dnl config.m4 for extension xz

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:

[  --with-xz             Include xz support])

dnl Otherwise use enable:

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