I’ve added the following to my .gemrc file:

gem: --rdoc  
rdoc: --fmt ajax --charset utf8 --exclude ._generator._ –  
exclude ._test._ --exclude ._spec._

This automatically builds rdocs on gem install, and gives me the ajax-  
searchable RailsBrain formatter. That part works great. What I’m  
wondering is how can I get it to also do the rdocs on update? For gem  
update I have to generate them manually with:

gem rdoc UPDATED\_GEM\_NAME

Thanks,  
Andrew V.
