document some known problems with Mac OS;
2010-04-28, by wenzelm
removed redundant/ignored sort constraint;
2010-04-28, by wenzelm
tuned user-level type abbrevs: explicit warning concerning ignored sort constraints -- sorts never affect formation of types and type abbrevs strip sorts internally;
2010-04-28, by wenzelm
made SML/NJ happy;
2010-04-28, by wenzelm
updated keywords;

command 'defaultsort' is renamed to 'default_sort', it works within a local theory context;

removed material that is out of scope of this manual;
2010-04-28, by wenzelm

removed obsolete sanity check -- Sign.certify_sort is stable;
2010-04-27, by wenzelm
monotonic sort certification: sorts are no longer minimized at the kernel boundary, only when reading input from the end-user;
2010-04-27, by wenzelm
really minimize sorts after certification -- looks like this is intended here;
