dnl Comments in this file start with the string 'dnl'.
dnl Remove where necessary. This file will not work
dnl without editing.

dnl If your extension references something external, use with:

PHP_ARG_WITH(gnupg, for gnupg support,
dnl Make sure that the comment is aligned:
[  --with-gnupg             Include gnupg support])

dnl Otherwise use enable:

dnl PHP_ARG_ENABLE(gnupg, whether to enable gnupg support,
dnl Make sure that the comment is aligned:
dnl [  --enable-gnupg           Enable gnupg support])
