+/* 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.
