# This script works with OpenMeta tagging (http://code.google.com/p/openmeta/)
#
# Target folders are tagged with "°target" and a unique tag name
# e.g. "°target reference"
# "°" is option-shift-8
#
# 1 level of subtargets are recognized, using "°subtarget"
# e.g. "°subtarget snippet"
# 
# The folder structure would look like this:
# ~/Documents/Reference			<- tagged "°target reference"
#                 |
#                 - Snippets 	<- tagged "°subtarget snippet"
#
# The file dropped on the Filer would be tagged "reference snippet" to have it placed
# into ~/Documents/Reference/Snippets. If it were tagged with just "reference" it would
# be moved into ~/Documents/Reference, and if it were just tagged "snippet" it would
# throw an error. Subtargets are optional and only function if there's a target match.
# 
# Filer searches the dropped files tags for one that matches an existing °target folder
# It then checks for subtarget matches only within the target folder, therefore, subtargets 
# can be repeated in the system, as long as there's a unique target containing them. If no
# subtarget is found, the main target is assumed to be the destination
#
# Dropped files/folders are moved using UNIX 'mv'. Dropped folders are not recursed.
#
# If the Growl command line utility is installed in '/usr/local/bin/growlnotify', Growl updates
# will be sent. A logfile is created in '~/Library/Application Support/Dropzone/DropzoneFiler.log'
# and shows what files were moved where. Files without tags or without tags that match a target
# are noted as warnings in the log file (and sticky growl messages).
