NAME

       tdfd - Tool for Data Flow Diagrams

SYNOPSIS

       tdfd [options] [diagram]

DESCRIPTION

       tdfd  is an X11/Motif based graphical editor for drawing data flow diagrams.  Diagrams can
       be loaded from and stored to a file. It can print diagrams to a PostScript printer or save
       as PostScript to a file.

       tdfd is part of The Toolkit for Conceptual Modeling (TCM).

ARGUMENTS

       You can call tdfd with a single diagram name as argument.  If this argument is an existing
       file then tdfd tries to load a diagram from it. If it does not exist,  a  new  diagram  is
       created with the argument as diagram name. tdfd files should have suffix '*.dfd'.

       Without  a  diagram  argument,  tdfd  creates  a new empty data flow diagram with the name
       'untitled.dfd'.

       In addition to the standard X11 toolkit options (see  X11(7))  tdfd  accepts  the  options
       listed below:

       -drawing widthxheight
              Create a drawing area of width pixels wide and height pixels high.

       -help  Write all available options to standard output and quit.

       -maxdrawing widthxheight
              The drawing area can not be larger than width pixels wide and height pixels high.

       -priv_cmap
              Start the editor with a private colormap.

       -projdir directory
              Set the project directory (current working directory) to directory.

       -toEPS [file.eps]
              Generate EPS (to file.eps or stdout when no file name was given) and quit.

       -toFig [file.fig] [-latex]
              Generate  Fig  format  (to file.fig or stdout when no file name was given and quit.
              When the -latex option is  given,  LaTeX  fonts  are  generated,  otherwise  normal
              PostScript  fonts  are  generated.   The  Fig  format  can  be  read by xfig(1) and
              fig2dev(1).

       -toPNG file.png
              Generate PNG format to file.png and quit.

       -toPS [file.ps]
              Generate PostScript (to file.ps or stdout when no file name was given) and quit.

       -version
              Write the TCM version to standard output and quit.

ENVIRONMENT

       The TCM_HOME environment variable  should  be  the  directory  where  the  TCM  files  are
       installed.

       PATH   Should include $TCM_HOME/bin

       MANPATH
              Should include $TCM_HOME/man

       PRINTER
              Name of the default printer that is used by tdfd.

       LD_LIBRARY_PATH
              Should include $TCM_HOME/lib when the distribution contains shared object libraries
              in $TCM_HOME/lib.

FILES

       The following relative files are relative to $TCM_HOME.

       bin/tdfd
              the data flow diagram editor.

       bin/psf
              a program to filter PostScript output.

       lib/banner.ps
              PostScript banner page that can be used when the printer does not  print  a  banner
              page.

       lib/help/*
              The help directory contains a collection of text files for the on-line help.

       lib/TCM
              X  Resources (the same as the ones that are built-in).  You can customize the fonts
              and colors by setting resources in your X defaults database.  Each  string  of  the
              form ``TCM.resource:definition'' sets a resource.

       /tmp/tcmXXXXXX
              Pseudo random temporary file, for PostScript output.

       lib/tcm.conf
              TCM  editor  configuration  file.  This file contains values for some of the editor
              defaults like the page size, the default fonts etc.  This  file  is  read  by  each
              editor upon startup.

       $HOME/.tcmrc
              Each  user  of  TCM  can  override  some  of  the  options  of  tcm.conf by its own
              configuration file, installed in $HOME/.tcmrc.
