+<p>Deleting a global variable from a module is similar to deleting an
+instruction. First, you must have a pointer to the global variable that you wish
+ to delete. Second, you must have a pointer to the module the global variable
+ belongs to. You use the pointer to the module to get its list of global
+ variables and then use the erase function to remove your global variable.
+ For example:</p>
+
+<div class="doc_code">
+<pre>
+<a href="#GlobalVariable">GlobalVariable</a> *GV = .. ;
+<a href="#Module">Module</a> *M = GV->getParent();
+
+M->getGlobaleList().erase(GV);
+</pre>
+</div>
