Sandbox/Migration example

Here is an example of what you might see (subject to change as the utility evolves):

$ modules-migrate  
This application will help you adapt your environment-modules customizations to
Carbon's 2016 module naming scheme.

Your module commands in .bashrc will be deactivated (commented out) and instead
placed into two similar files .modules-el5-legacy and .modules-el6, for use by different
operating system releases.

This helper application will modify your files in a fairly simplistic manner.
You will have an opportunity to manually review and refine the edits.
