 This project takes inspiration from [gitless](http://gitless.com/) and [legit](https://github.com/kennethreitz/legit), and is
 influenced by this [blog post](http://www.saintsjd.com/2012/01/a-better-ui-for-git/) and this [fantastic diatribe](http://stevebennett.me/2012/02/24/10-things-i-hate-about-git).

+### Why?
+I started this project because `git log --no-pager` gives an error. Apparently I wanted `git --no-pager log`. This was the last straw.
+*So I decided to "fix" the git CLI.*
+
+EDIT: Even better example of inanity of git CLI: To get the SHA reference of HEAD, do you use `git show-ref HEAD --abbrev --hash` or `git rev-parse --short HEAD`?
+
+ * Why are they different results?
+ * Why does `show-ref` use `--abbrev` but `rev-parse` use `--short`?
+ * Why are the options _after_ `HEAD` in `show-ref` but _before_ `HEAD` in `rev-parse`?
+ * I leave answering these questions as an exercise to the reader.

 get clone %PATH% | %PATH% can be a normal url. Paths like "username/repo" will be expanded assuming a Github. Paths with just "repo" will expand to a Github url, if your Github username is stored in git config.

 ### TODO
 Now that I've added tab completion, I think "stage" and "status" are too similar.
