odk/README

 Office development kit - implements the first step on the way to the LibreOffice SDK tarball.
 
 Part of the SDK; to build you need to add --enable-odk.
+
+
+Testing the examples:
+=====================
+
+* See <http://api.libreoffice.org/docs/install.html> how to set up the SDK.
+
+** When asked about it during configuration, tell the SDK to do automatic
+   deployment of the example extensions that get built.
+
+* In a shell set up for SDK development, build (calling "make") and test
+  (following the instructions given at the end of each "make" invocation) each
+  of the SDK's examples/ sub-directories.
+
+** An example script to build (though not test) the various examples in batch
+   mode is
+
+     find examples \( -type d -name nativelib -prune \) -o \
+      \( -name Makefile -a -print -a \( -execdir make \; -o -quit \) \)
+
+   (Note that one of the example extensions asks you to accept an example
+   license on stdin during deployment.)
