-** The first table describes available mailers. This is
-** just a list of argument vectors, with the following
-** codes embedded:
-** $u -- insert the user name.
-** $h -- insert the host name.
-** $f -- insert the from person name.
-** $c -- insert the hop count.
-** This stuff is interpreted in buildmail. There are two
-** important conventions here: entry zero must be the
-** local mailer & entry one must be the shell.
-**
-** The second table gives a list of special characters. This
-** table is scanned linearly by parse() until an entry is
-** found using one of the magic characters. Other fields
-** give more information on how to handle it.
-**
-** Defined Constants:
-** M_* -- indices into Mailer, used only in this module.
-**
-** Defines:
-** Mailer -- the mailer descriptor table.
-** ParseTab -- the parse table.

-** History:
-** 3/5/80 -- Generalized to use <whoami.h>.
-** 12/26/79 -- written for Ingres 11/70.
+** Compilation Flags:
+** HASARPA -- set if this machine has a connection to
+** the Arpanet.
+** HASUUCP -- set if this machine has a connection to
+** the UUCP network.
+** NETV6MAIL -- set if you want to use "v6mail" that
+** comes with the Berkeley network. Normally
+** /bin/mail will work fine, but around Berkeley
+** we use v6mail because it is a "fixed target".
+** V6 -- running on a version 6 system. This determines
+** whether to define certain routines between
+** the two systems. If you are running a funny
+** system, e.g., V6 with long tty names, this
+** should be checked carefully.
+**
+** Configuration Variables:
+** ArpaHost -- the name of the host through which arpanet
+** mail will be sent.
+** MyLocName -- the name of the host on a local network.
+** This is used to disambiguate the contents of
+** ArpaHost among many hosts who may be sharing
+** a gateway.
+** Mailer -- a table of mailers known to the system.
+** The fields are:
+** - the pathname of the mailer.
+** - a list of flags describing the properties
+** of this mailer:
+** M_FOPT -- if set, the mailer has a picky "-f"
+** option. In this mode, the mailer will
+** only accept the "-f" option if the
+** sender is actually "root", "network",
+** and possibly (but not necessarily) if
+** the -f argument matches the real sender.
+** The effect is that if the "-f" option
+** is given to delivermail then it will be
+** passed through (as arguments 1 & 2) to
+** the mailer.
+** M_ROPT -- identical to M_FOPT, except uses
+** -r instead.
+** M_QUIET -- if set, don't print a message if
+** the mailer returns bad status.
+** M_RESTR -- if set, this mailer is restricted
+** to use by "daemon"; otherwise, we do a
+** setuid(getuid()) before calling the
+** mailer.
+** M_HDR -- if set, the mailer wants us to
+** insert a UNIX "From" line before
+** outputing.
+** M_NOHOST -- if set, this mailer doesn't care
+** about the host part (e.g., the local
+** mailer).
+** M_STRIPQ -- if set, strip quote (`"')
+** characters out of parameters as you
+** transliterate them into the argument
+** vector. For example, the local mailer
+** is called directly, so these should be
+** stripped, but the program-mailer (i.e.,
+** csh) should leave them in.
+** - an exit status to use as the code for the
+** error message print if the mailer returns
+** something we don't understand.
+** - A list of names that are to be considered
+** "local" (and hence are stripped off) for
+** this mailer.
+** - An argument vector to be passed to the
+** mailer with the following substitutions:
+** $f - the from person name.
+** $u - the target user name.
+** $h - the target user host.
+** $c - the hop count.
+** >>>>>>>>>> Entry zero must be for the local
+** >> NOTE >> mailer and entry one must be for
+** >>>>>>>>>> the shell.
+** ParseTab -- a table driving the parsing process. Each
+** entry contains:
+** - a character that will trigger this entry.
+** - an index into the Mailer table.
+** - a word of flags, described in dlvrmail.h.
+** - an argument. If we have P_MAP, it is the
+** character to turn the trigger character into.
+** If we have P_MOVE, it is the site to send it
+** to, using the mailer specified above.
