I like your idea, except that I hope you don't mean to have such
file in wmii's virtual filesystem, but define that stuff in
wmiirc instead and having an event whenever a new window
appears, that you can match your rules with awk from wmiirc and
writing the specific tags to /clients/<id>/tags.

This would allow easy xprops integration. The event
might only provide the window id which can be used as argument
for xprop, ie: xprop -id <id> (that is no big deal and can be
easily supplied as event argument). Instead of using the global
array indexes as directory names in /clients/ we could use
the window id instead, ie /clients/0x600020/...
(actually it is only important to have the indexes in /ws
namespace, but knowing the wmii indexes in /clients is pretty
pointless). Assumed you receive some event (MC = manage client)

MC 0x600020

in wmiirc you could run xprops -id 0x600020, match whatever you
like and do

xwrite /clients/0x600020/tags +new -web

for example. This would remove all this complexity from wmii and
prevent us inventing the wheel of a matching language and allow
the user much flexibility (we only have to take care about

Those should be checked against WM_CLASS, ie

WM_CLASS(STRING) = "xterm", "XTerm"

(output for xterm)

I'd like to get rid of the /def/class handling within the WM, we
could safe a lot of code without it (approx. 200 lines).
