Meaning of version tags in cabal files

I noticed that cabal will parse, but ignore, version tags. For example, the two lines appear to be equivalent in how a package gets built: Version: 1.1Version: 1.1-alternate Arguably this is not the right thing to do, as it changes the semantics of versions. For example, I can install version 1.1 of a package without replacing version 1.0, but if I try to install version 1.0-alternate, I will actually replace version 1.0. I'm not against discarding version tags, but I'd like to know if there's a rationale for _silently_ discarding them. -heatsink _________________________________________________________________ Hotmail: Trusted email with Microsoft’s powerful SPAM protection. http://clk.atdmt.com/GBL/go/196390706/direct/01/
