   6 # This script emulates bsd install and also recognises
   7 # two environment variables, with the following semantics :-
   8 #
   9 # $DIST_MANIFEST - if set, the name of the file to append manifest
  10 #                  information in the following format:
  11 #                  File     :  f mode owner group src target
  12 #                  Directory:  d mode owner group target
  13 #                  Symlink  :  l linkval target
  14 #
  15 # $DIST_ROOT     - if set, prepend to target
  16 #
  17 # The sematics of all combinations of these two variables
  18 # are as follows:
  19 #
  20 # $DIST_MANIFEST?  $DIST_ROOT? |   Copy?  Append Manifest?
  21 # -----------------------------+--------------------------
