TITLE:          C-ACROSS;
VERSION         1.02

DESCRIPTION:   "Utility for multiple module programs. Produces
      Six indexes of functions, prototypes, and globals that
      enable user to 'see across' modules for use in checking
      and comparison.  One of these is type of hierarchical
      functions list, a listing by module of functions
      and calls made FROM them; another is alphabetical list
      of functions and calls made TO them. Globals listed
      in schematic descriptors which record all modifiers
      and qualifiers and enable checking of declarators
      across modules. Creates, on request, header file
      consisting of prototypes constructed from function
      definitions. Can list user types #defined and some
      preprocessor #defines. Full documentation in README.CA";

WARNINGS:      "1. Assumes function definitions conform with
        ANSI standards and have prototype form. See
        also "Caveats and Restrictions" in README.CA.
        2. Assumes syntactically correct source files.
        3. Written and tested using Microsoft QuickC.
