580 | Furthermore you need access to a news server to actually post FAQs. | |
581 | ||
582 | =head1 DESCRIPTION | |
583 | ||
584 | B<yapfaq> posts (one or more) FAQs to Usenet with a certain posting | |
585 | frequency (every n days, weeks, months or years), adding all necessary | |
586 | headers as defined in its config file (by default F<yapfaq.cfg>). | |
587 | ||
588 | =head2 Configuration | |
589 | ||
590 | F<yapfaq.cfg> consists of one or more blocks, separated by C<=====> on | |
591 | a single line, each containing the configuration for one FAQ as a set | |
592 | of definitions in the form of I<param = value>. | |
593 | ||
594 | =over 4 | |
595 | ||
596 | =item B<Name> = I<project name> | |
597 | ||
598 | A name referring to your FAQ, also used for generation of a Message-ID. | |
599 | ||
600 | This value must be set. | |
601 | ||
602 | =item B<File> = I<file name> | |
603 | ||
604 | A file containing the message body of your FAQ and all pseudo headers | |
605 | (subheaders in the news.answers style). | |
606 | ||
607 | This value must be set. | |
608 | ||
609 | =item B<Posting-frequency> = I<time period> | |
610 | ||
611 | The posting frequency defines how often your FAQ will be posted. | |
612 | B<yapfaq> will only post your FAQ if this period of time has passed | |
613 | since the last posting. | |
614 | ||
615 | You can declare that time period either in I<B<d>ays> or I<B<w>weeks> | |
616 | or I<B<m>onths> or I<B<y>ears>. | |
617 | ||
618 | This value must be set. | |
619 | ||
620 | =item B<Expires> = I<time period> | |
621 | ||
622 | The period of time after which your message will expire. An Expires | |
623 | header will be calculated adding this time period to today's date. | |
624 | ||
625 | You can declare this time period either in I<B<d>ays> or I<B<w>weeks> | |
626 | or I<B<m>onths> or I<B<y>ears>. | |
627 | ||
628 | This setting is optional; the default is 3 months. | |
629 | ||
630 | =item B<From> = I<author> | |
631 | ||
632 | The author of your FAQ as it will appear in the From header of the | |
633 | message. | |
634 | ||
635 | This value must be set. | |
636 | ||
637 | =item B<Subject> = I<subject> | |
638 | ||
639 | The title of your FAQ as it will appear in the Subject header of the | |
640 | message. | |
641 | ||
642 | You may use the special string C<%LM> which will be replaced with | |
643 | the contents of the Last-Modified subheader in your I<File>. | |
644 | ||
645 | This value must be set. | |
646 | ||
647 | =item B<NGs> = I<newsgroups> | |
648 | ||
649 | A comma-separated list of newsgroup(s) to post your FAQ to as it will | |
650 | appear in the Newsgroups header of the message. | |
651 | ||
652 | This value must be set. | |
653 | ||
654 | =item B<Fup2> = I<newsgroup | poster> | |
655 | ||
656 | A comma-separated list of newsgroup(s) or the special string I<poster> | |
657 | as it will appear in the Followup-To header of the message. | |
658 | ||
659 | This setting is optional. | |
660 | ||
661 | =item B<MID-Format> = I<pattern> | |
662 | ||
663 | A pattern from which the message ID is generated as it will appear in | |
664 | the Message-ID header of the message. | |
665 | ||
666 | You may use the special strings C<%n> for the I<Name> of your project, | |
667 | C<%d> for the date the message is posted, C<%m> for the month and | |
668 | C<%y> for the year, respectively. | |
669 | ||
670 | This value must be set. | |
671 | ||
672 | =item B<Supersede> = I<yes> | |
673 | ||
674 | Add Supersedes header to the message containing the Message-ID header | |
675 | of the last posting. | |
676 | ||
677 | This setting is optional; you should set it to yes or leave it out. | |
678 | ||
679 | =item B<ExtraHeader> = I<additional headers> | |
680 | ||
681 | The contents of I<ExtraHeader> is added verbatim to the headers of | |
682 | your message so you can add custom headers like Approved. | |
683 | ||
684 | This setting is optional. | |

783 | do without embarassing yourself on Usenet. The status files are not | |
784 | updated when this option is given. | |
785 | ||
786 | You may want to use this with the B<-f> option (see below). | |
787 | ||
788 | =item B<-f> I<project name> | |
789 | ||
790 | Just deal with one FAQ only. | |
791 | ||
792 | By default B<yapfaq> will work on all FAQs that are defined in | |
793 | F<yapfaq.cfg>, check whether they are due for posting and - if they | |
794 | are - post them. Consequently when the B<-p> option is set all FAQs | |
795 | will be posted unconditionally. That may not be what you want to | |
796 | achieve, so you can limit the operation of B<yapfaq> to the named FAQ | |
797 | only. | |

800 | ||
801 | Instead of posting the article(s) to Usenet pipe them to the external | |
802 | I<program> on STDIN (which may post the article(s) then). A return | |
803 | value of 0 will be considered success. | |

807 | =head1 EXAMPLES | |
808 | ||
809 | Post all FAQs that are due for posting: | |
810 | ||
811 | yapfaq | |
812 | ||
813 | Do a dry run, showing which FAQs would be posted: | |
814 | ||
815 | yapfaq -dv | |
816 | ||
817 | Do a test run and print on STDOUT what the FAQ I<myfaq> would look | |
818 | like when posted, regardless whether it is due for posting or not: | |
819 | ||
820 | yapfaq -pt CONSOLE -f myfaq | |
821 | ||
822 | Do a "real" test run and post the FAQ I<myfaq> to I<de.test>, but only | |
823 | if it is due: | |
824 | ||
825 | yapfaq -t de.test -f myfaq | |
826 | ||
827 | =head1 ENVIRONMENT | |
828 | ||
829 | There are no special environment variables used by B<yapfaq>. | |

831 | =head1 FILES | |
832 | ||
833 | =over 4 | |
834 | ||
835 | =item F<yapfaq.pl> | |
836 | ||
837 | The script itself. | |
838 | ||
839 | =item F<yapfaq.cfg> | |
840 | ||
841 | Configuration file for B<yapfaq>. | |
842 | ||
843 | =item F<*.cfg> | |
844 | ||
845 | Status data on FAQs. | |
846 | ||
847 | The status files will be created on successful posting if they don't | |
848 | already exist. The first line of the file will be the date of the last | |
849 | time the FAQ was posted and the second line will be the message ID of | |
850 | the last post of that FAQ. | |
