# Bulk Lighthouse ticket import from a text file
# Christopher Peplin, peplin@bueda.com
#
# Used this for taking a big Markdown file of tickets we discussed during a
# meeting and importing them all into Lighthouse. No attempt to be flexible,
# just useful in this one case. One ticket title per line, where headers and
# subheaders are used as tags.
#
# Expects the following pseudo-Markdown text file format:
#
#   - Blank lines are ignored
#   - Lines beginning with "# " are parent tags
#   - Lines beginning with "## " are child tags - i.e. tickets will have both that
#      and the parent tag
#   - Lines beginning with "* " are ticket titles to be created in the default
#      milestone
#   - Lines beginning with "!* " are tickets to be put into a "Future Work"
#       milestone (the ID of which is defined at the top of this script)
#
