  class Memkind(AutotoolsPackage):
      """The memkind library is a user extensible heap manager built on top of
      jemalloc which enables control of memory characteristics and a partitioning
      of the heap between kinds of memory. The kinds of memory are defined by
      operating system memory policies that have been applied to virtual address
      ranges. Memory characteristics supported by memkind without user extension
      include control of NUMA and page size features. The jemalloc non-standard
      interface has been extended to enable specialized arenas to make requests
      for virtual memory from the operating system through the memkind partition
      interface. Through the other memkind interfaces the user can control and
      extend memory partition features and allocate memory while selecting
      enabled features."""
