Shell Tool of the week: rlwrap

This week's "shell tool of the week" (and as such first of it's kind) is rlwrap. rlwrap calls another interactive program but channels all of the input through the readline library (the notorious piece of software which refuses to become L-GPL, for a reason), giving you extensive command-line editing capabilities even for programs which are just getting their input via gets (for example, ftp).

If it hadn't been done, I would've done it!

Addendum: I just found out that rlwrap actually stores different histories for each program it is used with!
