How to compress PDF using ghostscript

As a developer, it bothers me when someone sends me a large pdf file compared to the number of pages. Recently, I recieved a 12MB scanned document for just one letter-sized page... so I got to googlin, like I usually do, and found ghostscript!

to learn more abot ghostscript (gs): https://www.ghostscript.com/

What we are interested in, is the gs command line tool, which provides many options for manipulating PDF, but we are interested in compressign those large PDF's into small yet legible documents.

This is about how to split a GitHub pull request, following a real in-the-wild example.

So it happened that I once wanted to fix a bug (#832) on the shelljs repository.

I forked the repository, cloned it and created a new branch called ln-directory-dest. I fixed the bug, created a pull request, and implemented initial review feedback.

At this point, I had added the commits A, B, C, D, E and [F](https://github.com/Loilo/shelljs/commit/946ab48bf5cf9c8aac03407

	# many examples exist on StackOverflow, etc..

	# Note: you'll need python-xlib, python-gtk
	# sudo apt-get install python-xlib python-gtk2
	#

	import sys
	import os

	# All this is implemented (plus bugfixes!) in the ggnewscale package:

	# If you have any issues, I prefer it if you send them as issues here:
