There was a time when everything that managed content in some way was being renamed "CMS" in order to fit into a category that was selling at the time. Fitting sometimes very oddly shaped things into the category was common, and I think a lot of cool software got needlessly mangled (TWiki also went off in a lot of weird, occasionally "CMS like", directions to satisfy some sort of enterprise dream that hurt its usability in a lot of ways).
It wasn't great, though for 2000-era mod_perl code, it was decent. It had a lot of solid ideas that predated the Rails-wave of web development, but they could have used a lot more polish.
That's good to hear. It (and a python-based rewrite) was one of the first software projects I looked at and had a chance to mess with when I began to learn to code.
