I suspect that zeroinstall is the native, cross-platform package
installer that Rox uses, and quite possibly that a lot of the
file-type handlers for the rox file manager are available as
zero-install packages. Stll, I'd like to *know* that instead of just
suspecting it.
Zeroinstall can apparently allow users to install packages without
requiring them to have administrative privileges, can ensure that
when the same version of the same package is installed by different
users, only one copy occupies disk space, keep track of which
users belong with which packages (so they don't get their stuff mixed
up) and install multiple different versions of one package in case
users have different constraints because of the curse of
compatibility.
Annd, to my surprise, the current zeroinstall is written in OCaml, a
language that's a pretty good tool for writing reliable software. The
previous version was apparently written in python.
Rox as an environment seems little maintained and quite old, the website says it
is "RISC OS for X". They had an application-as-folder system and Rox-filer would
still deal with these if you used them, they called this system zeroinstall
since it just required copying the self-contained application folder. Probably
has the same ultimate ancestry as Apple's application folder system.
