dnl Autotools config.m4 for PHP extension %EXTNAME%

dnl Comments in this file start with the string 'dnl' (discard to next line).
dnl Remove where necessary.

dnl If extension references and depends on an external library package, use
dnl the '--with-%EXTNAME%' configure option:
dnl PHP_ARG_WITH([%EXTNAME%],
dnl   [for %EXTNAME% support],
dnl   [AS_HELP_STRING([--with-%EXTNAME%],
dnl     [Include %EXTNAME% support])])

dnl Otherwise use the '--enable-%EXTNAME%' configure option:
PHP_ARG_ENABLE([%EXTNAME%],
  [whether to enable %EXTNAME% support],
  [AS_HELP_STRING([--enable-%EXTNAME%],
    [Enable %EXTNAME% support])],
  [no])
