 Guide for Creating Virtual Environments for Python
 
 Reason
 
 To load modules and packages that are only relevant to you or
 to develop and test new modules and packages not ready for general use.
 
 
 How To
 
 1) Generate a virtual environment
 
-Generate a blank virtual environment: 
+Generate a blank virtual environment using python2.7: 
 
-virtualenv ENV
+virtualenv -p python2.7 ENV
 
 Generate a snapshot environment with base packages(BeautifulSoup==3.2.0 and MySQL-python==1.2.3) used for ENCODE:
 
-python ~/kent/python/ucsc_virtualenv.py ENV
+python ~/kent/python/ucsc_virtualenv.py -p python2.7 ENV
 
 2) Switch to use virtual environement
 
 Bash:
 
 source ENV/bin/activate
 
 C-Shell:
 
 source ENV/bin/activate.csh
 
 3) Load packages and modules
 
 Third-Party:
 
 pip install <package name>
 
 pip is an easy_install replacement. For more information visit: http://pypi.python.org/pypi/pip
 
 Internal packages (use setup.py located in package directory e.g. kent/python/lib):
 
 python setup.py install
 
 4) Deactivate use of virtual environment
