The same type as RCS :). Maybe "revision control systems." As you
mention, it is not so important exactly what they are called as long as
similar ones are grouped together. This certainly tells you more then
"developer utilities." It is supposed to be much more specific then the
category, even more specific then the general application it concerns.
i.e. "irc server" and "irc client" and "irc bot" are all irc
applications, but people who are interested in one are not necessarily
interested in the others. And all of these are currently in the same
catagory as coda and bind4. Currently, you would have to grep COMMENT to
find similar TYPE applications, which might not work if the package
creators used differet wording. It may not be too hard to read each one
when there are 50 packages in a category, but what happens when there are
500? And does a www library go under www or devel?
Actually, it would probably be more useful to all packages to have
several types, so, say, an office suite could have type "word processor",
"spreadsheet", etc. and maybe also "office suite." Similarly, a p5 CGI
module might have types "perl5 module" and "CGI library."

(b) could be worked around by creating a pkgsrc/Types.txt file that
lists all possible types (I ment to say this before but forgot to mention
it). (a) is the whole point of the idea. While general catagories are
very good to have, it would also IMO be good to have a way of locating
applications more specificly.

I agree this is a bad idea. This is why I suggested a pkg file instead
of directory reorganization.

Do the current *.html files appear in the CVS tree? I don't think they
do (they aren't in the main sup anyway...) This is why I suggested that
the bytype directory tree (however it is designed) be autogenerated. This
way, those that want it can crate it while CVS does not have to worry
about it. It may be that there would be too many TYPEs for a directory to
make sense, but at least there would be an easy way to search for
applications of one type.

If I'm looking for an irc client, I want to be able to list all irc
clients in the package system. I don't care about coda or bind or archie
or irc servers or anything else in the net catagory, I just want to see
the irc clients. TYPE is just a more organized way of doing this then
searching COMMENT for text that the package maintainer may or may not have
put in the description.
