#
## Is file really this much of a processing bottleneck? Doubtful.
##
## NOTE: Benchmarked flat files vs. .mgc June 2009, found no measurable
## difference on 3000+ files.
##
## If you really need these (let's say you're doing virus scanning
## and this *would* speed things up quite a bit) you can create
## the pre-parsed file yourself using file's -C option.

## while the magic.mgc file is 1.7M. Considering a difference of 500k,
## and the potential speedup, I'm not sure it's worth the effort...
## but it does make it easier for an admin to add a small chunk of
## new magic.
# IMHO, moving this sort of thing does not make sense.
# We'll support both the traditional and new locations.
