Python script to extract all of the svn:externals in a SVN path recursively.

externals.py

"""
This script is adapted from http://stackoverflow.com/a/10286163/2464295 but without the
multi threading factor of it.
Usage: `externals.py https://svn-server/repository`

Do note that the script is excluding src and hidden directories that starts with dot. Just modify the file
as it's not parameterized.

If you want this script to run faster, SSH to the SVN server and use file protocol.
Usage: `externals.py file:///svn/repository`
