// Changelog:
// 11-09-2008 - Added sanity checks for the lenght of log file path and
//              destination folder (both should not exceed 120 characters)
//            - Added -progtc, -progfr, -chaptc, -chapfr switches
//              to support the generation of programs and chapters
//              in the DVD compilation
//            - Bugfix. Corrected a mistake, introduced in version 1.2,
//              concerning the wrong attribution of chapters in multi-title
//              compilations
// 25-08-2008 - First release supporting multipage menues, hardcoded
//              organisation and navigation
//            - Completely reworked the harcoded navigation for static and
//              motion menus
//            - Removed all -hcni switches; now the navigation is partially
//              configurable by means of a proper cfg file
//            - Added -hcn file_name switch, to support the configuration
//              of the hardcoded navigation
//            - Changed the default assignement, in the mxp output, of the
//              -[SEGi]hlbset[_j] argument. Now it is set to -1, instead
//              of 00:00:00:00; same as for the -[SEGi]hldurat[_j] argument
//            - Radically improved the DVD navigation: now supporting
//              prev&next title jump, the resume function and the titles
//              are now all one-sequential
// 21-07-2008 - Added -prio argument, to set the exec priority of MuxMan.exe
//            - Added -hcn3 and -hcn4 arguments
// 16-05-2007 - First release supporting menues, hardcoded organisation
//              and navigation
//            - Added -hcn1 and -hcn2 arguments
// 24-04-2007 - Introduced the "Content Section" and the "Organisation and
//              Navigation Section" concepts, as first steps to support menus
//            - Added highlight items in the structure of Segments to support
//              highlight streams
//            - Added -[SEGi]hlstart[_j] hh:mm:ss:ff argument
//            - Added -[SEGi]hldurat[_j] hh:mm:ss:ff argument
//            - Added -[SEGi]hlmnu[_j] filename argument
//            - Added -[SEGi]hlbset[_j] hh:mm:ss:ff argument
//            - Added -[SEGi]hlbutm{l}[_j] argument
//            - Added -[SEGi]hloffsbutnr[_j] argument
//            - Added -[SEGi]hlnumselbut[_j] argument
//            - Added -[SEGi]hlfselbutnr[_j] argument
//            - Added -[SEGi]hlfactbutnr[_j] argument
//            - Added -[SEGi]hlcsm[_j] filename argument
//            - Added -[SEGi]but{k}g{l}[_j] filename argument
//            - Bugfix. File list composer was broken. The bug was introduced
//              in the reworking and cleaning up of release 0.8
// 18-01-2007 - Huge cleanup and significant improvements aimed at preparing
//              for the implementation of menus within BatchMux
//            - Bugfix. Not all 32 subtitle streams were properly implemented
//              in release 0.7. Arguments accepted but the mxp content was
//              limited to 8
//            - Bugfix. -norun option was not properly implemented
//            - Bugfix. -ailang option was not properly implemented
//            - Bugfix. -aidelay option was not properly implemented
//            - Reworked, once more, the segment structures (now everything
//              is dynamic)
//            - Changed, with significant simplifications, the whole error
//              handling concept and procedures
//            - Extended to 999 the max number of segments supported by the
//              application
//            - Added support to BMP as valid assets for the video segments
//            - Added -[SEGi]vduration[_j] argument
// 15-12-2006 - Improved. Supporting now up to 8 audio streams and 32 subtitle
//              streams.
//            - Removed "BatchMux:" from the printout text of many params
//            - Added support of file lists to compose the video and audio
//              assets for each segment; this should be helpful for avoiding
//              copy operations and speed up things in multicore environments
//            - Added the -arglist argument, in order to enable an easier
//              handling of the argument list (especially useful for long, or
//              very long argument lists)
// 03-10-2006 - Bugfix. In case no celltimes is specified, an invalid time
//              reference is generated in the mxp file
//            - Bugfix. Missing "break" statement after parsing of "vidmode"
//              argument
//            - Improved. In case DvdPreparer not set, then no need to change
//              VIDEO_TS.IFO and VIDEO_TS.BUP
// 24-09-2006 - Completely reworked the memory usage. Now many structures are
//              allocated dinamically
//            - Reworked and reordered arguments in order to support multi VTS
//              authoring (with navigation hardcoded...). If not present, the
//              optional "SEGi" prefix of the segment arguments, with i in the
//              range 2 ... 99, represents a compatibility mode with previous
//              releases of BatchMux.exe. This simplifies the syntax in case
//              just a single VTS is needed. If present, the tag enables the
//              authoring of additional segments, other than the first, in a
//              simple authoring structure (each additional segment lead to an
//              additional separate VTS, with a single title, and a single pgc
//              per segment)
// 11-09-2006 - Added the -preparer argument; Note: it is overridden by -norun
//            - Improved formatting of log information
// 19-08-2006 - Changed stdout to stderr for the error messages...
//            - Changed the default assignement of subpicture streams display
//              mode; now it is depending on the actual Video Stream AR (both
//              MPEG-2 and MPEG-1): in case the AR is 4:3 it is not harmful to
//              leave the default display mode as unspecified; on the other
//              hand, if the Video Stream AR is 16:9, the DEFAULT subpicture
//              stream display mode is set as WIDE_LB. This should prevent
//              possible unwanted skipping of subpicture streams in the
//              authoring due to not setting of their display mode...
//            - Added the -palette argument, pointing to an ascii file
//              containing the palette colour entries to redefine the default
//              palette of MuxMan.
// 26-07-2006 - Version 0.2
//            - Added the revision history - also in the help printout.
//            - Added the -muxman argument, in order to specify
//              the location of the MuxMan.exe executable.
// 18-07-2006 - First Release
//

Rationale for this tool:
1. Simplicity and straight usage. Even though MuxMan fully supports command
   line arguments, the usage of the whole set of parameters available in the
   GUI is only possible through scripting. The compilation of a MuxMan script
   is very easy indeed - it is sufficient to load files and parametes in the
   GUI and save the project. Anyway the straight command line control provided
   by BatchMux is direct, simple, and it should like to users not familiar or
   not interested in mxp scripting.
2. Enabling of automation for existing applications. The usage of MuxMan as
   a reference authoring application should be encouraged as much as possible.
   The quality of its output is significantly better respect to other authoring
   packages, getting rid - definitely - of "stuttering", "freezing" and other
   sad effects, mostly caused by the bad quality of the mux and authoring.
   The direct integration of MuxMan, as authoring engine into thirdy party
   applications, may turn out as being not possible (or too complex, due to
   the need of creating the mxp MuxMan script).
   BatchMux may be helpful in this sort of scenarios...

Usage: launc BatchMux with the above arguments... No argument, or -help for
   printing out the full listing of CLI arguments...
