# 
# Basic strategy is that binary figures (that can't be re-generated)
# go in the LECTURE/figs/ subdirectory and get added to the git
# repository.  Everything else lives in the LECTURE/ subdirectory (for
# each LECTURE).
#

#
# Note:  some of the svg images assume that the computer modern tt
# 12-pt font is available.  Install it by copying cmtt12.pfb in
# directory ~/.fonts and running fc-cache.  (cmtt12.pfb is part of
# texlive, you can find it in a place like:
#
#   .../texmf-dist/fonts/type1/public/amsfonts/cm/cmtt12.pfb
