Alberto Bertogli 24af22ac35 docs: Add man pages
This patch adds man pages for chasquid's main commands and
configuration. They are generated using pod2man (commonly used for this,
and included with perl in most distributions).

The generated man pages are included to avoid introducing a dependency
for such simple task, similar to how we handle protocol buffer generated
files.

=head1 NAME
chasquid.conf(5) -- chasquid configuration file
=head1 SYNOPSIS
chasquid.conf(5) is chasquid(1)'s main configuration file.
=head1 DESCRIPTION
The file is in protocol buffers' text format.
Comments start with C<#>. Empty lines are allowed. Values are of the form
C<key: value>. Values can be strings (quoted), integers, or booleans (C<true> or
C<false>).
Some values might be repeated, for example the listening addresses.
=head1 OPTIONS
=over 8
=item B<hostname> (string):
Default hostname to use when saying hello. This is used to say hello to
clients, for aesthetic purposes. Default: the system's hostname.
=item B<max_data_size_mb> (int):
Maximum email size, in megabytes. Default: 50.
=item B<smtp_address> (repeated string):
Addresses to listen on for SMTP. Default: "systemd", which means systemd
passes sockets to us. systemd sockets must be named with
B<FileDescriptorName=smtp>.
=item B<submission_address> (repeated string):
Addresses to listen on for submission. Default: "systemd", which means
systemd passes sockets to us. systemd sockets must be named with
B<FileDescriptorName=submission>.
=item B<monitoring_address> (string):
Address for the monitoring HTTP server. Do NOT expose this to the public
internet. Default: no monitoring server.
=item B<mail_delivery_agent_bin> (string):
Mail delivery agent (MDA, also known as LDA) to use. This should point
to the binary to use to deliver email to local users. The content of the
email will be passed via stdin. If it exits unsuccessfully, we assume
the mail was not delivered. Default: F<maildrop>.
=item B<mail_delivery_agent_args> (repeated string):
Command line arguments for the mail delivery agent. One per argument.
Some replacements will be done.
On an email sent from marsnik@mars to venera@venus:
%from% -> from address (marsnik@mars)
%from_user% -> from user (marsnik)
%from_domain% -> from domain (mars)
%to% -> to address (venera@venus)
%to_user% -> to user (venera)
%to_domain% -> to domain (venus)
Default: C<"-f", "%from%", "-d", "%to_user%"> (adequate for procmail and
maildrop).
=item B<data_dir> (string):
Directory where we store our persistent data. Default:
F</var/lib/chasquid>.
=item B<suffix_separators> (string):
Suffix separator, to perform suffix removal of local users. For
example, if you set this to C<-+>, email to local user C<user-blah> and
C<user+blah> will be delivered to C<user>. Including C<+> is strongly
encouraged, as it is assumed for email forwarding. Default: C<+>.
=item B<drop_characters> (string):
Characters to drop from the user part on local emails. For example, if
you set this to C<._>, email to local user C<u.se_r> will be delivered to
C<user>. Default: C<.>.
=item B<mail_log_path> (string):
Path where to write the mail log to. If C<< <syslog> >>, log using the
syslog (at C<MAIL|INFO> priority). Default: C<< <syslog> >>.
