   1 The following is a demonstration of the mmapfiles.d script.

   3 Here we run mmapfiles.d while in another window a new bash shell is started.
   4 The files that were mapped in aren't suprising, they are the common shared
   5 librarios,

  19 Now we examine zsh. This time a number of extra libraries are mapped,

  45 Sometimes the output can be quite suprising. The following shows the mmaps
