+    longDescription = ''
+      The Boehm-Demers-Weiser conservative garbage collector can be used as a
+      garbage collecting replacement for C malloc or C++ new.  It allows you
+      to allocate memory basically as you normally would, without explicitly
+      deallocating memory that is no longer useful.  The collector
+      automatically recycles memory when it determines that it can no longer
+      be otherwise accessed.
+
+      The collector is also used by a number of programming language
+      implementations that either use C as intermediate code, want to
+      facilitate easier interoperation with C libraries, or just prefer the
+      simple collector interface.
+
+      Alternatively, the garbage collector may be used as a leak detector for
+      C or C++ programs, though that is not its primary goal.
