Instance Method Details

#generate_rdoc ⇒ Object

Generate the RDoc documents for this gem spec.

Note that if both RI and RDoc documents are generated from the same process, the RI docs should be done first (a likely bug in RDoc will cause RI docs generation to fail if run after RDoc).

#generate_ri ⇒ Object

Generate the RI documents for this gem spec.

Note that if both RI and RDoc documents are generated from the same process, the RI docs should be done first (a likely bug in RDoc will cause RI docs generation to fail if run after RDoc).
