Summary: Addresses the issue of building a generic, flexible,
planning system.  Describes a language (and an associated
interpreter, NASL) which can support not only facts and
rules in the domain (such as operators, etc.) but also
general strategic knowledge about planning such as rules for
ordering subtasks, etc.  Uses predicate calculus as a basis
for the language and uses STP (a theorem prover) for
performing basic operations.  Addresses issues such as
maintenance goals (e.g.  "remain in bounds while getting to
the goal"), resource limited goals (e.g.  "get all the
groceries without spending more than $20"), interleaving
planning with action and the associated problems of recovery
and replanning, etc.  Proposes as open issues topics such as
continuous time and problem reformulation.
