hexcat is similar to the popular *nix utility, "hexdump" (it takes a file as an argument, and outputs hex to stdout.)

I wrote this for fun; I was working on a really old machine that didn't have hexdump, so I wrote a tool that did what I wanted.

hexcat outputs hex and text (the latter depending on a command line switch.)

tar.gz file includes source and a man page. Written in C.

Fixed a minor bug that manifested by causing hexcat to dump core...
