-====== Environment Modules ======
+====== Software Modules ======
-[[http://modules.sourceforge.net|Environment Modules]] are designed to manage custom package installations.  Software in our department is all installed to a network filesystem mounted over NFS where each package available is installed to it's own directory.  This allows us to manage a wide range of software across different Linux distributions without users having to deal with any configuration.  We can include different versions of software, letting users choose which they want to use.
+[[http://modules.sourceforge.net|Software Modules]] make it easy for you to use software installed on our Linux systems. We provide a wide range of software across all our servers so that you don't have to install software on your own.  We also offer different versions of software, letting users choose which they want to use.
-===== Available Modules =====
-Please see [[linux_modules:start|Available Modules]] for a listing of available software.
 ===== Using Modules =====
-On any Linux system in our department, you can run ''%%module avail%%'' from your shell to get a list of available software.
