# Try to find a version of each named file for this machine, and link it into #
# the current working directory.  We use the environment variables  $HOSTNAME #
# and  $SYSTYPE,  and  call  hostype  and .hostype to set them if they aren't #
# already defined.  Suppose we have                                           #
#   $HOSTNAME = foo                                                           #

# and the command is                                                          #
