== Installation instructions ==

=== Short instructions ===

'''Step 1.''' To install the experimental patches provided by Sage-combinat, you first need to install Sage. You have two options.

    1. Binary installation (takes less time; only option on Windows; only works if a binary exists for your system):

        * Download a binary distribution ''for your system'' from [[http://sagemath.org/download.html]] and follow the installation instructions on that page.

    2. Source installation (recommended, but time-consuming; works for Linux and OSX as long as you have a compilier):

        * Download the source code from [[http://sagemath.org/download-source.html]] and follow the installation instructions on that page.

'''Step 2.''' Install the Sage-Combinat patches by running the following command ''inside the sage directory'':
    {{{
./sage -combinat install
    }}}
(note: this may require Sage 4.1 which will be out shortly).
If this step fails, please send an email to the {{{sage-combinat-devel}}} mailing list below with the error message.

=== Long instructions ===

Sage-Combinat

Sage-Combinat is a software project whose mission is: to improve the open source mathematical system Sage as an extensible toolbox for computer exploration in (algebraic) combinatorics, and foster code sharing between researchers in this area.

In practice, Sage-combinat is a collection of experimental patches (i.e. extensions) on top of Sage, developed by a community of researchers. The intent is that most of those patches get eventually integrated into Sage as soon as they are mature enough, with a typical short life-cycle of a few weeks. In other words: just install Sage, and you will benefit from all the Sage-combinat development, except for the latest bleeding edge features.
