I understand that, and those were the DSMs I was referring to as
well.

Why would zippo need a DSM file to know ``how to install a package''?

A simple installation boils down to just unzipping the package over
the old files, and that's it; there's no need for a DSM for this.

Anything smarter than a simple unzip must require a non-trivial DSM
file which cannot possibly come with zippo, unless you, the zippo
maintainers, invest a lot of effort into writing up such non-trivial
DSMs.  (If you do that, those DSMs might as well be simply added to
the *.zip files on SimTel.NET, instead of waiting for maintainers to
do so. ;-)

In other words, I was arguing that the default DSMs must be simple
enough to not convey anything but the ``common-knowledge'' type of
info, which is hardly specific to the packages.  Such a common
knowledge might as well be simply built into zippo to begin with.

Am I missing something?
