чаша means "cup" in Bulgarian, and is a play on the larger Python Web Frameworks such as Bottle and Flask. However, instead of targetting the WWW, Chasha targets the Gopher protocol; it includes simple classes for handling Routes, Directories, Images & the like.
Why not? We have Lamson for route-oriented SMTP, and Bottle/Flask/... for Web, may as well have one (or more!) for Gopher.
Addtionally, this allows me to create a non-Digamma reference implementation for some extensions I was thinking of for Gopher+
