Its the sort of thing you can find out more about in J2EE specs, but in 
Tomcat is doesnt do too much.
Its got the context path in it but (I havent tried it) I think tomcat will 
go with the WebApp name anyway.
So not much... but its Java's way of finding out about a package.
For example in a JAR file its also there and can determine whether a JAR is 
an executable, and I think they also hide digital signatures in there.
On an application server its filled with all sorts of configuration stuff.

One cool thing about it is that Tomcat does not show that folder to a web 
browser... so you can hide stuff in there ;)
but this is normally not done.

Not much... in tomcat ;)  its a little like your appendix - not really 
needed ;)

Tomcat doesnt need too much help to get itself configured... something like 
Glassfish and EAR files... now that needs a lot more help ;)
