 Only analyze libraries explicitly listed instead of finding all public
-libraries. You can use a regular expression in \fIlibrary-file\fR to match
+libraries. You can use shell patterns used for pathname expansions (see
+the File::Glob manual page for details) in \fIlibrary-file\fR to match
 multiple libraries with a single argument (otherwise you need multiple
 \fB\-e\fR).
