# converter.py -- convert Radio Userland posts to (other)
#
# Originally from http://www.aaronsw.com/weblog/000159
# (Aaron Swartz -- Radio to MT)
#
# Hacked on by Brian St. Pierre for Radio to blosxom
#  - don't add <p/> to post bodies (I've been careful)
#  - grab title
#  - output title, body in "blosxom format"
#  - create convert_post() function
