=========== bag library

bag contains code for many purposes, which I find myself reusing in multiple programs -- so this code must be version-controlled. I use SQLAlchemy and Pyramid a lot.

Documentation is at https://docs.revulo.dev/bag/latest/

The code is at https://github.com/nandoflorestan/bag where you can do your bug reports and pull requests.

This version of bag was published with releaser <https://pypi.python.org/pypi/releaser>_.
