This git hook checks for the existence of gender pronouns in the commit message and aborts the commit if it finds one

README

Using gender pronouns in your git messages can put you in difficult situations.
Refer https://github.com/joyent/libuv/pull/1015 for drama caused by this in nodejs community. 
If you ever thought what power does a pronoun in a commit message, go read https://www.joyent.com/blog/the-power-of-a-pronoun

So its best if you can avoid them while composing the commit message. Since 'To err is human', you need a 
gaurdian to make sure that you don't have gender pronouns, hence this script.

You need to place the Gender Pronoun check file contents inside `.git/hooks/commit-msg` file. 

There are the pronouns considered for validatomg ['he', 'him', 'his', 'himself', 'she', 'her', 'hers', 'herself']

After adding this, any attempt to use gender pronouns will result in failure of git commit.
