th October 2007 version 0.4.0 is the foundation of new library libisoburn
-  and an upcomming integrated application for manipulating and writing
-  ISO 9660 + Rock Ridge images. cdrskin-0.4.0 got capabilities like growisofs
-  by these enhancements: growing of overwriteable media and disk files.
-  Taking again a bow towards Andy Polyakov.
-
-- 26th Januar 2008 version 0.4.2 rectifies the version numbering so that we
-  reliably release libburn.so.4 as should have been done since libburn-0.3.2.
-  cdrskin now is by default linked dynamically and does a runtime check
-  to ensure not to be started with a libburn which is older than itself.

+
+The blobs are available in the Syslinux build tree under the names:
+
+mbr/isohdp[fp]x*.bin
+
+The default probably should be mbr/isohdppx.bin, but it's ultimately up
+to the user.
+
+User definable parameters:
+
+-> MBR ID		(default random 32-bit number,
+			 or preserved from previous instance)
+-> Sector count		(default 32, range 1-63)
+-> Head count		(default 64, range 1-256)
+-> Partition offset	(default 0, range 0-64)
+-> Partition number	(default 1, range 1-4)
+-> Filesystem type	(default 0x17, range 1-255)
+
+Note: the filesystem type is largely arbitrary, in theory it can be any
+value other than 0x00, 0x05, 0x0f, 0x85, 0xee, or 0xef.  0x17 ("Windows
+IFS Hidden") seems safeish, some people believe 0x83 (Linux) is better.
+
+Here is the prescriptions for how to install it:
+
+All numbers are littleendian.  "word" means 16 bits, "dword" means 32
+bits, "qword" means 64 bits.
+
+Common subroutine LBA_to_CHS():
+	s = (lba % sector_count) + 1

+	c = (t / head_count)
+
+	if (c >= 1024):
+		c = 1023
+		h = head_count
+		s = sector_count
+
+	s = s | ((c & 0x300) >> 2)
