"""
WebLab-Deusto setup script. Running:

   python setup.py install 
   
will install the whole WebLab-Deusto system (a virtualenv is recommended).

The pure Python project is stored in server/src. In client you may find a 
pure Java project for the client (developed with Google Web Toolkit). We 
keep this setup.py here (which actually calls the server/src/setup.py
script) so as to support:

   pip install git+https://github.com/weblabdeusto/weblabdeusto.git

However, some dirty things are required for this (given that this project
does not follow the Python convention of using the root project directly),
such as moving the pip-egg-info directory, etc.

# If it has been created, we move it to the server/src directory, and then return
# it at the end of the script.
