- Ever heard of NeWS? Which runs on Suns? It's not _Adobe_ PostScript,
- but it is PostScript nonetheless. Especially when looking over the
- client library calls, it looks more like DPS than not. For instance,
- psh, which many NeXT users are familiar with, was apparently one of
- the first NeWS programs available. The server was multi-threaded,
- with separate contexts. It had garbage collection. You could connect
- over the network. It had it's own version of pswrap, cps, which
- converted .cps files into .c files. Sun has a NeWSPrinter (sp?) which
- uses NeWS to rasterize and dumb printing engine to do the actual
- printing. In fact, it even used object-oriented stuff within the
- server, something the NeXT doesn't do. It also tended to put much
- more functionality in the server via postscript routines, whereas NeXT
- puts more emphasis on the client side (these both have advantages and
- disadvantages, of course). And there are probably more NeWS programs
- out there than NeXT programs.
-
- I use past tense above, because NeWS is apparently at an end. Sun
- will still support it, but it is being supplanted by DPS.
-
- [Disclaimer: I found out most of what I know about NeWS _after_ having
- worked on the NeXT for a couple years. So, perhaps I was seeing some
- similarities that weren't really there. But I do think that NeWS was
- written with the DPS documentation in mind :-).]
