+MySQL Extension for PHP 4.0 - Win32 README
+------------------------------------------
+
+In order to compile this extension, MySQL must be installed in a parrallel directory
+to that of PHP 4.0.  For example, if you have PHP 4.0's source tree set up in
+C:\Projects\php4, you must have MySQL set up in C:\Projects\MySQL.  The compiler
+will look for include files in C:\Projects\MySQL\include and for the library
+files in C:\Projects\MySQL\lib.
+
+You can change this by editing the project settings, but it's not recommended, since
+you will have to do it every time you obtain a new version of the PHP 4.0 source tree.
