Shelly provides convenient systems programming in Haskell,
similar in spirit to POSIX shells. Shelly:
* is aimed at convenience and getting things done rather than
being a demonstration of elegance.
* has detailed and useful error messages
* maintains its own environment, making it thread-safe.
* is modern, using Text and system-filepath/system-fileio
Shelly is originally forked from the Shellish package.
See the shelly-extra package for additional functionality.
