dnl ## Process this file with autoconf to produce a configure script.

divert(1)

dnl ## Diversion 1 is the autoconf + automake setup phase. We also
dnl ## set the PHP version, deal with platform-specific compile
dnl ## options and check for the basic compile tools.

dnl ## Diversion 2 is the initial checking of OS features, programs,
dnl ## libraries and so on.

dnl ## In diversion 3 we check for compile-time options to the PHP
dnl ## core and how to deal with different system dependencies.  This
dnl ## includes what regex library is used and whether debugging or short
dnl ## tags are enabled, and the default behaviour of php.ini options.
dnl ## This is also where an SAPI interface is selected (choosing between
dnl ## Apache module, CGI etc.)

dnl ## In diversion 4 we check user-configurable general settings.

dnl ## In diversion 5 we check which extensions should be compiled.
dnl ## All of these are normally in the extension directories.
dnl ## Diversion 5 is the last one.  Here we generate files and clean up.
