Naming files

[Bardia Kazemi]

I think it is better to name the files and folders as follows

usergrp ==> user_grp
homegrep ===> home_grp

For better readability

[William Kennedy]

I would not do this. Even though the compiler will let you, this is not idiomatic. The language uses the underscore to provide the compiler information such as, _test for a test file and package. Another example is _darwin where you are specifying the OS.

There needs to be a unique package name and I think grp is small and solves the problem.
