# HOW TO EDIT THIS FILE:
# The "handy ruler" below makes it easier to edit a package description.  Line
# up the first '|' above the ':' following the base package name, and the '|'
# on the right side marks the last column you can put a character in.  You must
# make exactly 11 lines for the formatting to be correct.  It's also
# customary to leave one space after the ':'.

mod_python: mod_python (Apache/Python Integration)
mod_python:
mod_python: Mod_python is an Apache module that embeds the Python interpreter
mod_python: within the server. With mod_python you can write web-based
mod_python: applications in Python that will run many times faster than
mod_python: traditional CGI and will have access to advanced features such as
mod_python: ability to retain database connections and other data between hits
mod_python: and access to Apache internals
