3# NAME:
4#	stage-install.sh - wrapper around install
5#
6# SYNOPSIS:
7#	stage-install.sh [variable="value"] "args" "dest"
8#
9# DESCRIPTION:
10#	This script is a wrapper around the normal install(1).
11#	Its role is to add '.dirdep' files to the destination.
12#	The variables we might use are:
13#
14#	INSTALL
15#		Path to actual install(1), default is
16#		$REAL_INSTALL
17#
18#	OBJDIR
19#		Path to the dir where '.dirdep' was generated,
20#		default is '.'
21#
22#	_DIRDEP
23#		Path to actual '.dirdep' file, default is
24#		$OBJDIR/.dirdep
25#
26#	The "args" and "dest" are passed as is to install(1), and if a
27#	'.dirdep' file exists it will be linked or copied to each
28#	"file".dirdep placed in "dest" or "dest".dirdep if it happed
29#	to be a file rather than a directory.
