+=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<-prototypes>] [B<-noversioncheck>] [B<-nolinenumbers>] [B<-nooptimize>] [B<-typemap typemap>] ... 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
+determine how to map C function parameters and variables to Perl values.
+
+The compiler will search for typemap files called I<typemap>. It will use
+the following search path to find default typemaps, with the rightmost
+typemap taking precedence.
+
+ ../../../typemap:../../typemap:../typemap:typemap
+
+=head1 OPTIONS
+
+Note that the C<XSOPT> MakeMaker option may be used to add these options to
+any makefiles generated by MakeMaker.
+
+=over 5
+
+=item B<-C++>
+
+Adds ``extern "C"'' to the C code.
+
+=item B<-except>
+
+Adds exception handling stubs to the C code.
+
+=item B<-typemap typemap>
+
+Indicates that a user-supplied typemap should take precedence over the
+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.
+
+=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.
+
+=item B<-nolinenumbers>
+
+Prevents the inclusion of `#line' directives in the output.
+
+=item B<-nooptimize>
+
+Disables certain optimizations. The only optimization that is currently
+affected is the use of I<target>s by the output C code (see L<perlguts>).
+This may significantly slow down the generated code, but this is the way
+B<xsubpp> of 5.005 and earlier operated.
+
+=item B<-noinout>
+
+Disable recognition of C<IN>, C<OUT_LIST> and C<INOUT_LIST> declarations.
+
+=item B<-noargtypes>
+
+Disable recognition of ANSI-like descriptions of function signature.
