dnl config.m4 for extension %EXTNAME%

dnl Comments in this file start with the string 'dnl'.
dnl Remove where necessary.

dnl If your extension references something external, use with:

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

dnl Otherwise use enable:

PHP_ARG_ENABLE(%EXTNAME%, whether to enable %EXTNAME% support,
dnl Make sure that the comment is aligned:
[  --enable-%EXTNAME%          Enable %EXTNAME% support], no)
