49# Major Changes:
50
51# - Decimated ProcessRestrictions and broke it into multiple
52# functions joined by a LUT
53# - Semi-Generic SQL stuff moved to another file
54
55# Known Issues: FIXME!
56
57# - ClearRestrictions and Reinitialization is messy and unclear. The
58# only good way to do it is to create a new RT::Tickets object.
