make all will execute unit tests followed by the clipping tests. Generating
PNG images must be run second with make png (see below).
Most core functionality is tested with unit tests in units.tcl. Simply
execute the script to run the tests.
The unit tests utilize a testing framework - unitt - provided in the scripts/
directory.
Clipping tests are all standalone scripts beginning with t. They require Tk
in order to draw the results. They also use a utility proc defined in
scripts/testutils.tcl, which is used to simplify the test code.
Results are shown on in a GUI and saved to Postscript files in the results/
directory. The postscript files can be converted to PNG. make png uses
Ghostscript to convert all PS files to PNG format.
