%description
The Environment Modules package is a tool that simplify shell initialization
and lets users easily modify their environment during the session with
modulefiles. Modules-Tcl is the full Tcl rewrite of the Modules package.

Each modulefile contains the information needed to configure the shell for
an application. Once the Modules package is initialized, the environment can
be modified on a per-module basis using the module command which interprets
modulefiles. Typically modulefiles instruct the module command to alter or
set shell environment variables such as PATH, MANPATH, etc. modulefiles may
be shared by many users on a system and users may have their own collection
to supplement or replace the shared modulefiles.

Modules can be loaded and unloaded dynamically and atomically, in an clean
fashion. All popular shells are supported, including bash, ksh, zsh, sh,
csh, tcsh, fish, as well as some scripting languages such as perl and python.

Modules are useful in managing different versions of applications. Modules
can also be bundled into metamodules that will load an entire suite of
different applications.
