How to Install Improved "Text Along Path" Script?

[TechnicGeek]

Hello,

I wanted to install Text Along Path:
http://registry.gimp.org/node/26168

However all I see are .ZIP and .PY files and it seems that PY stands for Python?
If so, I heard such files need to be compiled and I have no idea how to.
I just want to install this script because it claims that text along path function
will work better with it.

Thanks.
