Clean up a messy git repo!

Have a git repo with a bunch of junk you want to clean up? Want to get back to a pristine checkout state?

This protip is for you!

1) git clean cleans up "junk" files/directories:

git clean -xfd

(-f to clean up files, -x to clean up ignored files, and -d to clean up directories.)

2) git checkout to get your files back to their committed state:

git checkout -- .

Run this from the root of your repo (note the . in the above command, this means "current directory", but you can use any path you need as appropriate.
