sage-combinat is a collection of experimental patches #link#
(i.e. extensions) on top of sage, developed by
a community in algebraic combinatorics. Its main purpose is to improve
sage as an extensible toolbox for computer exploration, and foster
code sharing between researchers in this area. The intent is that most
of those patches eventually will get integrated into sage as soon as
they are mature enough, with a typical short life-cycle of a few

== 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 requires Sage 4.1 which will be out shortly.
If this step fails, then send an email to the {{{sage-combinat-devel}}} mailing list below with the error message.

    Sage-combinat was born as a partial port of [[http://mupad-combinat.sf.net|MuPAD-Combinat]]. After months of discussions and experiments, an enthusiastic consensus emerged in the MuPAD-Combinat community to join Sage. Sage-combinat henceforth became the natural successor of {{{MuPAD-Combinat}}}.

   The transition is a massive investment: seven years of hard work to port over! However a lot of experience was gained since 2000, and most of the design is now pretty clear. By sharing the work the transition will hopefuly be relatively quick.

Sage-Combinat

Sage-Combinat is a software project whose mission statement 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.
