% TODO:
%  Try catch blocks
%  Make an argument type for the \d page argument.
%  deal with xmin, xmax, etc (was there actually a problem we were trying to fix?)
%
%  Redo sseqerrortest and set up regression test script as part of build (damn I didn't realize we'd lost anything imporant with that find -d disaster)
%  Maybe we should add some other regression tests too
%
%  Lower priority:
%   error messages that should be warnings by default?
