COLLABORATIVE RE-ANALYSIS REQUIREMENTS


In order to provide a rich  environment within which users can function,
it is desired that there be several levels of possible interface to the system
and a comprehensive array of tools provided.

The following should be included:

	a. A command line interface (CLI).
	b. The ability to create and run macros written in the CLI language.
	c. Dynamic linking to user provided  compiled modules written in 
	   C, C++, Fortran and other high level languages.
	d. The ability to run b. and c. interactively or in batch.
	e. Comprehensive set of tools (classes, functions) including math and 
	   visual display (in other words, a development library).
	f. Tools to build GUI  interfaces.
	g. Web interface tools.
	h. Tools for accessing data across a network.
