# This script emulates bsd install and also recognises
# two environment variables, with the following semantics :-
#
# $DIST_MANIFEST - if set, the name of the file to append manifest
# information in the following format:
# File : f mode owner group src target
# Directory : d mode owner group target
# Symlink : l linkval target
# $DIST_TMPFILES - if set, the name of the file to append tmpfiles
# information (-t option) in tmpfiles.d format:
# #Type Path Mode User Group Age Argument
# L+ /symlink/to/[re]create - - - - symlink/target/path
#
# $DIST_ROOT - if set, prepend to target
#
# The sematics of all combinations of these two variables
# are as follows:
#
# $DIST_MANIFEST? $DIST_ROOT? | Copy? Append Manifest?
# -----------------------------+--------------------------
# not set not set | yes no
# not set set | yes no
# set not set | no yes
