+  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().

-Clarification in my name and in the name of Mario Danic, copyright holder
-on toplevel of libburnia. To be fully in effect after the remaining other
-copyrighted code has been replaced by ours and by copyright-free contributions
-of our friends:
-
-We, the copyright holders, agree on the interpretation that
-dynamical linking of our libraries constitutes "use of" and
-not "derivation from" our work in the sense of GPL, provided
-those libraries are compiled from our unaltered code.
-
-Thus you may link our libraries dynamically with applications
-which are not under GPL. You may distribute our libraries and
-application tools in binary form, if you fulfill the usual
-condition of GPL to offer a copy of the source code -altered
-or unaltered- under GPL.
-
-We ask you politely to use our work in open source spirit
-and with the due reference to the entire open source community.
-
-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,
-only in that case we will duely consider to issue a special license
-covering only that special case.
-It is the open source idea of responsible freedom which will be
-decisive and you will have to prove that you exhausted all own
-means to qualify for GPL.
-
-For now we are firmly committed to maintain one single license: GPL.
