Makefile

#################################################
# Makefile for bepress-pythonz deb package
# 
# pythonz (https://github.com/saghul/pythonz) is the python equivalent of perlbrew
# (there is also a 'pythonbrew' package, but it is unmaintained, which is why
# pythonz was forked from pythonbrew)
# 
# This package contains an installed copy of pythonz with a pre-compiled (for
# amd64) copy of python 3.3.2.  It installs into /opt/bepress/pythonz.
# Python 3.3.2 ends up in /opt/bepress/pythonz/pythons/CPython-3.3.2
# You can create a virtualenv using this python by running 
# /opt/bepress/pythonz/pythons/CPython-3.3.2/bin/pyvenv
# (note that the virtualenv module that ships with python 3.3 does not set up
# easy_install or pip for you.  To install pip, you first need to download and
# run https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py which 
# installs easy_install.  Then, run 'easy_install pip' to install pip
# 
# To build the package, just type "make". It'll tell you it created a filename
# something like "bepress-setuid-svstat-1.20110524-4_all.deb".
# 
# A Debian package consists of three files in an 'ar' archive:
# 
#    - debian-binary
#    - data.tar.gz
#    - control.tar.gz 
#
# The first is just the number "2.0".  
#
# The second is the contents of the "data", so if you have data/var/lib/foo it'll 
# be installed into /var/lib/foo.  
#
# The third are the files in control/: one file called "control" and then any/all of the four
# maintainer scripts preinst, postinst, prerm, postrm as described here: 
# http://www.debian.org/doc/debian-policy/ch-maintainerscripts.html
