 1 Overview
 **********
 
 libIDL is a library licensed under the GNU LGPL for creating trees of
 CORBA Interface Definition Language (IDL) files, which is a
 specification for defining portable interfaces.  libIDL was initially
 written for ORBit (the ORB from the GNOME project, and the primary
 means of libIDL distribution).  However, the functionality was designed
 to be as reusable and portable as possible.
 
    It is written in C, and the aim is to retain the ability to compile
 it on a system with a standard C compiler.  Preprocessed parser files
 are included so you are not forced to rebuild the parser, however an
 effort is made to keep the parser and lexer compatible with standard
 Unix yacc and lex (although bison and flex are more efficient, and are
 used for the preprocessed parsers in the distribution).
 
    With libIDL, you can parse an IDL file which will be automatically
 run through the C preprocessor (on systems with one available), and have
 detailed error and warning messages displayed.  On a compilation
 without errors, the tree is returned to the custom application.  libIDL
 performs compilation phases from lexical analysis to nearly full
 semantic analysis with some optimizations, and will attempt to generate
 meaningful errors and warnings for invalid or deprecated IDL.
 
    libIDL exports functionality used to generate detailed conforming
 error and warning messages in gcc-like format, and also comes with a
 default backend to generate IDL into a file or string (useful for
 customized messages or comments in the output).  The IDL backend is
 complete enough that most generated IDL can be reparsed by libIDL
 without errors. libIDL returns separate syntax and namespace trees, and
 includes functionality to hide syntactical information from the primary
 tree, while keeping it accessible through the namespace for type
 information and name lookup.
 
    Optional extensions to standard IDL can be enabled using parse flags.
 These include node properties, embedded code fragments, and XPIDL.
 Nodes can also have declarations tags which assign particular
 attributions to certain IDL constructs to further facilitate custom
 applications.
