# This script converts markdown into html, to be used with vimwiki's
# "customwiki2html" option.  Experiment with the two proposed methods by
# commenting / uncommenting the relevant lines below.
#
#   NEW!  An alternative converter was developed by Jason6Anderson, and can
#   be located at https://github.com/vimwiki-backup/vimwiki/issues/384
#
#
# To use this script, you must have the Discount converter installed.
#
#   http://www.pell.portland.or.us/~orc/Code/discount/
#
# To verify your installation, check that the commands markdown and mkd2html,
# are on your path.
#
# Also verify that this file is executable.
#
# Then, in your .vimrc file, set:
#
#   g:vimwiki_custom_wiki2html=$HOME.'/.vim/autoload/vimwiki/customwiki2html.sh'
#
# On your next restart, Vimwiki will run this script instead of using the
# internal wiki2html converter.
