Comment (by RyanGlScott):

 Wow, that script sounds very useful!

 Replying to [comment:6 seraphime]:
 > However, I couldn't find any indications about the release dates of
 versions before 2.01. Should the annotation specify something like "<=
 2.01" or there is some way to find out their respective release dates ?

 I'm not sure, but to be perfectly honest, I don't think anyone actually
 uses `base <= 2.01`, so I'd be OK with simply not giving `@since`
 annotations to things that are that old.

 ?

 The `base-orphans` link is merely a suggestion. If your script works well
 for you, by all means feel free to use that exclusively. But if you do
 need another cross-reference, `base-orphans` is regularly tested against
 multiple GHC versions, so it should be pretty accurate.
