If none of the following actions is specified, -print is assumed
-print Print file name
-print0 Print file name, NUL terminated
-exec CMD ARG ; Run CMD with all instances of {} replaced by
file name. Fails if CMD exits with nonzero
-exec CMD ARG + Run CMD with {} replaced by list of file names
-delete Delete current file/directory. Turns on -depth option
-empty Match empty file/directory.
-quit Exit
"""
The above is wrong: -empty does not "turn off" implicit -print.
IOW: -empty help text should be above this block.
