+=head1 NAME
+
+rename - renames multiple files
+
+=head1 SYNOPSIS
+
+B<rename> S<[ B<-v> ]> S<[ B<-n> ]> S<[ B<-f> ]> I<perlexpr> S<[ I<files> ]>
+
+=head1 DESCRIPTION
+
+C<rename>
+renames the filenames supplied according to the rule specified as the
+first argument.
+The I<perlexpr> 
+argument is a Perl expression which is expected to modify the C<$_>
+string in Perl for at least some of the filenames specified.
+If a given filename is not modified by the expression, it will not be
+renamed.
+If no filenames are given on the command line, filenames will be read
+via standard input.
+
+For example, to rename all files matching C<*.bak> to strip the extension,
+you might say
+
+	rename 's/\.bak$//' *.bak
+
+To translate uppercase names to lower, you'd use
+
+	rename 'y/A-Z/a-z/' *
+
+=head1 OPTIONS
+
+=over 8
+
+=item B<-v>, B<--verbose>
+
+Verbose: print names of files successfully renamed.
+
+=item B<-n>, B<--no-act>
+
+No Action: show what files would have been renamed.
+
+=item B<-f>, B<--force>
+
+Force: overwrite existing files.
+

+
+=head1 ENVIRONMENT
+
+No environment variables are used.
+
+=head1 AUTHOR
+
+Larry Wall
+
+=head1 SEE ALSO
+
+mv(1), perl(1)
+
+=head1 DIAGNOSTICS
+
+If you give an invalid Perl expression you'll get a syntax error.
+
+=head1 BUGS
+
+The original C<rename> did not check for the existence of target filenames,
+so had to be used with care.  I hope I've fixed that (Robin Barker).
