 == Building custom versions of Proj4js ==
+
+The proj4js/build directory contains some scripts that can be use to build a single file (buildUncompressed.py) and compressed (build.py) versions of the Proj4js library.  The build process is controlled by the file library.cfg.  To build the library:
+{{{
+cd proj4js/build
+./build.py
+}}}
+
+By default, all projection class code is included in the resulting file.  If only a subset of projections are required, then the library.cfg file can be edited to include or exclude the pieces required.  For example, if your application will only ever use EPSG:27563 and the LCC projection, library.cfg can be edited to be:
+{{{
+[first]
+proj4js.js
+
+[last]
+
+[include]
+projCode/lcc.js
+defs/EPSG27563.js
+
+[exclude]
+defs/*
+}}}
+
+Similarly, OLprototype.cfg is the build configuration file used to create the OLprototype.js file with the OpenLayers build script.  In general, there will be no need to modify this file.
