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

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 tcl, perl, python, ruby, cmake and r.

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.
