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