debian/tests/control is generated with:

 cd tests
 for t in */*.sh; do
   printf "Test-Command: debian/tests/run %s\n\n" "$t"
 done > ../debian/tests/control

Then the tests that require special binaries are annotated or
commented out manually.  To update the list of tests, use "git gui" to
index the new ones, then revert unwanted changes to manual
modifications.
