Cause if API doesn't brake there is no problem when you have 1.4 installed why you shouldn't use a program that was "originally designed to run with 1.3" - since this would lead to unnecessary trouble (e.g. if an important bugfix might come out and the version number changes). > You also agreed to my FileroleHandler-Class.

That's a nice idea ... ask the user. Hmm - why haven't we thought of this before? Maybe we could Also add special strings which have a value (as standard setting) but still are asked for by the user (displaying the standard, if he just presses enter). > pear-app would now try to install the package taking care of the > new dir settings.
