We usually prefer using MANPATH. Directories under man tend
to be large, and its difficult to know what man pages are part
fo what packages... MANPATH deals with it in a simple and flexible
way. And when you want to delete a package, you just rm the directory
under installed... Of course this may be diffeent if you have a tool...
Then you could just use it to delete the man pages... if you have
a file with the info.

Well, the thing is a bit more complicated.... Under /usr/general/arch
you have the 'real dirs' for different OSs. /usr/local/bin in NetBSD is,
for example, a link to /usr/general/arch/netbsd/usr.local/bin.
When you want to get a package and install it, you first go to
/usr/general/distrib (if distirubtion is source) or to
/usr/local/packages/distrib (if its binary for the architecture).
You open a new dir there, and ftp the package. Then, if it is
'ready to run' (eg., binaries, Tcl/Tk scripts and so on), you
open a dir under /usr/local/packages/installed or under
/usr/general/installed, and unpack the thing there (usually, with
bin, doc, lib, man subdirectories). The you config things so that
e.g. config files are found, and make links *only for the binaries*
(and libs, if other packages may need them). Add the new man path
to MANPATH, and everithing is ready. All machines of that architecture
on the net (or *all* the machines, if the thing was general)
see the package, and can work with it.
If the package needs to be compiled, I use to unpack it
under /usr/local/packages/test, configure and compile there, test it
if possible, and install under /usr/local/packages/installed.
Anyway, most of this scheme is 'static', in the sense that
you need only having a couple of links in all the machines
(for example, from /usr/local to /usr/general/arch/OS-type/usr.local),
and /usr/general importe by all the machines. The only `dynamic'
links ---that must be done per package--- are those under
/usr/local/bin... That where your tool can be very useful.

Well, I'll try your tool... Sounds good. (about /opt, yes
I prefer /usr/general, but that may be a religious war.... ;-) )

Maybe this is the time for discussing this... I have some
space in a ftp server, wich I can devote to NetBSD/i386. Maybe
now, with the upcoming 1.0, it's the right moment...
What do you think, netbsd users?
