/*
cdrskin.c , Copyright 2006-2007 Thomas Schmitt <scdbackup@gmx.net>
Provided under GPL version 2. See future commitment below.
A cdrecord compatible command line interface for libburn.
This project is neither directed against original cdrecord nor does it exploit
any source code of said program. It rather tries to be an alternative method
to burn CD or DVD, which is not based on the same code as cdrecord.
See also : http://scdbackup.sourceforge.net/cdrskin_eng.html
Interested users of cdrecord are encouraged to contribute further option
implementations as they need them. Contributions will get published under GPL
but it is essential that the authors allow a future release under LGPL and/or
BSD license.
There is a script test/cdrecord_spy.sh which may be installed between
the cdrecord command and real cdrecord in order to learn about the options
used by your favorite cdrecord frontend. Edit said script and install it
according to the instructions given inside.
The implementation of an option would probably consist of
- necessary structure members for structs CdrpreskiN and/or CdrskiN
- code in Cdrpreskin_setup() and Cdrskin_setup() which converts
argv[i] into CdrpreskiN/CdrskiN members (or into direct actions)
- removal of option from ignore list "ignored_partial_options" resp.
"ignored_full_options" in Cdrskin_setup()
- functions which implement the option's run time functionality
- eventually calls of those functions in Cdrskin_run()
- changes to be made within Cdrskin_burn() or Cdrskin_blank() or other
existing methods
See option blank= for an example.
------------------------------------------------------------------------------
For a more comprehensive example of the advised way to write an application
of libburn see test/libburner.c .
------------------------------------------------------------------------------
This program is currently copyright Thomas Schmitt only.
The copyrights of several components of libburnia-project.org are willfully
tangled at toplevel to form an irrevocable commitment to true open source
spirit.
We have chosen the GPL for legal compatibility and clearly express that it
shall not hamper the use of our software by non-GPL applications which show
otherwise the due respect to the open source community.
See toplevel README and cdrskin/README for that commitment.
For a short time, this place showed a promise to release a BSD license on
mere request. I have to retract that promise now, and replace it by the
promise to make above commitment reality in a way that any BSD conformant
usage in due open source spirit will be made possible somehow and in the
particular special case. I will not raise public protest if you fork yourself
a BSD license from an (outdated) cdrskin.c which still bears that old promise.
Note that this extended commitment is valid only for cdrskin.[ch],
cdrfifo.[ch] and cleanup.[ch], but not for libburnia-project.org as a whole.
cdrskin is originally inspired by libburn-0.2/test/burniso.c :
(c) Derek Foreman <derek@signalmarketing.com> and Ben Jansens <xor@orodu.net>
