/* PERL_XS_APIVERSION:
 *      This variable contains the version of the oldest perl binary
 *      compatible with the present perl.  perl.c:incpush() and
 *      lib/lib.pm will automatically search in $sitearch for older
 *      directories across major versions back to xs_apiversion.
 *      This is only useful if you have a perl library directory tree
 *      structured like the default one.
 *      See INSTALL for how this works.
 *      The versioned site_perl directory was introduced in 5.005,
 *      so that is the lowest possible value.
 *      Since this can depend on compile time options (such as
 *      bincompat) it is set by Configure.  Other non-default sources
 *      of potential incompatibility, such as multiplicity, threads,
 *      debugging, 64bits, sfio, etc., are not checked for currently,
 *      though in principle we could go snooping around in old
 *      Config.pm files.

/* PERL_PM_APIVERSION:
 *      This variable contains the version of the oldest perl
 *      compatible with the present perl.  (That is, pure perl modules
 *      written for pm_apiversion will still work for the current
 *      version).  perl.c:incpush() and lib/lib.pm will automatically
 *      search in $sitelib for older directories across major versions
 *      back to pm_apiversion.  This is only useful if you have a perl
 *      library directory tree structured like the default one.  The
 *      versioned site_perl library was introduced in 5.005, so that's
 *      the default setting for this variable.  It's hard to imagine
 *      it changing before Perl6.  It is included here for symmetry
 *      with xs_apiveprsion -- the searching algorithms will
 *      (presumably) be similar.
 *      See the INSTALL file for how this works.
