Shake.hs is a more powerful Makefile, providing a number of commands
|
|
for performing useful tasks. Compiling this script is suggested, so that
|
|
it runs quicker and will not be affected eg when exploring old code versions.
|

Shake notes:

wishlist:
|

just one shake import
|
|
wildcards in phony rules
|
|
multiple individually accessible wildcards

not having to write :: Action ExitCode after a non-final cmd
