# 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.
