                Create a private fork of a public repository
              
          
    The repository for the assignment is public and Github does not allow the creation of private forks for public repositories.
The correct way of creating a private frok by duplicating the repo is documented here.
For this assignment the commands are:

Create a bare clone of the repository.
(This is temporary and will be removed so just do it wherever.)


git clone --bare git@github.com:usi-systems/easytrace.git

  
## Python3, Pip3, Virtualenv and Virtualenvwrapper Setup
First install pip for Python2. Download the get-pip.py file from https://bootstrap.pypa.io/get-pip.py
$ cd <download location>
$ sudo -H python ./get-pip.py

Installing pip also installs Python3
To run Python3
$ python3

Install pip3 by just executing the same file as in the step above, but this time using Python3
$ sudo -H python3 ./get-pip.py

    PSQL

Magic words:
psql -U postgres
Some interesting flags (to see all, use -h or --help depending on your psql version):

-E: will describe the underlaying queries of the \ commands (cool for learning!)
-l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

    Read-only access, in short

First,
hg clone http://bitbucket.org/durin42/hg-git HGGIT_PATH

Second, in "mercurial.ini" add:
[extensions]
hggit=HGGIT_PATH\hggit
