The documentation for using <recipe> is rather incomplete -- 
http://0install.net/injector-packagers.html refers to the feed for PySol 
for showing how to use "0store manifest" to fix the checksum of the 
combined package, but unfortunately PySol no longer uses recipes!

I'll probably follow your advice and put the customization script 
elsewhere -- looks like the simpler approach for now, and would also 
allow updates to the customization to be pushed separately.

Thanks,
