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.
