+/**
+ * Convenience function for generating a form from a view in a standard location.
+ *
+ * This function assumes that the body of the form is located at "forms/$action" and
+ * sets the action by default to "action/$action".  Automatically wraps the forms/$action
+ * view with a <form> tag and inserts the anti-csrf security tokens.
+ *
+ * @example
+ * <code>echo elgg_view_form('login');</code>
+ *
+ * This would assume a "login" form body to be at "forms/login" and would set the action
+ * of the form to "http://yoursite.com/action/login".
+ *
+ * If elgg_view('forms/login') is:
+ * <input type="text" name="username" />
+ * <input type="password" name="password" />
+ *
+ * Then elgg_view_form('login') generates:
+ * <form action="http://yoursite.com/action/login" method="POST">
+ *     ...security tokens...
+ *     <input type="text" name="username" />
+ *     <input type="password" name="password" />
+ * </form>
+ *
+ * @param string $action    The name of the action (without the leading "action/") -- e.g. "login"
+ * @param array  $form_vars $vars environment passed to the "input/form" view
+ * @param array  $body_vars $vars environment passed to the "forms/$action" view
+ *
+ * @return string The complete form
