Sandbox/Migration example

Here is an example of what you might see:

$ modules-migrate  

This application will help you adapt your environment-modules customizations to
Carbon's naming scheme 2 (introduced in 2016).

Your module commands will be _removed_ from .bashrc and instead placed into two similar
files .modules-1 and .modules-2, for use by different operating system releases.

NOTE: The file text manipulation done here is fairly basic. You will have
opportunity to review and edit the results.
