3# Script to install Exim binaries in BIN_DIRECTORY, which is defined in
4# the local Makefile. It expects to be run in a build directory. It needs
5# to be run as root in order to make exim setuid to root. If exim runs setuid
6# to (e.g.) exim, this script should be run as that user or root.
7
8# This script also installs a default configuration file in CONFIGURE_FILE
9# if there is no configuration file there, but only if CONFIGURE_FILE specifies
10# single file. If it specifies a list, no action is taken.
11
12# If a default configuration file is installed, the existence of the system
13# aliases file is tested. A default, containing only comments, is installed if
14# necessary.
15
16# If INFO_DIRECTORY is defined in any of the local Makefiles, and the Exim doc
17# directory contains the Texinfo documentation, this script also installs a
18# the info files in INFO_DIRECTORY.
19
20# If DESTDIR is defined, all file paths are prefixed with ${DESTDIR}, with the
21# sole exception of the reference to the system aliases file in the default
22# configuration, because it is assumed that Exim is not actually going to be
23# run from this position. For backward compatibility, if DESTDIR is not
24# defined, ROOT is used instead.
25
26# The script can be made to output what it would do, without actually doing
27# anything, by giving it the option "-n" (cf make). Arguments are the names
28# of things to install. No arguments installs everything.
