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(sm3, for sm3 support,
dnl Make sure that the comment is aligned:
dnl [  --with-sm3             Include sm3 support])

dnl Otherwise use enable:

PHP_ARG_ENABLE(sm3, whether to enable sm3 support,
dnl Make sure that the comment is aligned:
[  --enable-sm3          Enable sm3 support], no)
