@chapter Pathname Evaluation

XXX Include graphic of the path evaluation process with Jennifer's
explanations

@itemize @bullet

@item There are two pathname evaluation routines.  The handler patheval()
is called to find, verify privlages on and return information on a node
that exists.  The handler evalformake() is called to find, verify
permissions, and return information on a node that is to become a parent.  
Additionally, evalformake() returns a pointer to the start of the name of
the new node to be created.
