Stratagus and Wargus are mulltiplatform and there are small platform defined code. Common code is for Debian and Maemo too. I have this idea: * in postinst will be user asked if he want to extract data * When Wargus will be started and data will not found, start postinst script (ask for extracting and extract) It is OK? Adding extract code to Stratagus/Wargus launcher only for Maemo is not good for multiplatform code. This my idea is common for all Debian system.
