contributing

• grep me-the in the sources to see how to add a show command
• grep ifcHdlc to see how to add a new interface encapsulation
• take a look on rtrDownload to see an exmaple routing protocol
• find out how to add a new game to the command line interface
• try to solve a puzzle from the todo.txt in the source tree
• in most of the folders there is a class to extend or implment
• your eyes will bleed because of the mix of c, p4 and java
