  25 <strong>gschem</strong> is a <em>schematic  capture</em>  application,  and is part of the <a href="geda-faq.html" class="wikilink1" title="geda-faq.html">gEDA (GPL Electronic Design Automation)</a> toolset.  It is used to draw electronic  <em>schematics</em>,  which  describe the logical structure of an circuit.  Schematics are made up of <em>symbols</em>, which represent the various components in the circuit, and are obtained either from a  standard  library or created by the user.  The connections between components are represented by <em>nets</em> (wires). Schematics may be printed to a PostScript file for printing  or  further  conversion  to other output formats.  Output to various image formats is also supported.
  26 </p>
  27
  28 <p>
  29 gschem can also be used for editing symbols for use in schematics, and for drawing block diagrams of electronics designs.

  45 <li class="level1"><div class="li"> Menu items in the various gschem menus are written using a <strong>bold typeface</strong>, and when a sequence of menu items are to be selected in order, a “→” character is used.
