I was searching on how to use some library in my Java code and I came across the GrepCode.com site.
It was great help to find the documentation/code for the library I was using. They only claim to have index for Java, JBoss and Eclipse but the F5 library was there as well.
I installed the Eclipse plugin because that could save some time when searching why I am getting a certain error or why some code is not working as expected.
