NAME

       terd - Tool for Entity-Relationship Diagrams

SYNOPSIS

       terd [options] [diagram]

DESCRIPTION

       terd  is  an  X11/Motif based graphical editor for drawing entity-relationship 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.

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

ARGUMENTS

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

       Without  a  diagram  argument,  terd  creates  a  new  empty  entity-relationship  diagram  with the name
       'untitled.erd'.

       In addition to the standard X11 toolkit options (see X11(7)) terd 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 terd.

       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/terd
              the entity-relationship 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.
