PyBlosxom is a lightweight file-based weblog system. The project started as a Python clone of Blosxom but has since evolved into a beast of its own. PyBlosxom focuses on three things: simplicity, extensibility, and community.
simplicity - PyBlosxom uses the file system for all its data storage. Because of this you can use whatever existing editor, scripts and tools you want to create, update and manipulate entries and other blog data.
extensibility - PyBlosxom has a plugin framework allowing you to build plugins in Python to augment and change PyBlosxom's default behavior.
community - There are hundreds of PyBlosxom users out there all of whom have different needs. PyBlosxom is used on a variety of operating systems in a variety of environments. The pyblosxom users list shares their experiences, plugins, and expertise. The pyblosxom devel list shares their ideas for changes, patches and plugins.
PyBlosxom can run in CGI environments, under Paste, and as a WSGI application.
As such, PyBlosxom is a pretty straight-forward system that allows you to do the things you need to do without building everything from scratch.
