mcf-crawler-ui.war file

[hokie]

In the framework build.xml file there is a target called 
"compile-crawler-ui", it has a section commented as "Compile jsp's to 
java" using jasper2 custom defined task. I'm what does it do? Perhaps 
the comment is incorrect, cause I don't see any extra jar or class files 
when I compare my Eclipse-made war to the Manifold 0.1 version.  Eclipse 
does compile your jsps as you edit them, so is this simply making sure 
the jsps are correct and that there is no conversion from jsp to java?
