| | 545 | |
| | 546 | =head1 DESCRIPTION |
| | 547 | |
| | 548 | B<yapfaq> posts (one or more) FAQs to Usenet with a certain posting |
| | 549 | frequency (every n days, weeks, months or years), adding all necessary |
| | 550 | headers as defined in its config file (by default F<yapfaq.cfg>). |
| | 551 | |
| | 552 | =head2 Configuration |
| | 553 | |
| | 554 | F<yapfaq.cfg> consists of one or more blocks, separated by C<=====> on |
| | 555 | a single line, each containing the configuration for one FAQ as a set |
| | 556 | of definitions in the form of I<param = value>. |
| | 557 | |
| | 558 | =over 4 |
| | 559 | |
| | 560 | =item B<Name> = I<project name> |
| | 561 | |
| | 562 | A name referring to your FAQ, also used for generation of a Message-ID. |
| | 563 | |
| | 564 | This value must be set. |
| | 565 | |
| | 566 | =item B<File> = I<file name> |
| | 567 | |
| | 568 | A file containing the message body of your FAQ and all pseudo headers |
| | 569 | (subheaders in the news.answers style). |
| | 570 | |
| | 571 | This value must be set. |
| | 572 | |
| | 573 | =item B<Posting-frequency> = I<time period> |
| | 574 | |
| | 575 | The posting frequency defines how often your FAQ will be posted. |
| | 576 | B<yapfaq> will only post your FAQ if this period of time has passed |
| | 577 | since the last posting. |
| | 578 | |
| | 579 | You can declare that time period either in I<B<d>ays> or I<B<w>weeks> |
| | 580 | or I<B<m>onths> or I<B<y>ears>. |
| | 581 | |
| | 582 | This value must be set. |
| | 583 | |
| | 584 | =item B<Expires> = I<time period> |
| | 585 | |
| | 586 | The period of time after which your message will expire. An Expires |
| | 587 | header will be calculated adding this time period to today's date. |
| | 588 | |
| | 589 | You can declare this time period either in I<B<d>ays> or I<B<w>weeks> |
| | 590 | or I<B<m>onths> or I<B<y>ears>. |
| | 591 | |
| | 592 | This setting is optional; the default is 3 months. |
| | 593 | |
| | 594 | =item B<From> = I<author> |
| | 595 | |
| | 596 | The author of your FAQ as it will appear in the From header of the |
| | 597 | message. |
| | 598 | |
| | 599 | This value must be set. |
| | 600 | |
| | 601 | =item B<Subject> = I<subject> |
| | 602 | |
| | 603 | The title of your FAQ as it will appear in the Subject header of the |
| | 604 | message. |
| | 605 | |
| | 606 | You may use the special string C<%LM> which will be replaced with |
| | 607 | the contents of the Last-Modified subheader in your I<File>. |
| | 608 | |
| | 609 | This value must be set. |
| | 610 | |
| | 611 | =item B<NGs> = I<newsgroups> |
| | 612 | |
| | 613 | A comma-separated list of newsgroup(s) to post your FAQ to as it will |
| | 614 | appear in the Newsgroups header of the message. |
| | 615 | |
| | 616 | This value must be set. |
| | 617 | |
| | 618 | =item B<Fup2> = I<newsgroup | poster> |
| | 619 | |
| | 620 | A comma-separated list of newsgroup(s) or the special string I<poster> |
| | 621 | as it will appear in the Followup-To header of the message. |
| | 622 | |
| | 623 | This setting is optional. |
| | 624 | |
| | 625 | =item B<MID-Format> = I<pattern> |
| | 626 | |
| | 627 | A pattern from which the message ID is generated as it will appear in |
| | 628 | the Message-ID header of the message. |
| | 629 | |
| | 630 | You may use the special strings C<%n> for the I<Name> of your project, |
| | 631 | C<%d> for the date the message is posted, C<%m> for the month and |
| | 632 | C<%y> for the year, respectively. |
| | 633 | |
| | 634 | This value must be set. |
| | 635 | |
| | 636 | =item B<Supersede> = I<yes> |
| | 637 | |
| | 638 | Add Supersedes header to the message containing the Message-ID header |
| | 639 | of the last posting. |
| | 640 | |
| | 641 | This setting is optional; you should set it to yes or leave it out. |
| | 642 | |
| | 643 | =item B<ExtraHeader> = I<additional headers> |
| | 644 | |
| | 645 | The contents of I<ExtraHeader> is added verbatim to the headers of |
| | 646 | your message so you can add custom headers like Approved. |
| | 647 | |
| | 648 | This setting is optional. |

| | 707 | |
| | 708 | Information about the last post and about how to form message IDs for |
| | 709 | posts is stored in a file named F<I<project name>.cfg> which will be |
| | 710 | generated if it does not exist. Each of those status files will |
| | 711 | contain two lines, the first being the date of the last time the FAQ |
| | 712 | was posted and the second being the message ID of that incarnation. |
| | 713 | |
| | 714 | =head1 OPTIONS |
| | 715 | |
| | 716 | =over 3 |
| | 717 | |
| | 718 | =item B<-V> (version) |
| | 719 | |
| | 720 | Print out version and copyright information on B<yapfaq> and exit. |
| | 721 | |
| | 722 | =item B<-h> (help) |
| | 723 | |
| | 724 | Print this man page and exit. |
| | 725 | |
| | 726 | =item B<-v> (verbose) |
| | 727 | |
| | 728 | Print out status information while running to STDOUT. |
| | 729 | |
| | 730 | =item B<-p> (post unconditionally) |
| | 731 | |
| | 732 | Post (all) FAQs unconditionally ignoring the posting frequency setting. |
| | 733 | |
| | 734 | You may want to use this with the B<-f> option (see below). |
| | 735 | |
| | 736 | =item B<-d> (dry run) |
| | 737 | |
| | 738 | Start B<yapfaq> in simulation mode, i.e. don't post anything and don't |
| | 739 | update any status information. |
| | 740 | |
| | 741 | =item B<-t> I<newsgroup(s) | CONSOLE> (test) |
| | 742 | |
| | 743 | Don't post to the newsgroups defined in F<yqpfaq.cfg>, but to the |
| | 744 | newsgroups given after B<-t> as a comma-separated list or print the |
| | 745 | FAQs to STDOUT separated by lines of dashes if the special string |
| | 746 | C<CONSOLE> is given. This can be used to preview what B<yapfaq> would |
| | 747 | do without embarassing yourself on Usenet. The status files are not |
| | 748 | updated when this option is given. |
| | 749 | |
| | 750 | You may want to use this with the B<-f> option (see below). |
| | 751 | |
| | 752 | =item B<-f> I<project name> |
| | 753 | |
| | 754 | Just deal with one FAQ only. |
| | 755 | |
| | 756 | By default B<yapfaq> will work on all FAQs that are defined in |
| | 757 | F<yapfaq.cfg>, check whether they are due for posting and - if they |
| | 758 | are - post them. Consequently when the B<-p> option is set all FAQs |
| | 759 | will be posted unconditionally. That may not be what you want to |
| | 760 | achieve, so you can limit the operation of B<yapfaq> to the named FAQ |
| | 761 | only. |
| | 762 | |
| | 763 | =back |
| | 764 | |
| | 765 | =head1 EXAMPLES |
| | 766 | |
| | 767 | Post all FAQs that are due for posting: |
| | 768 | |
| | 769 | yapfaq |
| | 770 | |
| | 771 | Do a dry run, showing which FAQs would be posted: |
| | 772 | |
| | 773 | yapfaq -dv |
| | 774 | |
| | 775 | Do a test run and print on STDOUT what the FAQ I<myfaq> would look |
| | 776 | like when posted, regardless whether it is due for posting or not: |
| | 777 | |
| | 778 | yapfaq -pt CONSOLE -f myfaq |
| | 779 | |
| | 780 | Do a "real" test run and post the FAQ I<myfaq> to I<de.test>, but only |
| | 781 | if it is due: |
| | 782 | |
| | 783 | yapfaq -t de.test -f myfaq |
| | 784 | |
| | 785 | =head1 ENVIRONMENT |
| | 786 | |
| | 787 | There are no special environment variables used by B<yapfaq>. |
| | 788 | |
| | 789 | =head1 FILES |
| | 790 | |
| | 791 | =over 4 |
| | 792 | |
| | 793 | =item F<yapfaq.pl> |
| | 794 | |
| | 795 | The script itself. |
| | 796 | |
| | 797 | =item F<yapfaq.cfg> |
| | 798 | |
| | 799 | Configuration file for B<yapfaq>. |
| | 800 | |
| | 801 | =item F<*.cfg> |
| | 802 | |
| | 803 | Status data on FAQs. |
| | 804 | |
| | 805 | The status files will be created on successful posting if they don't |
| | 806 | already exist. The first line of the file will be the date of the last |
| | 807 | time the FAQ was posted and the second line will be the message ID of |
| | 808 | the last post of that FAQ. |
