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