NAME
APR::Const - Perl Interface for APR Constants

Synopsis
  # make the constants available but don't import them
  use APR::Const -compile => qw(constant names ...);

  # w/o the => syntax sugar
  use APR::Const ("-compile", qw(constant names ...));

  # compile and import the constants
  use APR::Const qw(constant names ...);

  use APR::Socket ();
  use APR::Const    -compile => qw(SO_NONBLOCK);
  ...
  if ($socket->opt_get(APR::Const::SO_NONBLOCK)) {
