The list of functions available in expressions has
been extended and documented (really!) -
http://sailwave.com/help/HTML/index.html?expression.htm
The idea of the functions like eq (equal to) etc is so that for example
a low/high point system expression can take into account specific
places as exceptions, for example consider something (weird) like
points = place * 2, unless place is less than 3 in which case point =
place. It can be done like this:-
lt(p,3) + gte(p,3)*2
