shelly-1.12.1: shell-like (systems) programming in Haskell

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: https://github.com/gregwebs/Shelly.hs/blob/master/README.md
