Hexyl: A command-line hex viewer
I admit, my first thought on seeing the title was "What's wrong with xxd?"<p>This is nice! I like the colorization a lot -- it's like with source code, you don't realize how much you rely on the colors until you get a new computer and need to download syntax definitions for your editor again. Only feature I <i>really</i> think is missing is line numbers.<p>Nicely done!
