Yet another Argument parsing pacKage
(a.k.a. an exercise in yak shaving.)

What does it do?

It supports simple POSIX-like command-line argument parsing for Tcl applications.

How do I use it?

set argv "-a --param 5"
yak parse "-a|--arg -o -p|--param=TEST" $argv
puts [yak get -a]       # true
puts [yak get --arg]    # true
puts [yak get --param]  # 5
puts [yak get -o]       # false
puts [yak get --fancy]  # false

Basically, use | to separate short and long argument forms, and = to indicate that it's a value argument and not a flag.
