java.lang.Objectorg.pz.platypus.CommandTable
public class CommandTable
Table of all supported commands in Platypus. It's implemented using a key consisting of the command root (a String that is long enough to uniquely identify the command). All commands in the Platypus file are looked up in here; Command object that is returned contains all the info for parsing the command.
