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.
Shelly is originally forked from the Shellish package.
See the shelly-extra package for additional functionality.
An overview is available in the README:
