# This program looks in the directories where the generated .ly files #
# and the generated pdf images are stored. #
# If it finds that there are missing pdfs it will recompile them #
# using LilyPond. #
# #
# The main purpose is to allow the creation of pdf images of glyphs #
# that already have been processed to LaTeX commands but whose PDF #
# files have been lost. #
# The other purpose is to update the set of PDF files to a new version #
# of Emmentaler or LilyPond without touching the definitions. #
