I could try to find all the pieces, but given that it is wired together out of the pieces of 4 different unrelated projects symlinked across different computers, some of which no longer exist, something will probably be missing, and all of it is completely illegible unless you really enjoy code written as an exercise in being horrible. You sure you want it?
Actually, I'm not sure I can find all of it. Some of that was part of the PMBD servers, which definitely aren't around anymore and have been archived in some giant tgz file that is impractical to open as there is not enough space on anything but a replacement server to unpack it.
Yeah, I'm fine with horrible/incomplete source code.
Also, you don't need to extract entire archives, you could do this:
List the contents and find the file you want:
tar -ztvf file.tar.gz
Now extract that file:
tar -zxvf file.tar.gz nameoffileintargz
