Hmmm, I did exactly this. What I guess is that I have a lot of java packages installed in /usr/share/java and the command lines become too long for the shell script to handle. > > I think about code paths that are only used when you use certain > > features of a program.

When introducing a --prefer= switch thats like hardcoding again. In such cases a helper doesnt really help. It just causes additional work.
