There is more support for this in 2.1, but not full support.
This would be much more of a win if so much stuff like man and info
pages was not runtime-converted. This is not to say that I think
runtime-conversion is a bad idea. It is rather difficult to support
"file:" access unless you use relative links _everywhere_, with relative
links through a symlink to go from /var/debian-www to /usr/doc and back.
That was rejected as being difficult to explain and not necessary because
of the relative unimportance of the goal of providing "file:" access

I don't see why, given that the user has control over this. I think
95% of servers running under Debian will only serve documentation.
Many users will put a Debian system on their net and then may use
Netscape from some other platform to read its documentation (I do that
a lot from my SGI now).

There is. Remove cgi-bin/debian. Under some servers cgi-bin/debian is
a script, not a symlink (this is the case under WN and could be so for
most other servers) and you can add security features to it if you wish.

Yes, this avoids having two places for documentation. I will state
that packages should install their HTML pages under
/usr/doc/<package-name>/ and the only thing they should install in
/usr/lib/debian-www/ is CGI scripts, which go in

Lars has done a good job at this with "dwww" so far. I am deliberately
leaving this out of the standard until he comes to us with needs that
can't be filled without the cooperation of the installing package.

I can make /usr/doc be exported as http://localhost/debian/doc .
However, the cgi-bin is another story, as there are explicitly ROM and
variable areas for CGI scripts.

The problem is that update-debian-www is intended to appease WWW servers
like WN that need to write an index file of their own in every directory
I think only things that install HTML pages should call update-debian-www.
"dwww" can call the script when it runs to add other kinds of files,
although this will fail (hopefully silently) if /usr/doc really is
read-only when "dwww" runs. update-debian-www must be called before
/usr/doc is made read-only, for example while a plug-and-play CD image is
I can add to the spec that the update-debian-www script
take a list of directory names to be scanned, so
that we can limit its execution time.

OK, that sounds like a good way to handle it, IF you can make run-parts
pass arguments to the scripts it runs. I don't understand why
it should have "CGI" in its name - its major role is to appease WWW
servers like WN that want to put index files in directories that they

OK, given that we will use run-parts.

Currently, all they should do is install HTML pages in their
/usr/doc/<package> directory. Would you like to specify that they
install /usr/doc/<package>/index.html if they install web pages?
