src (src.U):
This variable holds the path to the package source. It is up to

script to make sure (hopefully) that it runs with perl and not some
shell. Of course, that leading line must be followed by the classical
perl idiom:
- eval 'exec perl -S $0 ${1+"$@"}'
- if $running_under_some_shell;
+ eval 'exec perl -S $0 ${1+"$@"}'
+ if $running_under_some_shell;
to guarantee perl startup should the shell execute the script. Note
that this magic incatation is not understood by csh.

+
+xs_apiversion (xs_apiversion.U):
+ 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.
