Can't get this to work without changing the code. Semver is not callable

[wadlo]

Trying to use this, and it's failing saying it can't run semver as a function. I tracked it down to this code:

      if (version) {
        programInfo.version = semver(version);
      }

If I change it to

      if (version) {
        programInfo.version = new semver.SemVer(version);
      }

it does work.

I'm pretty new to npm and node, so I'm probably doing something wrong...
