+/* NAME
+/* postmap 1
+/* SUMMARY
+/* Postfix lookup table management
+/* SYNOPSIS
+/* .fi
+/* \fBpostmap\fR [\fB-bfFhimnNoprsuUvw\fR] [\fB-c \fIconfig_dir\fR]
+/* [\fB-d \fIkey\fR] [\fB-q \fIkey\fR]
+/* [\fIfile_type\fR:]\fIfile_name\fR ...
+/* DESCRIPTION
+/* The \fBpostmap\fR(1) command creates or queries one or more Postfix
+/* lookup tables, or updates an existing one.
+/*
+/* If the result files do not exist they will be created with the
+/* same group and other read permissions as their source file.
+/*
+/* While the table update is in progress, signal delivery is
+/* postponed, and an exclusive, advisory, lock is placed on the
+/* entire table, in order to avoid surprises in spectator
+/* processes.
+/* INPUT FILE FORMAT
+/* .ad
+/* .fi
+/* The format of a lookup table input file is as follows:
+/* .IP \(bu
+/* A table entry has the form
+/* .sp
+/* .nf
+/* \fIkey\fR whitespace \fIvalue\fR
+/* .fi
+/* .IP \(bu
+/* Empty lines and whitespace-only lines are ignored, as
+/* are lines whose first non-whitespace character is a `#'.
+/* .IP \(bu
+/* A logical line starts with non-whitespace text. A line that
+/* starts with whitespace continues a logical line.
+/* .PP
+/* The \fIkey\fR and \fIvalue\fR are processed as is, except that
+/* surrounding white space is stripped off. Whitespace in lookup
+/* keys is supported in Postfix 3.2 and later, by surrounding the
+/* key with double quote characters `"'. Within the double quotes,
+/* double quote `"' and backslash `\\' characters can be included
+/* by quoting them with a preceding backslash.
+/*
+/* When the \fB-F\fR option is given, the \fIvalue\fR must
+/* specify one or more filenames separated by comma and/or
+/* whitespace; \fBpostmap\fR(1) will concatenate the file
+/* content (with a newline character inserted between files)
+/* and will store the base64-encoded result instead of the
+/* \fIvalue\fR.
+/*
+/* When the \fIkey\fR specifies email address information, the
+/* localpart should be enclosed with double quotes if required
+/* by RFC 5322. For example, an address localpart that contains
+/* ";", or a localpart that starts or ends with ".".
+/*
+/* By default the lookup key is mapped to lowercase to make
+/* the lookups case insensitive; as of Postfix 2.3 this case
+/* folding happens only with tables whose lookup keys are
+/* fixed-case strings such as btree:, dbm: or hash:. With
+/* earlier versions, the lookup key is folded even with tables
+/* where a lookup field can match both upper and lower case
+/* text, such as regexp: and pcre:. This resulted in loss of
+/* information with $\fInumber\fR substitutions.
+/* COMMAND-LINE ARGUMENTS
+/* .ad
+/* .fi
+/* .IP \fB-b\fR
+/* Enable message body query mode. When reading lookup keys
+/* from standard input with "\fB-q -\fR", process the input
+/* as if it is an email message in RFC 5322 format. Each line
+/* of body content becomes one lookup key.
+/* .sp
+/* By default, the \fB-b\fR option starts generating lookup
+/* keys at the first non-header line, and stops when the end
+/* of the message is reached.
+/* To simulate \fBbody_checks\fR(5) processing, enable MIME
+/* parsing with \fB-m\fR. With this, the \fB-b\fR option
+/* generates no body-style lookup keys for attachment MIME
+/* headers and for attached message/* headers.
+/* .sp
+/* NOTE: with "smtputf8_enable = yes", the \fB-b\fR option
+/* disables UTF-8 syntax checks on query keys and lookup
+/* results. Specify the \fB-U\fR option to force UTF-8
+/* syntax checks anyway.
+/* .sp
+/* This feature is available in Postfix version 2.6 and later.
+/* .IP "\fB-c \fIconfig_dir\fR"
+/* Read the \fBmain.cf\fR configuration file in the named directory
+/* instead of the default configuration directory.
+/* .IP "\fB-d \fIkey\fR"
+/* Search the specified maps for \fIkey\fR and remove one entry per map.
+/* The exit status is zero when the requested information was found.
+/*
+/* If a key value of \fB-\fR is specified, the program reads key
+/* values from the standard input stream. The exit status is zero
+/* when at least one of the requested keys was found.
+/* .IP \fB-f\fR
+/* Do not fold the lookup key to lower case while creating or querying
+/* a table.
+/*
+/* With Postfix version 2.3 and later, this option has no
+/* effect for regular expression tables. There, case folding
+/* is controlled by appending a flag to a pattern.
+/* .IP \fB-F\fR
+/* When querying a map, or listing a map, base64-decode each
+/* value. When creating a map from source file, process each
+/* value as a list of filenames, concatenate the content of
+/* those files, and store the base64-encoded result instead
+/* of the value (see INPUT FILE FORMAT for details).
+/* .sp
+/* This feature is available in Postfix version 3.4 and later.
+/* .IP \fB-h\fR
+/* Enable message header query mode. When reading lookup keys
+/* from standard input with "\fB-q -\fR", process the input
+/* as if it is an email message in RFC 5322 format. Each
+/* logical header line becomes one lookup key. A multi-line
+/* header becomes one lookup key with one or more embedded
+/* newline characters.
+/* .sp
+/* By default, the \fB-h\fR option generates lookup keys until
+/* the first non-header line is reached.
+/* To simulate \fBheader_checks\fR(5) processing, enable MIME
+/* parsing with \fB-m\fR. With this, the \fB-h\fR option also
+/* generates header-style lookup keys for attachment MIME
+/* headers and for attached message/* headers.
+/* .sp
+/* NOTE: with "smtputf8_enable = yes", the \fB-b\fR option
+/* option disables UTF-8 syntax checks on query keys and
+/* lookup results. Specify the \fB-U\fR option to force UTF-8
+/* syntax checks anyway.
+/* .sp
+/* This feature is available in Postfix version 2.6 and later.
+/* .IP \fB-i\fR
+/* Incremental mode. Read entries from standard input and do not
+/* truncate an existing database. By default, \fBpostmap\fR(1) creates
+/* a new database from the entries in \fBfile_name\fR.
+/* .IP \fB-m\fR
+/* Enable MIME parsing with "\fB-b\fR" and "\fB-h\fR".
+/* .sp
+/* This feature is available in Postfix version 2.6 and later.
+/* .IP \fB-N\fR
+/* Include the terminating null character that terminates lookup keys
+/* and values. By default, \fBpostmap\fR(1) does whatever is
+/* the default for
+/* the host operating system.
+/* .IP \fB-n\fR
+/* Don't include the terminating null character that terminates lookup
+/* keys and values. By default, \fBpostmap\fR(1) does whatever
+/* is the default for
+/* the host operating system.
+/* .IP \fB-o\fR
+/* Do not release root privileges when processing a non-root
+/* input file. By default, \fBpostmap\fR(1) drops root privileges
+/* and runs as the source file owner instead.
+/* .IP \fB-p\fR
+/* Do not inherit the file access permissions from the input file
