## Not going to cover abbreviations, since this is for completions anyway :D
## rebar allows you to abbreviate the command to run:
## $ rebar co           # same as rebar compile
## $ rebar eu           # same as rebar eunit
## $ rebar g-d          # same as rebar get-deps
## $ rebar x eu         # same as rebar xref eunit
## $ rebar l-d          # same as rebar list-deps
## $ rebar l-d l-t      # same as rebar list-deps list-templates
## $ rebar list-d l-te  # same as rebar list-deps list-templates
##
## Core command line options:
##   apps=app1,app2 (specify apps to process)
##   skip_apps=app1,app2 (specify apps to skip)
