-r spider mpi Finds all modules that have "mpi" in their name.
-r spider 'mpi$ Finds all modules that end with "mpi" in their name.
Handling a collection of modules:
--------------------------------
save | s Save the current list of modules to a user defined "default" collection.
save | s name Save the current list of modules to "name" collection.
reset The same as "restore system"
restore | r Restore modules from the user's "default" or system default.
restore | r name Restore modules from "name" collection.
restore system Restore module state to system defaults.
savelist List of saved collections.
describe | mcc name Describe the contents of a module collection.
disable name Disable (i.e. remove) a collection.

Miscellaneous sub-commands:
---------------------------
is-loaded modulefile return a true status if module is loaded
is-avail modulefile return a true status if module can be loaded
show modulefile show the commands in the module file.
use [-a] path Prepend or Append path to MODULEPATH.
