2972 * structured like the default one.
2973 * See INSTALL for how this works.
2974 * The versioned site_perl directory was introduced in 5.005,
2975 * so that is the lowest possible value.
2976 * Since this can depend on compile time options (such as
2977 * bincompat) it is set by Configure. Other non-default sources
2978 * of potential incompatibility, such as multiplicity, threads,
2979 * debugging, 64bits, sfio, etc., are not checked for currently,
2980 * though in principle we could go snooping around in old
2983 /* PERL_PM_APIVERSION:
2984 * This variable contains the version of the oldest perl
2985 * compatible with the present perl. (That is, pure perl modules
2986 * written for pm_apiversion will still work for the current
2987 * version). perl.c:incpush() and lib/lib.pm will automatically
2988 * search in $sitelib for older directories across major versions
2989 * back to pm_apiversion. This is only useful if you have a perl
2990 * library directory tree structured like the default one. The
2991 * versioned site_perl library was introduced in 5.005, so that's
2992 * the default setting for this variable. It's hard to imagine
2993 * it changing before Perl6. It is included here for symmetry
2994 * with xs_apiveprsion -- the searching algorithms will
2995 * (presumably) be similar.
2996 * See the INSTALL file for how this works.
