I have just made new packages installation. I have installed dictionaries at /var/mobile/Documets and then the app read the dictionary fromm that path.

The most dificult thing was add Depends: line on control file. So, control file was:

...
Depends: MyApp
...

So when a dictionary is selected to install, this line prevents the application is previously installed.

I think it works in the same way Replace: command does.

Waz.
