=head1 SYNOPSIS
-B<xsubpp> [B<-v>] [B<-C++>] [B<-except>] [B<-s pattern>] [B<-noprototypes>] [B<-typemap typemap>]... file.xs
+B<xsubpp> [B<-v>] [B<-C++>] [B<-except>] [B<-s pattern>] [B<-prototypes>] [B<-noversioncheck>] [B<-typemap typemap>]... file.xs
=head1 DESCRIPTION
Prints the I<xsubpp> version number to standard output, then exits.
-=item B<-noprototypes>
+=item B<-prototypes>
+By default I<xsubpp> will not automatically generate prototype code for
+all xsubs. This flag will enable prototypes.
+
+=item B<-noversioncheck>
+
+Disables the run time test that determines if the object file (derived
+from the C<.xs> file) and the C<.pm> files have the same version
+number.
