426
427=head1 DESCRIPTION
428
429B<yapfaq> posts (one or more) FAQs to Usenet with a certain posting
430frequency (every n days, weeks, months or years), adding all necessary
431headers as defined in its config file (by default F<yapfaq.cfg>).
432
433=head2 Configuration
434
435F<yapfaq.cfg> consists of one or more blocks, separated by C<=====> on
436a single line, each containing the configuration for one FAQ as a set
437of definitions in the form of I<param = value>. Everything after a "#"
438sign is ignored so you may comment your configuration file.
439
440=over 4
441
442=item B<Name> = I<project name>
443
444A name referring to your FAQ, also used for generation of a Message-ID.
445
446This value must be set.
447
448=item B<File> = I<file name>
449
450A file containing the message body of your FAQ and all pseudo headers
451(subheaders in the news.answers style).
452
453This value must be set.
454
455=item B<Posting-frequency> = I<time period>
456
457The posting frequency defines how often your FAQ will be posted.
458B<yapfaq> will only post your FAQ if this period of time has passed
459since the last posting.
460
461You can declare that time period either in I<B<d>ays> or I<B<w>weeks>
462or I<B<m>onths> or I<B<y>ears>.
463
464This value must be set.
465
466=item B<Expires> = I<time period> (optional)
467
468The period of time after which your message will expire. An Expires
469header will be calculated adding this time period to today's date.
470
471You can declare this time period either in I<B<d>ays> or I<B<w>weeks>
472or I<B<m>onths> or I<B<y>ears>.
473
474This setting is optional; the default is 3 months.
475
476=item B<From> = I<author>
477
478The author of your FAQ as it will appear in the From header of the
479message.
480
481This value must be set.
482
483=item B<Subject> = I<subject>
484
485The title of your FAQ as it will appear in the Subject header of the
486message.
487
488You may use the special string C<%LM> which will be replaced with
489the contents of the Last-Modified subheader in your I<File>.
490
491This value must be set.
492
493=item B<NGs> = I<newsgroups>
494
495A comma-separated list of newsgroup(s) to post your FAQ to as it will
496appear in the Newsgroups header of the message.
497
498This value must be set.
499
500=item B<Fup2> = I<newsgroup | poster> (optional)
501
502A comma-separated list of newsgroup(s) or the special string I<poster>
503as it will appear in the Followup-To header of the message.
504
505This setting is optional.
506
507=item B<MID-Format> = I<pattern> (optional)
508
509A pattern from which the message ID is generated as it will appear in
510the Message-ID header of the message.
511
512You may use the special strings C<%n> for the I<Name> of your project,
513C<%d> for the date the message is posted, C<%m> for the month, C<%y>
514for the year and C<%t> for a time stamp (number of seconds since the
515epoch), respectively.
516
517This setting is optional; the default is '<%n-%y-%m-%d@I<YOURHOST>>'
518where I<YOURHOST> is the fully qualified domain name (FQDN) of the
519host B<yapfaq> is running on. Obviously that will only work if you
520have defined a reasonable hostname that the hostfqdn() function of
521Net::Domain can return.
522
523=item B<Supersede> = I<yes> (optional)
524
525Add Supersedes header to the message containing the Message-ID header
526of the last posting.
527
528This setting is optional; you should set it to yes or leave it out.
529
530=item B<ExtraHeader> = I<additional headers> (optional)
531
532The contents of I<ExtraHeader> is added verbatim to the headers of
533your message so you can add custom headers like Approved.

595=head3 Status Information
596
597Information about the last post and about how to form message IDs for
598posts is stored in a file named F<I<project name>.cfg> which will be
599generated if it does not exist. Each of those status files will
600contain two lines, the first being the date of the last time the FAQ
601was posted and the second being the message ID of that incarnation.
602
603=head2 Runtime Configuration
604
605Apart from configuring which FAQ(s) to post you may (re)set some
606runtime configuration variables via the .rcfile (by default
607F<.yapfaqrc>). F<.yapfaqrc> must contain one definition in the form of
608I<param = value> on each line; everything after a "#" sign is ignored.
609
610If you omit some settings they will be set to default values hardcoded
611in F<yapfaq.pl>.

615=over 4
616
617=item B<NNTPServer> = I<NNTP server> (mandatory)
618
619Host name of the NNTP server to post to. Must be set (or omitted; the
620default is "localhost"); if set to en empty string, B<yapfaq> falls
621back to Perl's build-in defaults (contents of environment variables
622NNTPSERVER and NEWSHOST; if not set, default from Net::Config; if not
623set, "news" is used).
624
625=item B<NNTPUser> = I<user name> (optional)
626
627User name used for authentication with the NNTP server (I<AUTHINFO
628USER>).
629
630This setting is optional; if it is not set, I<NNTPPass> is ignored and
631no authentication is tried.
632
633=item B<NNTPPass> = I<password> (optional)
634
635Password used for authentication with the NNTP server (I<AUTHINFO
636PASS>).
637
638This setting is optional; it must be set if I<NNTPUser> is present.
639
640=item B<Sender> = I<Sender header> (optional)
641
642The Sender header that will be added to every posted message.
643
644This setting is optional.
645
646=item B<ConfigFile> = I<configuration file> (mandatory)
647
648The configuration file defining the FAQ(s) to post. Must be set (or
649omitted; the default is "yapfaq.cfg").
650
651=item B<Program> = I<file name> (optional)
652
653A program the article is piped to instead of posting it to Usenet.
654See option "-f" below (which takes preference).

670
671You may use more than one runtime configuration file with the B<-c>
672option (see below).
673
674=head1 OPTIONS
675
676=over 3
677
678=item B<-V> (version)
679
680Print out version and copyright information on B<yapfaq> and exit.
681
682=item B<-h> (help)
683
684Print this man page and exit.
685
686=item B<-v> (verbose)
687
688Print out status information while running to STDOUT.
689
690=item B<-p> (post unconditionally)
691
692Post (all) FAQs unconditionally ignoring the posting frequency setting.
693
694You may want to use this with the B<-f> option (see below).
695
696=item B<-d> (dry run)
697
698Start B<yapfaq> in simulation mode, i.e. don't post anything and don't
699update any status information.
700
701=item B<-t> I<newsgroup(s) | CONSOLE> (test)
702
703Don't post to the newsgroups defined in F<yqpfaq.cfg>, but to the
704(test) newsgroup(s) given after B<-t> as a comma-separated list or
705print the FAQs to STDOUT separated by lines of dashes if the special
706string C<CONSOLE> is given. This can be used to preview what
707B<yapfaq> would do without embarassing yourself on Usenet.
708
709The status files are not updated when this option is given.
710
711When this option is used to post to some other newsgroup(s), a(nother)
712timestamp is added to the Message-ID header and the Supersedes header
713is replaced by a special X-Supersedes header.
714
715You may want to use this with the B<-f> option (see below).
716
717=item B<-f> I<project name>
718
719Just deal with one FAQ only.
720
721By default B<yapfaq> will work on all FAQs that are defined in
722F<yapfaq.cfg>, check whether they are due for posting and - if they
723are - post them. Consequently when the B<-p> option is set all FAQs
724will be posted unconditionally. That may not be what you want to
725achieve, so you can limit the operation of B<yapfaq> to the named FAQ
726only.
727
728=item B<-s> I<program> (pipe to script)
729
730Instead of posting the article(s) to Usenet pipe them to the external
731I<program> on STDIN (which may post the article(s) then). A return
732value of 0 will be considered success.
733
734For example, you may want to use the I<inews> utility from the INN package
735or the much more powerful replacement I<tinews.pl> from
736I<ftp://ftp.tin.org/tin/tools/tinews.pl> which is able to sign postings.
737
738If I<Program> is also defined in the runtime configuration file (by default
739F<.yapfaqrc>), B<-s> takes preference.
740
741=item B<-c> I<.rc file>
742
743Load another runtime configuration file (.rc file) than F<.yaofaq.rc>.
744
745You may for example define another usenet server to post your FAQ(s)
746to or load another configuration file defining (an)other FAQ(s).

749
750=head1 INSTALLATION
751
752Just copy the contents of the tarball in some directory and get started.
753
754You can post your first test with
755
756 yapfaq -c .yapfaqrc.sample
757
758or copy F<.yapfaqrc.sample> to F<.yapfaqrc> and F<yapfaq.cfg.sample>
759to F<yapfaq.cfg>, edit those files and get really started!
760
761=back
762
763=head1 EXAMPLES
764
765Post all FAQs that are due for posting:
766
767 yapfaq
768
769Do a dry run, showing which FAQs would be posted:
770
771 yapfaq -dv
772
773Do a test run and print on STDOUT what the FAQ I<myfaq> would look
774like when posted, regardless whether it is due for posting or not:
775
776 yapfaq -pt CONSOLE -f myfaq
777
778Do a "real" test run and post the FAQ I<myfaq> to I<de.test>, but only
779if it is due:
780
781 yapfaq -t de.test -f myfaq
782
783Post all FAQs (that are due for posting) using inews from INN:
784
785 yapfaq -s inews
786
787Do a dry run using a runtime configuration from .alternaterc, showing
788which FAQs would be posted:
789

822Status data on FAQs.
823
824The status files will be created on successful posting if they don't
825already exist. The first line of the file will be the date of the last
826time the FAQ was posted and the second line will be the message ID of
827the last post of that FAQ.
