# - "make slides" creates lecture slides
# - "make notes" creates slides with notes in the A4 format
#
# For correct links and PDF bookmarks it is necessary to run make twice.
#
# Do not edit m4 files, those are automatically created during the document
# generation.
#
# The 'spellcheck' target requires the aspell program.
