Which is right?
lein new test-project
lein new test_project

What is confusing me is that it seems like for filenames and directories, the convention is to use underscores in place of hyphens, while within clojure code itself, hyphens are used.  

If this is true, it would seem to suggest the second way is the right way.

However, although all the files and directories follow the underscores instead of hyphens approach when using the second way, the project name in the code does the same.  In other words, I get (defproject test_project (etc.)) in project.clj and (ns test_project.core) in core.clj.  Is this right?  Should it be (defproject test-project) and/or (ns test-project.core) instead?
