corrupted archive.tar.gz file

This looks like something I'd like to try. I too have dealt with issues stemming from trying to setup a development environment locally with Sublime Text 3. It is not easy to keep it consistent and match production.

When I try to run the wget command in the install script, the archive.tar.gz file it downloads appears to be corrupt. The next command that runs, tar, can't extract the archived files. It errors with:

gzip: stdin: not in gzip format

I would also like to know if this code is open source and if so, which license does it have before I use it? Thank you.
