dnl config.m4 for extension event

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(event, for libevent support,
    Make sure that the comment is aligned:
    [  --with-event             Include libevent support])

dnl Otherwise use enable:

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