Wasn’t able to find an answer to this one trivially… So gemspecs have the ‘rdoc\_extra\_files’ option to be able to specify README as their main file [index.html]. How might this be accomplished on the command line? rdoc --help doesn’t mention extra files. rdoc --main README results in Generating HTML… Could not find main page README Thanks! -R ---
