I used to have many programs which you will now find in Perl also available in C. However, I was not updating them anymore, and they were becoming incompatible with other things I had. So, for programs where I have duplicates, I now only make available the Perl versions. Ask me for a C version if you want. I might be able to make it work.
Also, some of my TeX packages have included in them programs. In this case I have chosen to include the Perl versions.
Please feel free to email me at andrew at mast.queensu.ca if you have questions about any of these programs.
