Class that holds the files that will be stored in the jar file. The #files attribute contains a hash of pathnames inside the jar file to their contents. Contents can be one of:
nil representing a directory entry
Any object responding to read representing an in-memory blob
A String filename pointing to a file on disk
Add init.rb file to the war file.
