[PYTHON] Command line tool to put .gitkeep in an empty directory

As you move from Subversion to Git, you have to remember to add an empty directory to your repository. Git doesn't version control empty directories, so you'll need to put some files there. Some files are `.gitignore``` and ```empty```, but I personally try to put `.gitkeep``` in a Rails style.

Basically, you can run find. -Type d -name .git -prune -o -type d -empty -exec touch {} /. Gitkeep \;` ``. The tool I made this time is optional, such as the function to check which directory is empty before placing `` .gitkeep and the ability to specify the `` `.gitkeep``` part of this command. It is an added function.

How to use

List empty directories:

cd git-repo
git-empty-dir list

Place .gitkeep in an empty directory:

cd git-repo
git-empty-dir keep

There are other options such as `--dir``` and `--keeper```.

$ git-empty-dir keep --help
usage: git-empty-dir keep [-h] [--dir DIR] [--keeper KEEPER]

optional arguments:
  -h, --help       show this help message and exit
  --dir DIR        path to git directory
  --keeper KEEPER  dummy file name. Default is ".gitkeep"

Python's argparse is useful!
