Easily create Dropbox remotes for your Git repositories.

readme.txt

Background:

I don't have a paid GitHub account, so I use Dropbox to backup my repositories privately.  
What's annoying is that every time I create a "dropbox" remote I go through the same time-consuming steps.  
Well I'm done with that, homeboy.  Now it's as easy as:

>>>>>>>>>>>>>

$ pwd
/usr/local/apps/db-cache.git
$ git dropbox add-remote
Initialized empty Git repository in /home/jhuttner/Dropbox/git-repos/db-cache.git/
$ git push dropbox master 


<<<<<<<<<<<<<

Installation instructions:

1.  Install Dropbox for Linux, or whatever you are using.  I recommend the command line install: https://www.dropbox.com/install?os=lnx

2.  Start the Dropbox daemon: $ ~/.dropbox-dist/dropboxd

3.  Paste the commands from run.sh (below) into your Terminal.  In a nutshell, they:
    - Clone this gist
    - Make the Python file executable
    - Setup a symlink in ~/bin
    - Create a "git dropbox" alias to call the Python file.

    NOTE that ~/bin must be in your PATH for this to all work.

import subprocess

Working great.
