Questions about canna-lib and canna-server

["Johnny C. Lam" <jlam@netbsd.org>]

Hi,

	I am rewriting the pkgsrc structure for canna-lib and canna-server
to bring them up-to-date with current pkgsrc standards.  I am not familiar
with the Canna software, so please excuse me if my questions seem silly.
The dictionary structure confuses me:

	/var/dict/canna/*.cbp			Canna-lib dictionary files?
	/var/dict/canna/canna/*.cld		\
	/var/dict/canna/canna/*.cbd		|-- Canna-server dict files?
	/var/dict/canna/canna/*.ctd		/
	/usr/X11R6/share/canna/sample/src/*.ctd	???

(1) Why are the Canna dictionaries stored in /var/dict instead of in
    /usr/pkg/share/canna/dict?

(2) Is it expected that the user may generate and install new dictionary
    files in /var/dict/canna?

(3) Can/do the installed dictionary files change after they are installed,
    so that pkg_delete may not be able to remove them cleanly?

(4) Why are the dictionary files for Canna-lib and Canna-server stored in
    different places (/var/dict/canna and /var/dict/canna/canna)?  It seems
    like the two packages don't share dictionary files with the same
    filename extension (*.cbp and *.{cld,cbd,ctd}), so they should be able
    to share a common dictionary directory.

Thank you for your time.

	Cheers,
