# NAME:
# stage-install.sh - wrapper around install
#
# SYNOPSIS:
# stage-install.sh [variable="value"] "args" "dest"
#
# DESCRIPTION:
# This script is a wrapper around the normal install(1).
# Its role is to add '.dirdep' files to the destination.
# The variables we might use are:
#
# INSTALL
# Path to actual install(1), default is
# $REAL_INSTALL
#
# OBJDIR
# Path to the dir where '.dirdep' was generated,
# default is '.'
#
# _DIRDEP
# Path to actual '.dirdep' file, default is
# $OBJDIR/.dirdep
#
# The "args" and "dest" are passed as is to install(1), and if a
# '.dirdep' file exists it will be linked or copied to each
# "file".dirdep placed in "dest" or "dest".dirdep if it happed
# to be a file rather than a directory.
