## Getting cdist
## Installation
### Preperation
Ensure you have Python 3.x and the **argparse** module installed on
the machine you use to **deploy to the targets**.
#### Archlinux
Archlinux already has python >= 3.2, so you only need to do:
pacman -S python
#### Debian
aptitude install python3 python3-setuptools
easy_install3 argparse
You can clone cdist from git, which gives you the advantage of having
a version control in place for development of your own stuff as well.
### Installation
#### Gentoo
Gentoo only provides python 3.2 in testing packages (http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=3&chap=3).
If you want to ensure nothing breaks you must set back the python version to what was default before.
emerge -av =python-3.2.2 --autounmask-write
emerge -av =python-3.2.2
eselect python list
eselect python list set python3.2
#### Max OS X
Ensure you have port installed and configured (http://www.macports.org/install.php).
port install python32
ln -s /opt/local/bin/python3.2 /opt/local/bin/python3
### Get cdist
You can clone cdist from git, which gives you the advantage of having
a version control in place for development of your own stuff as well.
To install cdist, execute the following commands:
git clone git://git.schottelius.org/cdist
