Sceda, like sced, is distributed under the GNU copyleft. The source and patches are available.
And there is now a statically linked Linux binary available as well. Sorry, I ain't elfed yet, so this is a.out format. If someone wants to donate an elf binary, I'd be glad to put it up. This is just the binary: for sced and sceda documentation, you'll have to download the entire source tar. And this binary is also on the sceda ftp site below.
This link is for Justyna: entire source tar. :)
Sceda is now also available via anonymous ftp: ftp://ftp.cyberus.ca/pub/sceda
The vanilla sced source is available via anonymous ftp from ftp.cs.su.oz.au:/stephen/sced, and there is also a sced home page.
