# unixOnly - 1 means this is a UNIX platform, so it's OK
# to run tests that only work under UNIX.
# macOnly - 1 means this is a Mac platform, so it's OK
# to run tests that only work on Macs.
# pcOnly - 1 means this is a PC platform, so it's OK to
# run tests that only work on PCs.
# unixOrPc - 1 means this is a UNIX or PC platform.
# macOrPc - 1 means this is a Mac or PC platform.
# macOrUnix - 1 means this is a Mac or UNIX platform.
# nonPortable - 1 means this the tests are being running in
# the master Tcl/Tk development environment;
# Some tests are inherently non-portable because
# they depend on things like word length, file system
# configuration, window manager, etc. These tests
# are only run in the main Tcl development directory
# where the configuration is well known. The presence
# of the file "doAllTests" in this directory indicates
# that it is safe to run non-portable tests.
# knownBug - The test is known to fail and the bug is not yet
# fixed. The test will be run only if the file
# "doBuggyTests" exists (intended for Tcl dev. group
# internal use only).
# fonts - 1 means that this platform uses fonts with
# well-know geometries, so it is safe to run
# tests that depend on particular font sizes.

# name - Name of test, in the form foo-1.2.
# description - Short textual description of the test, to
# help humans understand what it does.
# constraints - A list of one or more keywords, each of
# which must be the name of an element in
# the array "testConfig". If any of these
# elements is zero, the test is skipped.
# This argument may be omitted.
# script - Script to run to carry out the test. It must
# return a result that can be checked for
# correctness.
# answer - Expected result from script.
