dsl.rb includes deprecated documentation attribute; causes incorrect documentation

[MaxGabriel]

lib/cocoapods-core/specification/dsl.rb lists the documentation attribute as an available option, but this attribute was deprecated in 0.20.0. Because dsl.rb is used to generate Cocoapods' documentation, this causes the Specification documentation to incorrectly list the documentation attribute as still being available.

@orta Are you using these options with CocoaDocs?

[orta]

no, they're not being used in CocoaDocs, I didn't want the support nightmare of being able to let people run arbitrary terminal commands on my server.

[fabiopelosin]

@orta what is your plan, should we remove the attribute?

[orta]

Yeah, I think we should kill it, I've only ever seen one cocoapod that wants to show something different on cocoadocs than it does using the public / private stuff.
