Private Module Example
The modules package allows you to pick which software packages and version you wish to use. It has the advanatages in easily handling PATH, MANPATH and other important variables for you as well as making rolling out new version a much simplier process.
Users can make their own module files, privatemodules must go in
/home/username/privatemodules/
There is a structure to the layout of the privatemodules folder. Normally a software package, is given a folder inside privatemodules and the individual modulefiles are given versions as names.
Example privatemodules Folder
In this case a folder openmpi/ has two files, 1.2.5-intel 1.3.2-gcc representing two versions of the same module.
openmpi/1.2.5-intel
openmpi/1.3.2-gcc
Example module file
Read each line of the example carefully, the first line (#%Module1.0) is required to work,
#%Module1.0#######################################################################
## modules modulefile

#this is a comment, white space is allowed
#output on module help modulefile

puts stderr "\tenvironment variables."
puts stderr "\n\tVersion $version\n"
}
