+Installation:
+
+ You'll want to have the following sources available somewhere:
+ php
+ rrdtool
+ apache (if you built php as a DSO)
+
+ Edit the *INCLUDE and *LIB variables in the Makefile to indicate
+the correct locations for your files.
+
+ After php3_rrdtool.so builds correctly, copy this file to wherever
+you'd like. Possibly APACHE_ROOT/libexec/ .
+
+
+
+After you install, you should probably read README and API.
