To validate your TeX, Metafont, and MetaPost executables, run `make triptrap'. This runs the trip, trap, and mptrap "torture tests". See the files `triptrap/tripman.tex', `triptrap/trapman.tex', and `triptrap/mptrap.readme' for detailed information and background on the tests.
The differences between your executables' behavior and the standard values will show up on your terminal. The usual differences (these are all acceptable) are:
Any other differences are trouble. The most common culprit in the past has been compiler bugs, especially when optimizing. See section `TeX or Metafont failing' in Kpathsea.
The files `trip.diffs', `mftrap.diffs', and `mptrap.diffs' in the `triptrap' directory show the standard diffs against the original output. If you diff your diffs against these files, you should come up clean. For example
make trip >&mytrip.diffs diff triptrap/trip.diffs mytrip.diffs
To run the tests separately, use the targets trip, trap,
and mptrap.
To run simple tests for all the programs as well as the torture tests, run `make check'. You can compare the output to the distributed file `tests/check.log' if you like.
