Class Method Details



  

    .attach(specs, overrides)  
  



  

    
Attach the given overrides onto every LazySpecification in specs so
downstream consumers (LazySpecification#choose_compatible, the install-
time compatibility check, etc.) can read the override list off the spec
itself. Non-LazySpec entries (StubSpecification, ::Gem::Specification, ...)
are left untouched.
