## Install dropbox
## `cd ~ && wget -O - "https://www.dropbox.com/download?plat=lnx.x86_64" | tar xzf -`
## This basically creates a folder `~/.dropbox-dist`
## Initiate `~/.dropbox-dist/dropboxd` and it will ask you some questions the first 
## time you run it.

			# This is how you define optional params
