/* Command line oriented batch and dialog tool which creates, loads,
manipulates and burns ISO 9660 filesystem images.
Copyright 2007-2009 Thomas Schmitt, <scdbackup@gmx.net>
Initial code of this program was derived from program src/askme.c out
of scdbackup-0.8.8, Copyright 2007 Thomas Schmitt, BSD-License.
Provided under GPL version 2, with the announcement that this might
get changed in future. I would prefer BSD or a modified LGPL with no
option to choose any kind of future GPL version.
(This announcement affects only future releases of xorriso.
If you obtain a copy licensed as "GPL version 2" then this license is
not revocable for that particular copy, of course.)
Overview of xorriso architecture:
libburn provides the ability to read and write data.
libisofs interprets and manipulates ISO 9660 directory trees. It generates
the output stream which is handed over to libburn.
libisoburn encapsulates the connectivity issues between libburn and
libisofs. It also enables multi-session emulation on overwritable media
and random access file objects.
xorriso is intended as reference application of libisoburn.
xorrisoburn.[ch] encapsulate any usage of the libraries by xorriso.
xorriso.h exposes the public functions of xorriso which are intended
to be used by programs which link with xorriso.o. These functions are
direct equivalents of the xorriso interpreter commands.
There is also the API for handling event messages.
xorriso_private.h is not to be included by other software. It encapsulates
the inner interfaces of xorriso.
xorriso.c provides the command interpreter as described in xorriso.1.
It performs any activity that does not demand a reference to a symbol
of the library APIs. This includes:
- Interpretation of user input from arguments, dialog, and scripting.
- Output of result text and event messages.
- POSIX filesystem operations.
- Public functions which perform the particular xorriso commands.
- The main() function, if enabled by #define Xorriso_with_maiN.
