ASSET_A_199:  APFAT (Ada Program Flow Analysis Tool)
     APFAT is an object-based, menu-driven program which produces the following
reports: main indented call tree summary, subprogram  invocations, subprogram 
references, exceptions usage summary, exceptions raised-by summary, identifier 
usage summary, user specified identifier usage summary, Booch diagrams, and 
program metrics. These reports may be directed to the user's screen or 
redirected to any output file.
     The program is designed to process syntactically correct Ada source
code in the correct compilation order. It runs on an Apollo system with UNIX 
under BSD4.2 and the Verdix Compiler SRS 3.5.1.
