+?S: This variable holds a list of all extensions (both XS and non-xs)
+?S: included in the package source distribution. This information is
+?S: only really of use during the Perl build, as the list makes no
+?S: distinction between extensions which were build and installed, and
+?S: those which where not. See "extensions" for the list of extensions
+?S: actually built and available.
?S:.
?S:dynamic_ext:
?S: This variable holds a list of XS extension files we want to
?S: link statically into the package. It is used by Makefile.
?S:.
?S:nonxs_ext:
-?S: This variable holds a list of all non-xs extensions included
-?S: in the package. All of them will be built.
+?S: This variable holds a list of all non-xs extensions built and
+?S: installed by the package. By default, all non-xs extensions
+?S: distributed will be built, with the exception of platform-specific
+?S: extensions (currently only one VMS specific extension).
?S:.
?S:extensions:
?S: This variable holds a list of all extension files (both XS and
-?S: non-xs linked into the package. It is propagated to Config.pm
-?S: and is typically used to test whether a particular extesion
+?S: non-xs) installed with the package. It is propagated to Config.pm
+?S: and is typically used to test whether a particular extension
?S: is available.

?S: command line.
