Bar: Not so simple modulefile example
Version $version
Threading Model: $threadstr

This is a more complicated example of code reuse in modulefiles.
We have multiple versions of bar on the system, and each version
comes with multiple variants for different threading support modules.
Plus we assume that the env var BAR_LICENSE_FILE needs to be set
differently depending on the bar version.

Using license file: $licensefile
