dnl config.m4 for extension alone

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

dnl Otherwise use enable:

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