This file contains the implementations of classes:
- FindjoB, ExprnodE, ExprtesT which perform tree searches in

- DirseQ which crawls along a directory's content list.
- ExclusionS which manages the list of excluded file paths and
leaf patterns.
- Xorriso_lsT which provides a generic double-linked list.
- LinkiteM, PermiteM which temporarily record relations and states.

/* Command line oriented batch and dialog tool which creates, loads,
manipulates and burns ISO 9660 filesystem images.
Copyright 2007-2010 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 or later, with the announcement that this
might get changed in future. I would prefer BSD or LGPL as soon as the
license situation of the library code allows that.
(This announcement affects only future releases of xorriso and it will
always be possible to derive a GPLv2+ from the future license.)
There is a derived package "GNU xorriso" under GPLv3+ which combines the
libburnia libraries and program xorriso to a statically linked binary.
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.
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.
The source is divided in two groups:
A set of source modules interacts with the libraries:
base_obj.[ch] fundamental operations of the XorrisO object
lib_mgt.[ch] manages the relation between xorriso and the libraries
drive_mgt.[ch] operates on drives and media
iso_img.[ch] operates on ISO images and their global properties
iso_tree.[ch] access nodes of the libisofs tree model
iso_manip.[ch] manipulates the libisofs tree model
sort_cmp.[ch] sorts and compare tree nodes
write_run.[ch] functions to write sessions
read_run.[ch] functions to read data from ISO image
filters.[ch] operates on data filter objects
xorrisoburn.h declarations needed by the non-library modules
Another set is independent of the liburnia libraries:
parse_exec.c deals with parsing and interpretation of command input
sfile.c functions around files and strings
aux_objects.c various helper classes
misc_funct.c miscellaneous helper functions
findjob.c performs tree searches in libisofs or in POSIX filesystem
check_media.c perform verifying runs on media resp. images
text_io.c text i/o functions
match.c functions for pattern matching
emulators.c emulators for mkisofs and cdrecord
disk_ops.c actions on onjects of disk filesystems
cmp_update.c compare or update files between disk filesystem and
ISO filesystem
opts_a_c.c options -a* to -c*
opts_d_h.c options -d* to -h*
opts_i_o.c options -i* to -o*
opts_p_z.c options -p* to -z*
xorriso_main.c the main program
xorriso_private.h contains the definition of struct Xorriso and for
convenience includes the .h files of the non-library group.
