gem & rdoc: How to avoid "Could not find main page name" warning when using gems?

[Thomas]

Hi,

When I automatically the rdoc documentation of a gem I made, I always
get this error/warning. I know there is a rdoc command-line option for
defining the main page when invoking rdoc from the command line. But how
do I pass this option from via a gemspec?

Also, Pickaxe 2 mentions a rdoc directive :main: that should set the
main page. But this directive is unknown in the 1.8.2 (cygwin)
distribution. Does the book refer to an upcoming version?

Regards,
Thomas.

Hi. You can see how to specify rdoc options here:
