SelFile.pm is a file select Perl-Tk module.  It runs under
 Perl version 5.001-l (dash el) and Perl Tk version b7 .

 If you do not wish to install it under the usual Tk distribution,
 and you have a personal Perl library such as /u/someone/lib/MyPerl,
 then this can be installed in the directory /u/someone/lib/MyPerl/Tk
 You would then need to set the environmental variable PERL5LIB.
 PERL5LIB=/u/someone/lib/MyPerl ; export PERL5LIB
 (Example show above is Bourne, Korn style.  For more than one
 directory, the directory names should be separated by a colon.)

 FS_example.pl is a wrapper for using the Perl module with C.
 The first lines needs to be modified for your site, for example,
 #!/usr/local/bin/perl5
 It seems to work without starting MainLoop -- which is commented-out
 in the code.

 fs_example.c is not a complete C program, but just a code fragment
 showing how FS_example.pl could be used with a C program.
