3052 /* PERL_PM_APIVERSION:
3053 * This variable contains the version of the oldest perl
3054 * compatible with the present perl. (That is, pure perl modules
3055 * written for pm_apiversion will still work for the current
3056 * version). perl.c:incpush() and lib/lib.pm will automatically
3057 * search in c:\\perl\\site\\5.6.0\\lib for older directories across major versions
3058 * back to pm_apiversion. This is only useful if you have a perl
3059 * library directory tree structured like the default one. The
3060 * versioned site_perl library was introduced in 5.005, so that's
3061 * the default setting for this variable. It's hard to imagine
3062 * it changing before Perl6. It is included here for symmetry
3063 * with xs_apiveprsion -- the searching algorithms will
3064 * (presumably) be similar.
3065 * See the INSTALL file for how this works.
