# This program will do a first take at converting text files in Radeox
# wiki format (what all my labs and such were in previously) to
# Markdown.  Note that this program assumes the cut-and-paste was done
# on a Mac (if done on a different OS, then there are different
# characters that are substituted for the non-ASCII characters).
#
# Most of the replacements are self-explanatory.  The first 6 are:
# - replace long dash with --
# - replace left and right single quote with '
# - replace left and right double quotes with "
# - replace {code} tags with ```
