*
* The latest version of this program can be obtained from
* http://songs.sourceforge.net.
*
*
* This program generates an index.sbx file from an index.sxd file. Index.sxd
* files are generated by the song book LaTeX files while you compile a song
* book. They contain lists of all the song titles, song numbers, and
* scripture references. Once the .sxd files exist, run this program to
* convert them in to .sbx files. This program will sort the song titles
* alphabetically, group all the scripture entries into the appropriate
* chunks, etc. The TeX files that it creates are then used by the LaTeX
* files next time you compile the song book.
*
* The syntax for running the program is:
* songidx input.sxd output.sbx
* or, if you're compiling a scripture index:
* songidx -b bible.can input.sxd output.sbx
*
* The program should compile on unix with
*
* cc *.c -o songidx
*
* On Windows, you'll need to find a C compiler in order to compile it,
* or go to http://songs.sourceforge.net to obtain a Windows self-installer
* with pre-compiled binaries.
