FCL2VCG(1) June (2) FCL2VCG(1)
NAME
fcl2vcg - postprocess ftnchek -vcg output to create VCG
input file
SYNOPSIS
ftnchek [ arguments... ] -vcg | fcl2vcg
DESCRIPTION
fcl2vcg is a simple script that filters output from
ftnchek(1) used with the -vcg option, to strip away
everything except the call graph description. The output is
sent to stdout. It can be redirected to a file for later
input to the VCG program. fcl2vcg is only a temporary fix.
A future release of ftnchek will write the VCG description
directly to a file rather than including it in the standard
output.
The VCG input as created is more complex than it need be.
VCG allows graphs and nested subgraphs - each subroutine is
created as a subgraph nested inside its calling routines -
this allows you to interactively display subgraphs or
summarise them. To use the input with VCG an outer
enclosing ``graph{'' and ``}'' may be added, with whatever
global options may be wished.
The -vcg option for ftnchek was written by Dr. Philip Rubini
(p.rubini@cranfield.ac.uk).
VCG is a graph visualisation tool which runs under the X
windows system. It is freely available from
ftp.cs.uni-sb.de. It was written by G. Sander of the
University of Saarland, Germany.
