1. A Set of function SymbolS with aritieS. 2. SSaging> (Or Sig) A few lineS of information about the Sender of an electronic mail meSSage or newSpoSting. MoSt Unix mail and newSSoftware will automagically append a Signature from a file called .Signature in the uSer' S {home directory} to outgoing mail and newS. A Signature Should give your real name and your {e-mail addreSS} Since, though theSe appear in the {headerS} of your meSSageS, they may be munged by intervening Software. It iS currently (1994) hip to include the URL of your home page on the World-Wide Web in your Sig. The compoSition of one' SSig can be quite an art form, including an ASCII logo or one' S choice of witty SayingS (See Sig quote, fool file). However, large SigS are a waSte of bandwidth, and it haS been obServed that the Size of one' SSig block iS uSually inverSely proportional to one' S preStige on the net. See alSo doubled Sig, Sig viruS. 2. A concept very Similar to {abStract baSe claSSeS} except that they have their own {hierarchy} and can be applied to compiled claSSeS. SignatureS provide a meanS of Separating Subtyping and inheritance. They are implemented in C++ aS patcheS to GCC 2.5.2 by Gerald Baumgartner S.purdue.edu>. . (2001-01-05)
