The "test-without-rowid" command:
Usage: fossil test-without-rowid FILENAME... Change the Fossil repository FILENAME to make use of the WITHOUT ROWID optimization. FILENAME can also be the configuration database file (~/.fossil or ~/.config/fossil.db) or a local .fslckout or _FOSSIL_ file. The purpose of this command is for testing the WITHOUT ROWID capabilities of SQLite. There is no big advantage to using WITHOUT ROWID in Fossil. Options: --dryrun | -n No changes. Just print what would happen.
