=head1 NAME
yapfaq - Post Usenet FAQs I<(yet another postfaq)>
=head1 SYNOPSIS
B<yapfaq> [B<-Vhvpd>] [B<-t> I<newsgroups> | CONSOLE] [B<-f> I<project name>] [B<-s> I<program>] [B<-c> I<.rc file>]
=head1 REQUIREMENTS
=over 2
=item -
Perl 5.8 or later
=item -
Net::NNTP
=item -
Date::Calc
=item -
Getopt::Std
=back
Furthermore you need access to a news server to actually post FAQs.
=head1 DESCRIPTION
B<yapfaq> posts (one or more) FAQs to Usenet with a certain posting
frequency (every n days, weeks, months or years), adding all necessary
headers as defined in its config file (by default F<yapfaq.cfg>).
=head2 Configuration
F<yapfaq.cfg> consists of one or more blocks, separated by C<=====> on
a single line, each containing the configuration for one FAQ as a set
of definitions in the form of I<param = value>. Everything after a "#"
sign is ignored so you may comment your configuration file.
=over 4
=item B<Name> = I<project name>
A name referring to your FAQ, also used for generation of a Message-ID.
This value must be set.
=item B<File> = I<file name>
A file containing the message body of your FAQ and all pseudo headers
(subheaders in the news.answers style).
This value must be set.
=item B<Posting-frequency> = I<time period>
The posting frequency defines how often your FAQ will be posted.
B<yapfaq> will only post your FAQ if this period of time has passed
since the last posting.
You can declare that time period either in I<B<d>ays> or I<B<w>weeks>
or I<B<m>onths> or I<B<y>ears>.
This value must be set.
=item B<Expires> = I<time period> (optional)
The period of time after which your message will expire. An Expires
header will be calculated adding this time period to today's date.
You can declare this time period either in I<B<d>ays> or I<B<w>weeks>
or I<B<m>onths> or I<B<y>ears>.
This setting is optional; the default is 3 months.
=item B<From> = I<author>
The author of your FAQ as it will appear in the From header of the
message.
This value must be set.
=item B<Subject> = I<subject>
The title of your FAQ as it will appear in the Subject header of the
message.
You may use the special string C<%LM> which will be replaced with
the contents of the Last-Modified subheader in your I<File>.
This value must be set.
=item B<NGs> = I<newsgroups>
A comma-separated list of newsgroup(s) to post your FAQ to as it will
appear in the Newsgroups header of the message.
This value must be set.
=item B<Fup2> = I<newsgroup | poster> (optional)
A comma-separated list of newsgroup(s) or the special string I<poster>
as it will appear in the Followup-To header of the message.
This setting is optional.
=item B<MID-Format> = I<pattern> (optional)
A pattern from which the message ID is generated as it will appear in
the Message-ID header of the message.
You may use the special strings C<%n> for the I<Name> of your project,
C<%d> for the date the message is posted, C<%m> for the month, C<%y>
for the year and C<%t> for a time stamp (number of seconds since the
epoch), respectively.
This setting is optional; the default is '<%n-%y-%m-%d@I<YOURHOST>>'
where I<YOURHOST> is the fully qualified domain name (FQDN) of the
host B<yapfaq> is running on. Obviously that will only work if you
have defined a reasonable hostname that the hostfqdn() function of
Net::Domain can return.
=item B<Charset> = I<encoding> (optional)
The character encoding of your FAQ. This setting is optional, but
should match the encoding of your FAQ B<File>. Default is set to
I<UTF-8>.
This setting is copied verbatim to the I<Content-Type> header.
=item B<Supersede> = I<yes> (optional)
Add Supersedes header to the message containing the Message-ID header
of the last posting.
This setting is optional; you should set it to yes or leave it out.
=item B<ExtraHeader> = I<additional headers> (optional)
The contents of I<ExtraHeader> is added verbatim to the headers of
your message so you can add custom headers like Approved.
This setting is optional.
=back
=head3 Example configuration file
# name of your project
Name = 'testpost'
# file to post (complete body and pseudo-headers)
# ($File.cfg contains data on last posting and last MID)
File = 'test.txt'
# how often your project should be posted
# use (d)ay OR (w)eek OR (m)onth OR (y)ear
Posting-frequency = '1d'
# time period after which the posting should expire
# use (d)ay OR (w)eek OR (m)onth OR (y)ear
# Expires = '3m'
# header "From:"
From = 'test@domain.invalid'
# header "Subject:"
# (may contain "%LM" which will be replaced by the contents of the
# Last-Modified pseudo header).
Subject = 'test noreply ignore'
# comma-separated list of newsgroup(s) to post to
# (header "Newsgroups:")
NGs = 'de.test'
# header "Followup-To:"
# Fup2 = 'poster'
# Message-ID ("%n" is $Name)
# MID-Format = '<%n-%d.%m.%y@domain.invalid>'
# Character Encoding
# This setting is optional. Default: UTF-8
# Charset = ISO-8859-15
# Supersede last posting?
Supersede = yes
# extra headers (appended verbatim)
# use this for custom headers like "Approved:"
ExtraHeader = 'Approved: moderator@domain.invalid
X-Header: Some text'
# other projects may follow separated with "====="
=====
Name = 'othertest'
File = 'test.txt'
Posting-frequency = '2m'
From = 'My Name <my.name@domain.invalid>'
Subject = 'Test of yapfag <%LM>'
NGs = 'de.test,de.alt.test'
Fup2 = 'de.test'
MID-Format = '<%n-%m.%y@domain.invalid>'
Supersede = yes
=head3 Status Information
Information about the last post and about how to form message IDs for
posts is stored in a file named F<I<project name>.cfg> which will be
generated if it does not exist. Each of those status files will
contain two lines, the first being the date of the last time the FAQ
was posted and the second being the message ID of that incarnation.
=head2 Runtime Configuration
Apart from configuring which FAQ(s) to post you may (re)set some
runtime configuration variables via the .rcfile (by default
F<.yapfaqrc>). F<.yapfaqrc> must contain one definition in the form of
I<param = value> on each line; everything after a "#" sign is ignored.
If you omit some settings they will be set to default values hardcoded
in F<yapfaq.pl>.
B<Please note that all parameter names are case-sensitive!>
=over 4
=item B<NNTPServer> = I<NNTP server> (mandatory)
Host name of the NNTP server to post to. Must be set (or omitted; the
default is "localhost"); if set to en empty string, B<yapfaq> falls
back to Perl's build-in defaults (contents of environment variables
NNTPSERVER and NEWSHOST; if not set, default from Net::Config; if not
set, "news" is used).
=item B<NNTPUser> = I<user name> (optional)
User name used for authentication with the NNTP server (I<AUTHINFO
USER>).
This setting is optional; if it is not set, I<NNTPPass> is ignored and
no authentication is tried.
=item B<NNTPPass> = I<password> (optional)
Password used for authentication with the NNTP server (I<AUTHINFO
PASS>).
This setting is optional; it must be set if I<NNTPUser> is present.
=item B<Sender> = I<Sender header> (optional)
The Sender header that will be added to every posted message.
This setting is optional.
=item B<ConfigFile> = I<configuration file> (mandatory)
The configuration file defining the FAQ(s) to post. Must be set (or
omitted; the default is "yapfaq.cfg").
=item B<Program> = I<file name> (optional)
A program the article is piped to instead of posting it to Usenet.
See option "-f" below (which takes preference).
This setting is optional.
=back
=head3 Example runtime configuration file
NNTPServer = 'localhost'
NNTPUser = ''
NNTPPass = ''
Sender = ''
ConfigFile = 'yapfaq.cfg'
Program = ''
=head3 Using more than one runtime configuration
You may use more than one runtime configuration file with the B<-c>
option (see below).
=head1 OPTIONS
=over 3
=item B<-V> (version)
Print out version and copyright information on B<yapfaq> and exit.
=item B<-h> (help)
Print this man page and exit.
=item B<-v> (verbose)
Print out status information while running to STDOUT.
=item B<-p> (post unconditionally)
Post (all) FAQs unconditionally ignoring the posting frequency setting.
You may want to use this with the B<-f> option (see below).
=item B<-d> (dry run)
Start B<yapfaq> in simulation mode, i.e. don't post anything and don't
update any status information.
=item B<-t> I<newsgroup(s) | CONSOLE> (test)
Don't post to the newsgroups defined in F<yqpfaq.cfg>, but to the
(test) newsgroup(s) given after B<-t> as a comma-separated list or
print the FAQs to STDOUT separated by lines of dashes if the special
string C<CONSOLE> is given. This can be used to preview what
B<yapfaq> would do without embarassing yourself on Usenet.
The status files are not updated when this option is given.
When this option is used to post to some other newsgroup(s), a(nother)
timestamp is added to the Message-ID header and the Supersedes header
is replaced by a special X-Supersedes header.
You may want to use this with the B<-f> option (see below).
=item B<-f> I<project name>
Just deal with one FAQ only.
By default B<yapfaq> will work on all FAQs that are defined in
F<yapfaq.cfg>, check whether they are due for posting and - if they
are - post them. Consequently when the B<-p> option is set all FAQs
will be posted unconditionally. That may not be what you want to
achieve, so you can limit the operation of B<yapfaq> to the named FAQ
only.
=item B<-s> I<program> (pipe to script)
Instead of posting the article(s) to Usenet pipe them to the external
I<program> on STDIN (which may post the article(s) then). A return
value of 0 will be considered success.
For example, you may want to use the I<inews> utility from the INN package
or the much more powerful replacement I<tinews.pl> from
I<ftp://ftp.tin.org/tin/tools/tinews.pl> which is able to sign postings.
If I<Program> is also defined in the runtime configuration file (by default
F<.yapfaqrc>), B<-s> takes preference.
=item B<-c> I<.rc file>
Load another runtime configuration file (.rc file) than F<.yaofaq.rc>.
You may for example define another usenet server to post your FAQ(s)
to or load another configuration file defining (an)other FAQ(s).

=head1 INSTALLATION
Just copy the contents of the tarball in some directory and get started.
You can post your first test with
yapfaq -c .yapfaqrc.sample
or copy F<.yapfaqrc.sample> to F<.yapfaqrc> and F<yapfaq.cfg.sample>
to F<yapfaq.cfg>, edit those files and get really started!
=back
=head1 EXAMPLES
Post all FAQs that are due for posting:
yapfaq
Do a dry run, showing which FAQs would be posted:
yapfaq -dv
Do a test run and print on STDOUT what the FAQ I<myfaq> would look
like when posted, regardless whether it is due for posting or not:
yapfaq -pt CONSOLE -f myfaq
Do a "real" test run and post the FAQ I<myfaq> to I<de.test>, but only
if it is due:
yapfaq -t de.test -f myfaq
Post all FAQs (that are due for posting) using inews from INN:
yapfaq -s inews
Do a dry run using a runtime configuration from .alternaterc, showing
which FAQs would be posted:
yapfaq -dvc .alternaterc
=head1 ENVIRONMENT
=over 4
=item NNTPSERVER
The default NNTP server to post to, used by the Net::NNTP module. You
can also specify the server using the runtime configuration file (by
default F<.yapfaqrc>).
=back
=head1 FILES
=over 4
=item F<yapfaq.pl>
The script itself.
=item F<.yapfaqrc>
Runtime configuration file for B<yapfaq>.
=item F<yapfaq.cfg>
Configuration file for B<yapfaq>.
=item F<*.cfg>
Status data on FAQs.
The status files will be created on successful posting if they don't
already exist. The first line of the file will be the date of the last
time the FAQ was posted and the second line will be the message ID of
the last post of that FAQ.
