 .SH "DESCRIPTION"
 
 With a single directory argument, \fBfinddup\fP prints the duplicated
-files found in it. With two directories, it prints either the files
-common to both DIR1 and DIR2, or with the `not:' prefix, the ones
-present in DIR1 and not in DIR2. The and: prefix is assumed by default
-and necessary only if you have a directory name starting with `not:'.

 This command compares files by first comparing their sizes, hence goes
 reasonably fast.
 
-When looking for identical files, \fBfinddup\fP associates by default
-a group ID to every content, and prints it along the file names. Use
-the \fB-g\fP to switch it off.
