Yeah, this is nice.  Then things could depend on 'install', it could
have an AfterBuild, etc.  I presume Alias could expand to dirs as
well, and other Aliases.

If Alias takes a command to run (string or coderef or null to do
nothing):

     Alias 'install', qw(/usr/bin/my_prog1 /usr/bin/my_prog2),
           qq(echo '%> up to date.');

then it becomes a pretty general non-file target.  And, even cooler,
it would subsume AfterBuild.  I'd expect the command to only run if
one of the dependencies were updated.

[OK, cons is fun but now I have to get some real work done... how do I
get myself into these discussions???]
