Source code in its latest version is hosted on GitHub. It is available as zip or tar.gz archive.
Advantage of cloning from git repo is easy update of source code at a later time.
git clone git://github.com/mimicmod/uhub
Clone to a selected subfolder.
git clone git://github.com/mimicmod/uhub <folder_name>
cd /path/to/uhub/source
git pull
Replace /path/to/uhub/source with a real path where you have cloned the source code (e.g. ~/uhub if you issued the git clone command from your home directory).
