   Lua alternative to the makeglossaries Perl script.

Since Lua has limitations, this script isn't an exact
   replacement to the Perl script. In particular the makeglossaries -d 
   switch isn't implemented in this Lua version.
   This also doesn't provide the more detailed diagnostics that the Perl
   version does nor does it attempt any language mappings. Since xindy
   requires Perl, don't use this script if you want to use xindy. Instead
   use the Perl makeglossaries script.

     - Added extra info to error message on -d
     - Fixed bug #183 that occurs when \@istfilename is missing
     - Only add double-quotes if text contains any spaces which

Syntax : makeglossaries-lite [options] <filename>

For use with the glossaries package to pass relevant
files to makeindex or xindy.

<filename>	Base name of glossary file(s). This should
		be the name of your main LaTeX document without any
		extension. If you do add an extension, only that
		glossary file will be processed.

General Options:

-o <gls>	Use <gls> as the output file.
		(Don't use -o if you have more than one glossary.)
-s <sty>	Employ <sty> as the style file.
-t <log>	Employ <log> as the transcript file.
		(Don't use -t if you have more than one glossary
		or the transcripts will be overwritten.)
-q		Quiet mode.
-l		Letter ordering.
-n		Print the command that would normally be executed,
		but don't execute it (dry run).
--help		Print this help message.
--version	Print the version.

Xindy Options:

-L <language>	Use <language>.
-x <file>	Full path to xindy executable.
		(Default assumes xindy is on the operating system's path.)

Makeindex Options:
(See makeindex documentation for further details on these options.)

-c		Compress intermediate blanks.
-g		Employ German word ordering.
-p <num>	Set the starting page number to be <num>.
-r		Disable implicit page range formation.
-m <file>	Full path to makeindex executable.
		(Default assumes makeindex is on the operating system's path.)

This is a light-weight Lua alternative to the makeglossaries Perl script.
If you want to use xindy, it's better to use the Perl makeglossaries version
instead.
