+    longDescription = ''
+      This is a garbage collecting storage allocator that is intended
+      to be used as a plug-in replacement for C's malloc.
+
+      Since the collector does not require pointers to be tagged, it
+      does not attempt to ensure that all inaccessible storage is
+      reclaimed. However, in our experience, it is typically more
+      successful at reclaiming unused memory than most C programs
+      using explicit deallocation. Unlike manually introduced leaks,
+      the amount of unreclaimed memory typically stays bounded.
