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.
