 Spork Omni
 -------------
 Omni lets you combine one of the most common combinations of spork commands (bump, upload & promote or promote --remote) - into one handy shortcut.
 
 As omni is designed for use only in those cases where you want to perform all three of bump, upload and promote at the same time it supports a limited subset of the command line options supported by the individual bump, upload and promote commands.
