[;1m  is_alive()[0m

  Returns [;;4mtrue[0m if the local node is alive (that is, if the node
  can be part of a distributed system), otherwise [;;4mfalse[0m. A node is
  alive if it is started with:

   • [;;4m"erl -name LONGNAME"[0m or,

   • [;;4m"erl -sname SHORTNAME"[0m.

  A node can also be alive if it has got a name from a call to [;;4m[0m
  [;;4mnet_kernel:start/2[0m and has not been stopped by a call to [;;4m[0m
  [;;4mnet_kernel:stop/0[0m.
