The Shell Toolkit (shtk) is an application toolkit for programmers
writing POSIX-compliant shell scripts.

shtk provides a collection of reusable modules that work on a wide
variety of operating systems and shell interpreters.  The included
modules aid developers in implementing usable and consistent CLI
interfaces, interacting with processes, parsing configuration files
and manipulating higher-level data types among other things.
