SYNOPSIS
       xsubpp [-v] [-except] [-s pattern] [-prototypes] [-noversioncheck]
       [-nolinenumbers] [-nooptimize] [-typemap typemap] [-output filename]...
       file.xs

DESCRIPTION
       This compiler is typically run by the makefiles created by
       ExtUtils::MakeMaker.

       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 typemap.  It will use
       the following search path to find default typemaps, with the rightmost
       typemap taking precedence.

               ../../../typemap:../../typemap:../typemap:typemap

       It will also use a default typemap installed as "ExtUtils::typemap".

OPTIONS
       Note that the "XSOPT" MakeMaker option may be used to add these options
       to any makefiles generated by MakeMaker.

       -hiertype
            Retains '::' in type names so that C++ hierarchical types can be
            mapped.

       -except
            Adds exception handling stubs to the C code.

       -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.

       -output filename
            Specifies the name of the output file to generate.  If no file is
            specified, output will be written to standard output.

       -v   Prints the xsubpp version number to standard output, then exits.

       -prototypes
            By default xsubpp will not automatically generate prototype code
            for all xsubs. This flag will enable prototypes.

       -noversioncheck
            Disables the run time test that determines if the object file
            (derived from the ".xs" file) and the ".pm" files have the same
            version number.
            declarations.

       -noargtypes
            Disable recognition of ANSI-like descriptions of function
            signature.

       -C++ Currently doesn't do anything at all.  This flag has been a no-op
            for many versions of perl, at least as far back as perl5.003_07.
            It's allowed here for backwards compatibility.

ENVIRONMENT
       No environment variables are used.
