# copied from one of the well known/talented OSX developers who posted this simple snippet somewhere, since the
# uti/filemap situation is quite confusing on 10.6.
# there are other solutions, even in python, that have been done using graphviz to create a huge graph/network
# of the relationships (can get rather large if you have >100apps). And, there are other solutions like
# setting an application's affinity (code is on github by another great developer),
# and a 10.6 service. I would think that these are going to get more complex, even becoming a niche industry for
# someone to make $10 via registration off of at some point, since the new UTI system has some potential (using magic vs file suffix, etc)
