# Script to split a single text file of Typo posts into multiple text files.
#
# USAGE: Enter the name of the file to split as the first and only arguement
# (extras will be discarded)
#
# INPUT: Single unix file that has each post delimited by 10 #'s (##########)
#
# OUTPUT: a directory "split/" that will have each post as a separte file in
# it.  Filenames are the title of the next line after the 10*#'s but in 
# lowercase, spaces turned into _, /'s turned into -'s, and .txt appended
#
# To get the proper input script/runner may be used as follows:
#
# script/runner -e production "Content.find(:all, :conditions => \
# 'type = \"Article\"').each {|i| puts '##########'; puts i.title;\
# puts ''; puts i.body; puts '' }" > output.txt
