[Dict-common-dev] Experimental support for regions-to-spelling.map

[Rafael Laboissiere]

Okay, it is raining today in my town and I could not refrain myself from
implementing the automatic generation of the regions-to-spelling.map file of
the libspell4 package.

First of all, I apologize for going on without waiting for the follow-up of
the discussion.  For that reason, I consider my changes quite experimental,
and if it happens that I made bad choices, we can revert the code to the
previous state.

I decided to let the individual IDWP have total control on the contents of
regions-to-spelling.map.  IMO, it is much better so, because it would be a
burden to either the libpspell or the dictionaries-common maintainers to keep
up with changes in locale definitions and pwli file names.  

The dictionaries-common generates now automatically the
regions-to-spelling.map file each time a new dictionary is installed (in the
same way JEd and emacsen support is generated).  This file is now in
/var/cache/dictionaries-common.  In order to make things work without
changes in the libpspell package, the dictionaries-common package does two
things:

    1) Diversion of the /usr/share/pspell/regions-to-spelling.map file.
       (This is why a new debian/dictionaries-common.preinst has been
       added.)

    2) Creation of the symlink /usr/share/pspell/regions-to-spelling.map ->
       /var/cache/dictionaries-common/regions-to-spelling.map    

On the IDWP maitainer side, the only new thing that is required is the
addition of a new field in debian/info-ispell file, like this:

    Locale: pt_BR

I committed the changes to the dict-common CVS repository and uploaded to
the staging area two modified Ispell dict package: ibrazilian and
iportuguese.  I tested the changes with abiword and it seems to work.

Please, test the new scheme.  Comments, as usual, are welcome.  If my
changes are adopted, I would appreciate that a brave soul (Agustín? :-) make
the necessary changes to the Policy document.
