CONFIGURATION

SUMMARY

If I run mazer publish releases/wrong_file.tar.gz, mazer will say that I have to specify a path to a collection archive instead of saying that I put in an invalid command. This confuses the user, as it makes them think that they didn't use the proper flags / syntax.

This is a really common thing to happen if you're changing namespaces (which changes the release filename).

STEPS TO REPRODUCE

mazer publish releases/wrong_file.tar.gz

EXPECTED RESULTS

An error message pointing out that the file does not exist.

ACTUAL RESULTS
