Detailed Description

template<typename A_>
class paludis::SupportsActionTest< A_ >

Instantiated with an Action subclass as its template parameter, SupportsActionTest<> is used by PackageID::supports_action and Repository::some_ids_might_support_action to query whether a particular action is supported by that PackageID or potentially supported by some IDs in that Repository.

Use of a separate class, rather than a mere Action, avoids the need to create bogus options for the more complicated Action subclasses.
