+# NAME
+#	postfix-install 1
+# SUMMARY
+#	Postfix installation procedure
+# SYNOPSIS
+#	sh postfix-install [options] [name=value] ...
+# DESCRIPTION
+#	The postfix-install script is to be run from the top-level
+#	Postfix source directory. It implements the following operations:
+# .IP o
+#	Install or upgrade Postfix from source code. This requires
+#	super-user privileges.
+# .IP o
+#	Build a package that can be distributed to other systems, in order
+#	to install or upgrade Postfix elsewhere. This requires no super-user
+#	privileges. To complete the installation after unpacking the
+#	package, execute as super-user the post-install script in the Postfix
+#	configuration directory.
+# .PP
+#	The postfix-install script is controlled by installation parameters.
+#	Specific parameters are described at the end of this document.
+#
+#	By default, postfix-install asks the user for installation
+#	parameter settings. Most settings are stored in the installed
+#	main.cf file. Stored settings are used as site-specific defaults
+#	when the postfix-install script is run later.
+#
+#	The names of Postfix files and directories, as well as their
+#	ownerships and permissions, are stored in the postfix-files file
+#	in the Postfix configuration directory. This information is used
+#	by the post-install script (also in the configuration directory)
+#	for creating missing queue directories when Postfix is started,
+#	and for setting correct ownership and permissions when Postfix
+#	is installed from a pre-built package or from source code.
+#
+#	Arguments
+# .IP -keep-build-mtime
+#	When installing files preserve new file's mtime timestamps.
+#	Otherwise, mtimes will be set to the time that postfix-install
+#	is run.
+# .IP -non-interactive
+#	Do not ask the user for parameter settings. Installation parameters
+#	are specified via one of the non-interactive methods described
+#	below.
+# .IP -package
+#	Build a ready-to-install package. This requires that a
+#	non-default install_root parameter is specified.
+# INSTALLATION PARAMETER INPUT METHODS
+# .ad
+# .fi
+#	Parameter settings can be specified through a variety of
+#	mechanisms.  In order of decreasing precedence these are:
+# .IP "interactive mode"
+#	By default, postfix-install will ask the user for installation
+#	parameter settings. These settings have the highest precedence.
+# .IP "command line"
+#	Parameter settings can be given as name=value arguments on
+#	the postfix-install command line. This mode will replace
+#	the string MAIL_VERSION at the end of a configuration
+#	parameter value with the Postfix release version (Postfix
+#	3.0 and later).
+# .IP "process environment"
+#	Parameter settings can be given as name=value environment
+#	variables. Environment parameters can also be specified on
+#	the make(1) command line as "make install name=value ...".
+#	This mode will replace the string MAIL_VERSION at the end
+#	of a configuration parameter value with the Postfix release
+#	version (Postfix 3.0 and later).
+# .IP "installed configuration files"
+#	If a parameter is not specified via the command line or via the
+#	process environment, postfix-install will attempt to extract its
+#	value from an already installed Postfix main.cf configuration file.
+# .IP "built-in defaults"
+#	These settings have the lowest precedence.
+# INSTALLATION PARAMETER DESCRIPTION
+# .ad
+# .fi
+#	The description of installation parameters and their built-in
+#	default settings is as follows:
+# .IP install_root
+#	Prefix that is prepended to the pathnames of installed files.
+#	Specify this ONLY when creating pre-built packages for distribution to
+#	other systems. The built-in default is "/", the local root directory.
+#	This parameter setting is not recorded in the installed main.cf file.
+# .IP tempdir
+#	Directory for scratch files while installing Postfix.
+#	You must have write permission in this directory.
+#	The built-in default directory name is the current directory.
+#	This parameter setting is not recorded in the installed main.cf file.
+# .IP config_directory
+#	The final destination directory for Postfix configuration files.
+#	The built-in default directory name is /etc/postfix.
+#	This parameter setting is not recorded in the installed main.cf file
+#	and can be changed only by recompiling Postfix.
+# .IP data_directory
+#	The final destination directory for Postfix-writable data files such
+#	as caches. This directory should not be shared with non-Postfix
+#	software. The built-in default directory name is /var/lib/postfix.
+#	This parameter setting is recorded in the installed main.cf file.
+# .IP daemon_directory
+#	The final destination directory for Postfix daemon programs. This
+#	directory should not be in the command search path of any users.
+#	The built-in default directory name is /usr/libexec/postfix.
+#	This parameter setting is recorded in the installed main.cf file.
+# .IP command_directory
+#	The final destination directory for Postfix administrative commands.
+#	This directory should be in the command search path of adminstrative
+#	users. The built-in default directory name is system dependent.
+#	This parameter setting is recorded in the installed main.cf file.
+# .IP html_directory
+#	The final destination directory for the Postfix HTML files.
+#	This parameter setting is recorded in the installed main.cf file.
+# .IP queue_directory
+#	The final destination directory for Postfix queues.
+#	The built-in default directory name is /var/spool/postfix.
+#	This parameter setting is recorded in the installed main.cf file.
+# .IP sendmail_path
+#	The final destination pathname for the Postfix sendmail command.
+#	This is the Sendmail-compatible mail posting interface.
+#	The built-in default pathname is system dependent.
+#	This parameter setting is recorded in the installed main.cf file.
+# .IP newaliases_path
+#	The final destination pathname for the Postfix newaliases command.
+#	This is the Sendmail-compatible command to build alias databases
+#	for the Postfix local delivery agent.
+#	The built-in default pathname is system dependent.
+#	This parameter setting is recorded in the installed main.cf file.
+# .IP mailq_path
+#	The final destination pathname for the Postfix mailq command.
+#	This is the Sendmail-compatible command to list the mail queue.
+#	The built-in default pathname is system dependent.
+#	This parameter setting is recorded in the installed main.cf file.
+# .IP mail_owner
+#	The owner of the Postfix queue. Its numerical user ID and group ID
+#	must not be used by any other accounts on the system.
+#	The built-in default account name is postfix.
+#	This parameter setting is recorded in the installed main.cf file.
+# .IP setgid_group
+#	The group for mail submission and for queue management commands.
+#	Its numerical group ID must not be used by any other accounts on the
+#	system, not even by the mail_owner account.
+#	The built-in default group name is postdrop.
+#	This parameter setting is recorded in the installed main.cf file.
+# .IP manpage_directory
+#	The final destination directory for the Postfix on-line manual pages.
+#	This parameter setting is recorded in the installed main.cf file.
+# .IP sample_directory
+#	The final destination directory for the Postfix sample configuration
+#	files. This parameter is obsolete as of Postfix version 2.1.
+#	This parameter setting is recorded in the installed main.cf file.
+# .IP meta_directory
+#	The final destination directory for non-executable files
+#	that are shared among multiple Postfix instances, such
+#	as postfix-files, dynamicmaps.cf, as well as the multi-instance
+#	template files main.cf.proto and master.cf.proto. This
+#	directory should contain only Postfix-related files.
+# .IP readme_directory
+#	The final destination directory for the Postfix README files.
+#	This parameter setting is recorded in the installed main.cf file.
+# .IP shlib_directory
+#	The final destination directory for Postfix shared-library
+#	files, and the default directory for Postfix database plugin
+#	files with a relative pathname in the file dynamicmaps.cf.
+#	This directory should contain only Postfix-related files.
+#	The shlib_directory parameter built-in default value is
+#	specified at compile time.  If you change this at installation
+#	time, then additional configuration will be required with
+#	ldconfig(1) or equivalent.
