Ok, I was trying to figure out some of the other Jar's that come with LWJGL. Is the source provided for these in lwjgl-source-2.6.zip and/or info provided for these in lwjgl-docs-2.6.zip? For the Jar's not listed here, I was able to find them in the javadoc and/or source.
AppleJavaExtensions.jar (does anyone use this?)
lzma.jar (compression/decompression obviously)
