A *hillariously* kludgey script to convert my pelican markdown files to hugo-parseable YAML format

pelican2yaml.sh

#!/bin/bash

# Save standard output and standard error
exec 3>&1 4>&2
# Redirect standard output to a log file
exec 1>/tmp/stdout.log
# Redirect standard error to a log file

		# This breaks badly if you have a line in your body text that starts with
    # a word followed by a colon. So don't do that! 
    grep '^\w*:\ ' $i > TMPHEAD
