build_python

#!/bin/bash

# TEST_VERSIONS: 2.7.12 3.5.2

### Description
# This script uses fpm to build and package Python.
# In order to not interfere with the system version of Python, I
# opted to call this package 'python-local'. Dependencies for
# python-local are based on the packages used to build python-local
# and the existing Debian Python dependency tree.

# Required Environment Variables:
#   - BUILD_VERSION
#   - BUILD_ITERATION
#   - BUILD_OUTPUT_DIR

# Example Usage:
#   The following command will create /tmp/python-local-3.5.2-1.deb
#     $ BUILD_VERSION=3.5.2 BUILD_ITERATION=1 BUILD_OUTPUT_DIR=/tmp build_python
