<para>Set an environment variable to a new value, similar to the shell's
export or setenv command. The
<replaceable>variable</replaceable>
and its
<replaceable>value</replaceable>
are inherited by processes started directly by fvwm. This can be
especially useful in conjunction with the
<fvwmref mod="FvwmM4"/>
module. For example:</para>
<programlisting>
SetEnv height HEIGHT
</programlisting>
<para>makes the <fvwmref mod="FvwmM4"/> set variable
<emphasis remap='I'>HEIGHT</emphasis>
usable by processes started by fvwm as the environment variable
<emphasis remap='I'>$height</emphasis>.
If
<replaceable>value</replaceable>
includes whitespace, you should enclose it in quotes. If no
<replaceable>value</replaceable>
is given, the variable is deleted.</para>
