comparison tests/hghave @ 4881:c51c9bc4579d

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Add hghave utility and run-tests.py support. hghave detects system features like symlinks availability at run-time. Tests can be skipped by starting them with: "$TESTDIR/hghave" symlink || exit 80 The 80 exit status triggers hghave output handling by run-tests.py. Also, tests output can be locally patched on the fly to match reference output.
