| 574 | |
| 575 | Furthermore you need access to a news server to actually post FAQs. |
| 576 | |
| 577 | =head1 DESCRIPTION |
| 578 | |
| 579 | B<yapfaq> posts (one or more) FAQs to Usenet with a certain posting |
| 580 | frequency (every n days, weeks, months or years), adding all necessary |
| 581 | headers as defined in its config file (by default F<yapfaq.cfg>). |
| 582 | |
| 583 | =head2 Configuration |
| 584 | |
| 585 | F<yapfaq.cfg> consists of one or more blocks, separated by C<=====> on |
| 586 | a single line, each containing the configuration for one FAQ as a set |
| 587 | of definitions in the form of I<param = value>. |
| 588 | |
| 589 | =over 4 |
| 590 | |
| 591 | =item B<Name> = I<project name> |
| 592 | |
| 593 | A name referring to your FAQ, also used for generation of a Message-ID. |
| 594 | |
| 595 | This value must be set. |
| 596 | |
| 597 | =item B<File> = I<file name> |
| 598 | |
| 599 | A file containing the message body of your FAQ and all pseudo headers |
| 600 | (subheaders in the news.answers style). |
| 601 | |
| 602 | This value must be set. |
| 603 | |
| 604 | =item B<Posting-frequency> = I<time period> |
| 605 | |
| 606 | The posting frequency defines how often your FAQ will be posted. |
| 607 | B<yapfaq> will only post your FAQ if this period of time has passed |
| 608 | since the last posting. |
| 609 | |
| 610 | You can declare that time period either in I<B<d>ays> or I<B<w>weeks> |
| 611 | or I<B<m>onths> or I<B<y>ears>. |
| 612 | |
| 613 | This value must be set. |
| 614 | |
| 615 | =item B<Expires> = I<time period> |
| 616 | |
| 617 | The period of time after which your message will expire. An Expires |
| 618 | header will be calculated adding this time period to today's date. |
| 619 | |
| 620 | You can declare this time period either in I<B<d>ays> or I<B<w>weeks> |
| 621 | or I<B<m>onths> or I<B<y>ears>. |
| 622 | |
| 623 | This setting is optional; the default is 3 months. |
| 624 | |
| 625 | =item B<From> = I<author> |
| 626 | |
| 627 | The author of your FAQ as it will appear in the From header of the |
| 628 | message. |
| 629 | |
| 630 | This value must be set. |
| 631 | |
| 632 | =item B<Subject> = I<subject> |
| 633 | |
| 634 | The title of your FAQ as it will appear in the Subject header of the |
| 635 | message. |
| 636 | |
| 637 | You may use the special string C<%LM> which will be replaced with |
| 638 | the contents of the Last-Modified subheader in your I<File>. |
| 639 | |
| 640 | This value must be set. |
| 641 | |
| 642 | =item B<NGs> = I<newsgroups> |
| 643 | |
| 644 | A comma-separated list of newsgroup(s) to post your FAQ to as it will |
| 645 | appear in the Newsgroups header of the message. |
| 646 | |
| 647 | This value must be set. |
| 648 | |
| 649 | =item B<Fup2> = I<newsgroup | poster> |
| 650 | |
| 651 | A comma-separated list of newsgroup(s) or the special string I<poster> |
| 652 | as it will appear in the Followup-To header of the message. |
| 653 | |
| 654 | This setting is optional. |
| 655 | |
| 656 | =item B<MID-Format> = I<pattern> |
| 657 | |
| 658 | A pattern from which the message ID is generated as it will appear in |
| 659 | the Message-ID header of the message. |
| 660 | |
| 661 | You may use the special strings C<%n> for the I<Name> of your project, |
| 662 | C<%d> for the date the message is posted, C<%m> for the month and |
| 663 | C<%y> for the year, respectively. |
| 664 | |
| 665 | This value must be set. |
| 666 | |
| 667 | =item B<Supersede> = I<yes> |
| 668 | |
| 669 | Add Supersedes header to the message containing the Message-ID header |
| 670 | of the last posting. |
| 671 | |
| 672 | This setting is optional; you should set it to yes or leave it out. |
| 673 | |
| 674 | =item B<ExtraHeader> = I<additional headers> |
| 675 | |
| 676 | The contents of I<ExtraHeader> is added verbatim to the headers of |
| 677 | your message so you can add custom headers like Approved. |
| 678 | |
| 679 | This setting is optional. |

| 696 | # time period after which the posting should expire |
| 697 | # use (d)ay OR (w)eek OR (m)onth OR (y)ear |
| 698 | Expires = '3m' |

| 701 | From = 'test@domain.invalid' |
| 702 | |
| 703 | # header "Subject:" |

| 706 | Subject = 'test noreply ignore' |

| 714 | |
| 715 | # Message-ID ("%n" is $Name) |
| 716 | MID-Format = '<%n-%d.%m.%y@domain.invalid>' |
| 717 | |
| 718 | # Supersede last posting? |
| 719 | Supersede = yes |
| 720 | |
| 721 | # extra headers (appended verbatim) |
| 722 | # use this for custom headers like "Approved:" |
| 723 | ExtraHeader = 'Approved: moderator@domain.invalid |
| 724 | X-Header: Some text' |
| 725 | |
| 726 | # other projects may follow separated with "=====" |
| 727 | ===== |
| 728 | |
| 729 | Name = 'othertest' |
| 730 | File = 'test.txt' |
| 731 | Posting-frequency = '2m' |
| 732 | From = 'My Name <my.name@domain.invalid>' |
| 733 | Subject = 'Test of yapfag <%LM>' |
| 734 | NGs = 'de.test,de.alt.test' |
| 735 | Fup2 = 'de.test' |
| 736 | MID-Format = '<%n-%m.%y@domain.invalid>' |
| 737 | Supersede = yes |
| 738 | |
| 739 | Information about the last post and about how to form message IDs for |
| 740 | posts is stored in a file named F<I<project name>.cfg> which will be |
| 741 | generated if it does not exist. Each of those status files will |
| 742 | contain two lines, the first being the date of the last time the FAQ |
| 743 | was posted and the second being the message ID of that incarnation. |
| 744 | |
| 745 | =head1 OPTIONS |
| 746 | |
| 747 | =over 3 |
| 748 | |
| 749 | =item B<-V> (version) |
| 750 | |
| 751 | Print out version and copyright information on B<yapfaq> and exit. |
| 752 | |
| 753 | =item B<-h> (help) |
| 754 | |
| 755 | Print this man page and exit. |
| 756 | |
| 757 | =item B<-v> (verbose) |
| 758 | |
| 759 | Print out status information while running to STDOUT. |
| 760 | |
| 761 | =item B<-p> (post unconditionally) |
| 762 | |
| 763 | Post (all) FAQs unconditionally ignoring the posting frequency setting. |
| 764 | |
| 765 | You may want to use this with the B<-f> option (see below). |
| 766 | |
| 767 | =item B<-d> (dry run) |
| 768 | |
| 769 | Start B<yapfaq> in simulation mode, i.e. don't post anything and don't |
| 770 | update any status information. |
| 771 | |
| 772 | =item B<-t> I<newsgroup(s) | CONSOLE> (test) |
| 773 | |
| 774 | Don't post to the newsgroups defined in F<yqpfaq.cfg>, but to the |
| 775 | newsgroups given after B<-t> as a comma-separated list or print the |
| 776 | FAQs to STDOUT separated by lines of dashes if the special string |
| 777 | C<CONSOLE> is given. This can be used to preview what B<yapfaq> would |
| 778 | do without embarassing yourself on Usenet. The status files are not |
| 779 | updated when this option is given. |
| 780 | |
| 781 | You may want to use this with the B<-f> option (see below). |
| 782 | |
| 783 | =item B<-f> I<project name> |
| 784 | |
| 785 | Just deal with one FAQ only. |
| 786 | |
| 787 | By default B<yapfaq> will work on all FAQs that are defined in |
| 788 | F<yapfaq.cfg>, check whether they are due for posting and - if they |
| 789 | are - post them. Consequently when the B<-p> option is set all FAQs |
| 790 | will be posted unconditionally. That may not be what you want to |
| 791 | achieve, so you can limit the operation of B<yapfaq> to the named FAQ |
| 792 | only. |
| 793 | |
| 794 | =item B<-s> I<program> (pipe to script) |
| 795 | |
| 796 | Instead of posting the article(s) to Usenet pipe them to the external |
| 797 | I<program> on STDIN (which may post the article(s) then). A return |
| 798 | value of 0 will be considered success. |
| 799 | |
| 800 | =back |
| 801 | |
| 802 | =head1 EXAMPLES |
| 803 | |
| 804 | Post all FAQs that are due for posting: |
| 805 | |
| 806 | yapfaq |
| 807 | |
| 808 | Do a dry run, showing which FAQs would be posted: |
| 809 | |
| 810 | yapfaq -dv |
| 811 | |
| 812 | Do a test run and print on STDOUT what the FAQ I<myfaq> would look |
| 813 | like when posted, regardless whether it is due for posting or not: |
| 814 | |
| 815 | yapfaq -pt CONSOLE -f myfaq |
| 816 | |
| 817 | Do a "real" test run and post the FAQ I<myfaq> to I<de.test>, but only |
| 818 | if it is due: |
| 819 | |
| 820 | yapfaq -t de.test -f myfaq |
| 821 | |
| 822 | =head1 ENVIRONMENT |
| 823 | |
| 824 | There are no special environment variables used by B<yapfaq>. |
| 825 | |
| 826 | =head1 FILES |
| 827 | |
| 828 | =over 4 |
| 829 | |
| 830 | =item F<yapfaq.pl> |
| 831 | |
| 832 | The script itself. |
| 833 | |
| 834 | =item F<yapfaq.cfg> |
| 835 | |
| 836 | Configuration file for B<yapfaq>. |
| 837 | |
| 838 | =item F<*.cfg> |
| 839 | |
| 840 | Status data on FAQs. |
| 841 | |
| 842 | The status files will be created on successful posting if they don't |
| 843 | already exist. The first line of the file will be the date of the last |
| 844 | time the FAQ was posted and the second line will be the message ID of |
| 845 | the last post of that FAQ. |
| 846 | |
