  35 # This script emulates bsd install and also recognises
  36 # two environment variables, with the following semantics :-
  37 #
  38 # $DIST_MANIFEST - if set, the name of the file to append manifest
  39 #                  information in the following format:
  40 #                  File     :  f mode owner group src target
  41 #                  Directory:  d mode owner group target
  42 #                  Symlink  :  l linkval target
  43 #
  44 # $DIST_ROOT     - if set, prepend to target
  45 #
  46 # The sematics of all combinations of these two variables
  47 # are as follows:
  48 #
  49 # $DIST_MANIFEST?  $DIST_ROOT? |   Copy?  Append Manifest?
  50 # -----------------------------+--------------------------
  51 #       not set       not set  |    yes        no
  52 #       not set       set      |    yes        no
  53 #       set           not set  |    no         yes
