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%],
dnl   [for %EXTNAME% support],
dnl   [AS_HELP_STRING([--with-%EXTNAME%],
dnl     [Include %EXTNAME% support])])

dnl Otherwise use enable:

PHP_ARG_ENABLE([%EXTNAME%],
  [whether to enable %EXTNAME% support],
  [AS_HELP_STRING([--enable-%EXTNAME%],
    [Enable %EXTNAME% support])],
  [no])
