226fb12b70Safresh1Sets up various bits of previously global state
236fb12b70Safresh1(formerly ExtUtils::ParseXS package variables)
246fb12b70Safresh1for eval'ing output typemap code that may refer to these
256fb12b70Safresh1variables.

296fb12b70Safresh1Not all these variables are necessarily considered "public" wrt. use in

896fb12b70Safresh1
906fb12b70Safresh1Eventually, with better documentation and possible some cleanup,
916fb12b70Safresh1this could be part of C<ExtUtils::Typemaps>.
