NAME
       Config::Extensions - hash lookup of which core extensions
       were built.

SYNOPSIS
           use Config::Extensions '%Extensions';
           if ($Extensions{PerlIO::via}) {
               # This perl has PerlIO::via built
           }

DESCRIPTION
       The Config::Extensions module provides a hash %Extensions
       containing all the core extensions that were enabled for
       this perl. The hash is keyed by extension name, with each
       entry having one of 3 possible values:

       dynamic
           The extension is dynamically linked

       nonxs
           The extension is pure perl, so doesn't need linking to
           the perl executable

       static
           The extension is statically linked to the perl binary

       As all values evaluate to true, a simple "if" test is good
       enough to determine whether an extension is present.

       All the data uses to generate the %Extensions hash is
       already present in the "Config" module, but not in such a
       convenient format to quickly reference.
