-apiversion (patchlevel.U):
- This is a number which identifies the lowest version of perl
- to have an API (for XS extensions) compatible with the present
- version. For example, for 5.005_01, the apiversion should be
- 5.005, since 5.005_01 should be binary compatible with 5.005.
- This should probably be incremented manually somehow, perhaps
- from patchlevel.h. For now, we'll guess maintenance subversions
- will retain binary compatibility.
+api_revision (patchlevel.U):
+ The three variables, api_revision, api_version, and

+ Prior to 5.5.640, the format was a floating point number,
+ like 5.00563.
+ perl.c:incpush() and lib/lib.pm will automatically search in
+ $sitelib/.. for older directories back to the limit specified
+ by these api_ variables. 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. The version list appropriate for the current
+ system is determined in inc_version_list.U.
+ XXX To do: Since compatibility can depend on compile time
+ options (such as bincompat, longlong, etc.) it should
+ (perhaps) be set by Configure, but currently it isn't.
+ Currently, we read a hard-wired value from patchlevel.h.
+ Perhaps what we ought to do is take the hard-wired value from

+ options warrant. patchlevel.h then would use an #ifdef guard.
