+======Synopsis:======
+__unless__ (<condition>) <then>
+__unless__ (<condition>) { <then> } [{ <else> }] \\
+__unless__ (<condition>) { <then> } elsif (<condition>) { <then> } else { <then> } \\
+__unless__ (<condition>) { <then> } elif (<condition>) { <then> } \\
+__unless__ (<condition>) { <then> } else if (<condition>) { <then> } \\
+======Description:======
+__UNLESS__ is the inverse of the [[IF]] command.  If <condition> is
+FALSE then <then> is is executed.  If <condition> is TRUE then any further
+else oe elseif conditions are parsed until a <condition> is found that is
+FALSE.  Note that even though the word "elsif" and "elif" are used, that
+does not change that it is looking for a <condition> that is FALSE.
+For all the other gory details, see the [[IF]] help file.
+======Examples:======
+   unless (1 == 1) {
+      echo 1 == 1.  This is not executed, because 1 == 1 is TRUE
+   } elsif (1 == 0) {
+      echo 1 == 0.  This is executed because 1 == 0 is FALSE.
+   } else {
+      echo ha!  This is not executed because 1 == 0 is FALSE.
+   }
+======History:======
+The __UNLESS__ command first appeared in EPIC3.
