+
+ yapfaq - Post Usenet FAQs I<(yet another postfaq)>
+
+ =head1 SYNOPSIS
+
+ B<yapfaq> [B<-hvpd>] [B<-t> I<newsgroups> | CONSOLE] [B<-f> I<project name>]
+
+ =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>.
+
+ =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>
+
+ 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>
+
+ 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>
+
+ 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 and
+ C<%y> for the year, respectively.
+
+ This value must be set.
+
+ =item B<Supersede> = I<yes>
+
+ 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>
+
+ 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
+
+ =head2 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>'
+
+ # 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
+
+ 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.
+
+ =head1 OPTIONS
+
+ =over 3
+
+ =item B<-h> (help)
+
+ Print out version and usage information on B<yapfaq> 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
+ newsgroups 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.
+
+ 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.
+
+ =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
+
+ =head1 ENVIRONMENT
+
+ There are no special environment variables used by B<yapfaq>.
+
+ =head1 FILES
+
+ =over 4
+
+ =item F<yapfaq.pl>
+
+ The script itself.
+
+ =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.
+
+ =back
+
+ =head1 BUGS
+
+ Many, I'm sure.
+
+ =head1 SEE ALSO
