Here are the supporting scripts for building the win32 PHP installer.
Requirements:
MSI-2-XML from http://msi2xml.sourceforge.net/#Installation
Installer Layout:
We have the following features:
o PHP Core - Always installed.
Includes php4ts.dll, php.ini + common dlls
and config files
o SAPI
Contains a node for each stable SAPI
o Extensions
Contains a node for each stable extension
o Experimental
o SAPI Experimental SAPIs
o Extensions Experimental Extensions
You need to have the Super-Pimp Installer from Nullsoft (Open Source).
It is available here:
http://nsis.sourceforge.net/

To build an installer, you need:
o A Source Tree
o A win32 snapshot (extracted from the .zip)
o A Source Tree

(The source tree and snapshot should have matching versions!)
