***************************************************
**** Code Generation for XCL Constructed Types ****
***************************************************
The following functions generate code for translating between Common Lisp
and XDR. For each function,
    CONTEXT is an RPC-PROGRAM structure with respect to which a
            typedef is being constructed.
    TYPEDEF is an XDR type definition, and
    OPER is either READ (decode) or WRITE (encode).
For all functions except XDR-CODEGEN, a third argument ARGS is a list of
arguments to the code being generated. It always begins with an XDR-stream argument
and for OPER=WRITE is usually followed by the object to be written.

WARNINGS:

(1) DO NOT, REPEAT DO NOT pass an (XDR-CODEGEN-xxx) as the argument of an
(XDR-CODEGEN-xxx). If you do, you might cause the  code generated for
the argument to be evaluated multiple times in the code for the resulting 
expression.

(2) The XDR-CODEGEN-xxx functions code in-line rather than wrap themselves
in LET's or LAMBDA's or whatever. To avoid complications with functions
that require a location-specifier (CHECK-TYPE or CCASE, for example), an
XDR-CODEGEN-xxx function may ***not*** generate code that assumes that its
arguments ARGS or various COUNTs are legitimate location-specifiers. If a 
CHECK-TYPE or similar function is to be done, a LET (or other binding
mechanism) should be generated to create a legal location-specifier." NIL)
