{file,In,Out,true} = render with mustache
{file,In,Out,false} = do not render with mustache (leave as-is)

old-form {file,In,Out} is equivalent to {file,In,Out,true}

eg.  rebar eunit              -- runs all tests in all modules
     rebar eunit suite=foo    -- only runs tests in foo.erl/foo_tests.erl

Added an entry to .hgignore to avoid .swp files (created by VIM).
