*** CONFIGURATION

VDT(VHDL Developer's Toolkit) is a software package which is developed
using the C++ programming language. This package includes a library of
versatile routines and several basic tools which enable easy and quick
development of VHDL application tools. The core module of this toolkit
is PI(Procedural Interface) which is a library through which application
tools can efficiently manipulate VHDL intermediate forms. As basic tools
provided by the toolkit, there are a VHDL analyzer, a VHDL generator, a
library browser, and so on. The toolkit is based on a data model which has
been designed to represent the basic structure of the VHDL intermediate
form. The data model supports the full set of IEEE Std 1076-1987.

All tools using VDT initially read the configuration file. For quick use
of VDT basic tools, setup user's configuration file which may be located
in home-directory and/or current directory. Creation of new design library
is accomplished just by assigning the logical name of design library to a
directory path-name of UNIX file system. The following is the synopsis of
new design library creation.

	LIBRARY	str1 str2
	char* str1; -- logical design library name.
	char* str2; -- path-name of a directory.

Default libraries are configured in a special file named "$VDT/etc/.VDTRC".
This file configures basically the design libraries named "STD" and "WORK",
and includes other configuration files named "~/.vdtrc" and "./.vdtrc". If
there are one more configuration for a same design library with different
path-name, the last configuration overrides.
