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. | |
