passive.sh is a simple script which does a simple regex search for passive
voice using a regex search on the documentation text.
The script always outputs any passive voice it finds, but only fails on default
if there are more than 3% in the file total. This cutoff can be modified through
the environment variable: RATE_CUTOFF.
