+B<yapfaq> [B<-hvpd>] [B<-t> I<newsgroups> | CONSOLE] [B<-f> I<project name>] [B<-s> I<program>]
+
+=head1 REQUIREMENTS

+Perl 5.8 or later

+=item -
+
+Net::NNTP

+
+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<-V> (version)
+
+Print out version and copyright information on B<yapfaq> and exit.
+
+=item B<-h> (help)
+
+Print this man page 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.
+
+=item B<-s> I<program> (pipe to script)
+
+Instead of posting the article(s) to Usenet pipe them to the external
+I<program> on STDIN (which may post the article(s) then). A return
+value of 0 will be considered success.
+
+=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.
