{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).
