# Important tools used in the IPSL climate modeling framework #

The following tools are used for all steps from setup to post processing. They must be available on the [wiki:DocBenv computing machine] (except [#Forge forge]).

The [wiki:DocBenvEcommonfiles common] account configuration files allow you to access the proper version of the tools (e.g. {{{module load}}}).
