<h4 class="subsection">6.7.2 System Module Installation</h4>
<p>To install a module so that it is available to all Geomview users do
the following
<dl>
<dt>1.<dd>Create a file called <samp><span class="file">.geomview-</span><var>module</var></samp> where
<samp><var>module</var></samp> is the name of the module. This file should contain
a single line which is an <code>emodule-define</code> command for that module:
<pre class="example"> (emodule-define "New Module" "newmodule")
</pre>
<p>The first argument, <code>"New Module"</code> above, is the string that will
appear in the <em>Modules</em> browser. The second string,
<code>"newmodule"</code> above, is the Bourne shell command for invoking the module.
It may include arguments, and you may assume that the module is on the
$path searched by the shell.
<br><dt>2.<dd>Put a copy of the <samp><span class="file">.geomview-</span><var>module</var></samp> and the module
executable itself in Geomview's <samp><span class="file">modules/<CPU></span></samp> directory,
where <samp><span class="file"><CPU></span></samp> is your system type.
</dl>
<p>After these steps, the new module should appear, in alphabetical
position, in the <em>Modules</em> browser of Geomview's <em>Main</em>
panel next time Geomview is run. The reason this works is that when
Geomview is invoked it processes all the <samp><span class="file">.geomview-*</span></samp> files in its
<samp><span class="file">modules</span></samp> directory. It also remembers the pathname of this
directory and prepends that path to the $path of the shell in which it
invokes such a module.
