# Install Web2Py
cd /home

# Problem faced earlier:
#       Suppose the user enters wrong username, the script would just exit, leaving behind web2py folder in /home.
#       When the user tries to rerun the script , he would get an error message reading something like this
#      "Fatal error , web2py already exists in the path and is not an empty directory"
#       This is caused as we tried to clone the same repository, in the same previous location , where it already is present.

# Fix:
#       Just deleted web2py already present and cloned it later. This solves the issue.
#   A better solution would be to add a check if the dir exists and
#   ask the user if he wants to delete it or not
#rm -rf web2py
