# The below points were mentioned to Vernier in their forum:
# http://www.vernier.com/forums/logger-pro-linux/404-packaging-improvements/
#
# /usr/share/LoggerPro/Experiments/ will remain 0755; only the sysadmin
# should be writing to this. TODO: Contact Vernier about this.
# Thinking to myself here... Would be nice to have a three-tier system maybe,
# e.g. /usr/share/LoggerPro/Experiments/, then check a sysadmin configured
# location (e.g. /data/common/LoggerPro/Experiments/ is something like I 
# would have), then $HOME, e.g. $HOME/LoggerPro/Experiments/, with all
# three (if set) being check and the contents merged, and each level 
# overrides (e.g. same-named files) the previous levels. 
# While I'm writing, for the love of sanity, PLEASE use /tmp or /var/tmp
# or some other place, or at least make it configurable in a systemwide
# config file at e.g. /etc/Vernier/LoggerPro.conf (this would be a good
# place to make the other stuff above configurable too)
# Note the move of udev files to /lib/udev instead of /etc/udev

# Work around the hardcoding of /usr/local (I can't figure out where it's
# hardcoded or thus how to fix it)
