=head1 NAME
xsubpp - compiler to convert Perl XS code into C code
=head1 SYNOPSIS
-B<xsubpp> [B<-v>] [B<-C++>] [B<-except>] [B<-s pattern>] [B<-typemap typemap>]... file.xs
+B<xsubpp> [B<-v>] [B<-except>] [B<-s pattern>] [B<-prototypes>] [B<-noversioncheck>] [B<-nolinenumbers>] [B<-nooptimize>] [B<-typemap typemap>] [B<-output filename>]... file.xs
=head1 DESCRIPTION
+This compiler is typically run by the makefiles created by L<ExtUtils::MakeMaker>.
+
I<xsubpp> will compile XS code into C code by embedding the constructs
necessary to let C functions manipulate Perl values and creates the glue
necessary to let Perl access those functions. The compiler uses typemaps to
../../../typemap:../../typemap:../typemap:typemap
+It will also use a default typemap installed as C<ExtUtils::typemap>.
+
=head1 OPTIONS
-=over 5
+Note that the C<XSOPT> MakeMaker option may be used to add these options to
+any makefiles generated by MakeMaker.
-=item B<-C++>
+=over 5
-Adds ``extern "C"'' to the C code.
+=item B<-hiertype>
+Retains '::' in type names so that C++ hierachical types can be mapped.
=item B<-except>
default typemaps. This option may be used multiple times, with the last
typemap having the highest precedence.
-=item B<-v>
-
-Prints the I<xsubpp> version number to standard output, then exits.
