- Generate a composed mosaic of all functions to facilitate printing
  
  This could be done using ImageMagick, for example:

  cd src/data/functions ; \
    montage -label %f [0-9].png [0-9][0-9].png all.jpg

  cd src/data/functions ; \
    montage -label %f [0-9]-detail.png [0-9][0-9]-detail.png all-detail.jpg

  And then convert to PDF.

  Ideally, the label of the card would be the name of the function
