# If using the usebuggroups parameter, users shouldn't be able to see
# reports for products they don't have access to.
# Gervase Markham <gerv@gerv.net> and Adam Spiers <adam@spiers.net>
# Added ability to chart any combination of resolutions/statuses.
# Derive the choice of resolutions/statuses from the -All- data file
# Removed hardcoded order of resolutions/statuses when reading from
# daily stats file, so now works independently of collectstats.pl
# version
# Added image caching by date and datasets
# Myk Melez <myk@mozilla.org):
# Implemented form field validation and reorganized code.
