Even though MS/DOS is mostly gone, FAT file systems still exist.  Also,
I think that the standard for CD Roms restricts file-name length and case
(but I may be wrong).  Another problem is that HFS+ file systems in
MacOS X are case insensitive, which introduces more limits on programs.

Using a fixed mapping between module names and filenames is a limitation
that we do not need.
