- # has a 0 or 1 value, and the following elements are defined:
- # 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.
- # 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.
