The hash is keyed by extension name, with each entry having one of 3 possible values: =over 4 =item dynamic The extension is dynamically linked =item nonxs The extension is pure perl, so doesn't need linking to the perl executable =item static The extension is statically linked to the perl binary =back As all values evaluate to true, a simple C<if> test is good enough to determine whether an extension is present. All the data uses to generate the C<%Extensions> hash is already present in the C<Config> module, but not in such a convenient format to quickly reference. =head1 AUTHOR Nicholas Clark <nick@ccl4.org> =cut
