Convert a directory of Notational Velocity notes to a single Emacs org-mode file

# Convert a directory of Notational Velocity notes to a single file of
# Emacs org-mode notes. Must be run from within the directory to be
# converted. Each entry in the resulting org file will be a 2nd-level
# entry ("** ...") whose title is derived from the filename and whose
# body contains the file contents. Output is written to stdout. '*' at
# the beginning of a line will be converted to '-' to avoid being
# confused with an org-mode headline.
