---+Grammar Engineering Frequently Asked Questions

---++When I switch between grammars (e.g., the English Resource Grammar and a Matrix-derived grammar) the LKB sometimes behaves funny (errors, seg faults, etc.).  What's going on?

Because different grammars tweak the LKB differently through the parameters
files in the =lkb= directory, it is *not* safe to assume that the LKB
is in the same starting state after you load grammar A rather than before
you load grammar B.  In the course of grammar development, we generally don't
have cause to change the parameters files significantly enough to cause a problem
on reloading the same (slightly modified) grammar.  

If you are using another grammar (and particularly one that is not
Matrix derived and/or one that is large enough to have placed specific
requirements on the behavior of the LKB), it is a good idea to restart
the LKB itself when switching between grammars.
