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