Software modules
To manage multiple software packages, including different versions of the same software, ICDS uses the Lmod Environment Module System to prevent conflicts and compartmentalize software and compiler usage.
Users can use the module command combined with different subcommands to access and use
pre-installed software.

user environment when a module is loaded, including changes to environmental variables such as
$PATH and $LD_LIBRARY_PATH.
