# Overview¶

automan is an open source, Python-based automation framework for numerical computing.

It is designed to automate the drudge work of managing many numerical simulations. As an automation framework it does the following:

• helps you organize your simulations.
• helps you orchestrate running simulations and then post-processing the results from these.
• helps you reuse code for the post processing of your simulation data.
• execute all your simulations and post-processing with one command.

This greatly facilitates reproducibility. Automan is written in pure Python and is easy to install.

This document should help you use automan to improve your productivity. If you are interested in a more detailed article about automan see the automan paper a draft of which is available here: https://arxiv.org/abs/1712.04786

## Installation¶

The easiest way to install automan is with pip:

$pip install automan  If you wish to run the latest version that has not been relesed you may clone the git repository: $ git clone https://github.com/pypr/automan

$cd automan  And then run: $ python setup.py develop


If you just want to run the latest version and do not have git you can do this:

\$ pip install https://github.com/pypr/automan/zipball/master


Once this is done, move on to the next section that provides a gentle tutorial introduction to using automan.
