Hi all!

While doing a system-wide update today, I collected quite some files in 
/var/lib/pkg/rejected. (Great feature, Per!)

Being not only lazy but extremely lazy, I refused to check those files by 
hand. Instead, I hacked together a small script that you might be interested 
in:
It compares the rejected and installed files, presents a diff and applies that 
diff, if so desired. If a file gets updated, it's entry in 
/var/lib/pkg/rejected is removed.

Dependencies: sh, find, diff, vi, dialog, rm
License: GPL
Contributions: more than welcome :-)

Have fun,
Florian

# reconciliate.sh:
# Look at all files in /var/lib/pkg/rejected, show differences to installed
# files, ask whether to update the installed files and do it
# If a file is updated, it is deleted in /var/lib/pkg/rejected. In all other
# cases, the "new" version will stay.

#REQUEST:
# If anybody knows an *easy* way to do a 3-way (or 4-way) selection with
