pythonbrew 1.3.1

Manage python installations in your $HOME

Overview
========

pythonbrew is a program to automate the building and installation of Python in the users $HOME.

pythonbrew is inspired by `perlbrew <http://github.com/gugod/App-perlbrew>`_ and `rvm <https://github.com/wayneeseguin/rvm>`_.

Installation
============

The recommended way to download and install pythonbrew is to run these statements in your shell::

curl -kL http://xrl.us/pythonbrewinstall | bash

After that, pythonbrew installs itself to ~/.pythonbrew.

Please add the following line to the end of your ~/.bashrc::

[[ -s $HOME/.pythonbrew/etc/bashrc ]] && source $HOME/.pythonbrew/etc/bashrc

If you need to install pythonbrew into somewhere else, you can do that by setting a PYTHONBREW_ROOT environment variable::

export PYTHONBREW_ROOT=/path/to/pythonbrew
curl -kLO http://xrl.us/pythonbrewinstall
chmod +x pythonbrewinstall
./pythonbrewinstall

Readline Support
----------------

Python uses a library called `readline` to allow line editing and command history. If you use Python interactively, it is recommended to install both the `readline` library and its headers. Otherwise, the arrow keys won't work in the Python interactive shell.

On Debian and Ubuntu systems, the required package is called `libreadline-dev`. On Fedora, Red Hat, and CentOS, the package is called `readline-devel`. No extra packages are required on Arch or Gentoo.

The `readline` support package must be installed before Python in order to work properly.

For Systemwide(Multi-User) installation
---------------------------------------

If the install script is run as root, pythonbrew will automatically install into /usr/local/pythonbrew.

The pythonbrew will be automatically configured for every user on the system if you install as root.

After installation, where you would normally use `sudo`, non-root users will need to use `sudopybrew`::

sudopybrew install -n -v -j2 2.7.2
