Tree structure

[rlin@apple.fcit.monash.edu.au (Richard Lin Kuang-Hsu)]

Dear Sir,

	Our Centaur has been runnung OK so far. But there are some
message wont show when we done something wrong. Therefore, I 
have to ask for help.

	Question 1: Can I change the tree structure of my own language(Z),
or I have to follow the tree structure like Exp? I try to update the
directory structure with less levels. I do change all the .rdb files 
correspond to the new directory structure. Then I cannot read the 
test files(e.g, test.Z).
When I change it back, Centaur started to read the files: 
Z : tables read.
Z_code.ll: loaded
Z_sch: loaded

The following is the rdb files:
------ .centaur.rdb ----

Centaur.UserFormalisms: (Z)
Centaur.Z.Database.UserDefaults: \
centaur/Z/Z.rdb
----- Z.rdb ------------

Centaur.Z.Root:      user
Centaur.Z.Location:  centaur/Z/metal

Question 2:
	Is Metal capabile of handling 'user defined data type (e.g., struct
in C)' and 'user defined operator and relationship'?
