Unit tests for the CALS package. Usage: $ export TEXINPUTS=`pwd`/../dev: $ mkdir tmp $ python support/run_tests.py or, to execute a subset of the tests, $ python support/run_tests.py cell/test_10 Expect that the tests in the directory "visual_tables" fail. Depending on the OS and TeX distro version, the font drawing might look different. 17 Nov 2014: the tests in "visual_tables" are disabled. Probably I need to package the unit testing code as a separate package and publish an article about it.
