Also, for such input method plugins, we have a hook and configuration script
"im-config" to initialize such input method environment while starting X.

To update im-config for multiarch, I would like to have access to following
commands without depending on the dpkg-dev package since user program depending
on -dev package is weired:

* current-library-path
  equivalent of
  $ dpkg-architecture|sed -n 's/^DEB_HOST_MULTIARCH=\(.*\)/\1/p'

* installed-library-path
  list all library-path
  I do not know how to get this reliably

I hope someone package this along with extend-library-path

If such dependency pulls in differenrt set of input method for different
architecture, I wonder what will happen and how to deal with such case.
(For now, they all use the same input method and set environment
variable for that one)

(I guess since we are talking spec, there is no tools such as apt-get nor
aptitude to manage such dependencies.)
