# returns a non-empty set); used outside, they simply output informational

# The heuristic is to find files that do not contain a line
# matchines /^tg:/, minus the series file. If any such files
# are found, an error occurs. Otherwise, the directory is
# removed. This means that edits to the series file are

# directory in doing so. Yes, *force*-fully. WHAM!
