WARNING: DO NOT USE THIS IN ANY PRODUCTION UNTIL VERSION 1.0 IS ACTUALLY
RELEASED. YOU HAVE BEEN WARNED!

dscip: Dead Simple Continuous Integration POSIX
================================================================================
This is a script/daemon that scans a git repo for changes, and runs commands
automatically. It's meant to be a dead simple alternative to services like
Gitlab-ci and Jenkins. This script was also made to be as POSIX compliant as
possible, so it should run on basically every platform with a POSIX shell.

Refer to the docs folder for how to use DSCIP.

1.0 will probably be released once I'm sure most if not all bugs are gone.
Which is swiftly approaching.
