+
+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>. Everything after a "#"
+sign is ignored so you may comment your configuration file.
+
+=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> (optional)
+
+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>  (optional)
+
+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>  (optional)
+
+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, C<%y>
+for the year and C<%t> for a time stamp (number of seconds since the
+epoch), respectively.
+
+This setting is optional; the default is '<%n-%y-%m-%d@I<YOURHOST>>'
+where I<YOURHOST> is the fully qualified domain name (FQDN) of the
+host B<yapfaq> is running on. Obviously that will only work if you
+have defined a reasonable hostname that the hostfqdn() function of
+Net::Domain can return.
+
+=item B<Charset> = I<encoding>  (optional)
+
+The character encoding of your FAQ. This setting is optional, but
+should match the encoding of your FAQ B<File>. Default is set to
+I<UTF-8>.
+
+This setting is copied verbatim to the I<Content-Type> header.
+
+=item B<Supersede> = I<yes>  (optional)
+
+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>  (optional)
+
+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.
+

+
+=head3 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).

+    # MID-Format = '<%n-%d.%m.%y@domain.invalid>'
+    
+    # Character Encoding
+    # This setting is optional. Default: UTF-8
+    # Charset = ISO-8859-15
+    
+    # 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
+
+=head3 Status Information
+
+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.
+
+=head2 Runtime Configuration
+
+Apart from configuring which FAQ(s) to post you may (re)set some
+runtime configuration variables via the .rcfile (by default
+F<.yapfaqrc>). F<.yapfaqrc> must contain one definition in the form of
+I<param = value> on each line; everything after a "#" sign is ignored.
+
+If you omit some settings they will be set to default values hardcoded
+in F<yapfaq.pl>.
+
+B<Please note that all parameter names are case-sensitive!>
+
+=over 4
+
+=item B<NNTPServer> = I<NNTP server> (mandatory)
+
+Host name of the NNTP server to post to. Must be set (or omitted; the
+default is "localhost"); if set to en empty string, B<yapfaq> falls
+back to Perl's build-in defaults (contents of environment variables
+NNTPSERVER and NEWSHOST; if not set, default from Net::Config; if not
+set, "news" is used).
+
+=item B<NNTPUser> = I<user name> (optional)
+
+User name used for authentication with the NNTP server (I<AUTHINFO
+USER>).
+
+This setting is optional; if it is not set, I<NNTPPass> is ignored and
+no authentication is tried.
+
+=item B<NNTPPass> = I<password> (optional)
+
+Password used for authentication with the NNTP server (I<AUTHINFO
+PASS>).
+
+This setting is optional; it must be set if I<NNTPUser> is present.
+
+=item B<Sender> = I<Sender header> (optional)
+
+The Sender header that will be added to every posted message.
+
+This setting is optional.
+
+=item B<ConfigFile> = I<configuration file> (mandatory)
+
+The configuration file defining the FAQ(s) to post. Must be set (or
+omitted; the default is "yapfaq.cfg").
+
+=item B<Program> = I<file name> (optional)
+
+A program the article is piped to instead of posting it to Usenet.
+See option "-f" below (which takes preference).
+
+This setting is optional.
+
+=back
+
+=head3 Example runtime configuration file
+
+    NNTPServer = 'localhost'
+    NNTPUser   = ''
+    NNTPPass   = ''
+    Sender     = ''
+    ConfigFile = 'yapfaq.cfg'
+    Program    = ''
+
+=head3 Using more than one runtime configuration
+
+You may use more than one runtime configuration file with the B<-c>
+option (see below).
+
+=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
+(test) newsgroup(s) 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.
+
+When this option is used to post to some other newsgroup(s), a(nother)
+timestamp is added to the Message-ID header and the Supersedes header
+is replaced by a special X-Supersedes header.
+
+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.
+
+For example, you may want to use the I<inews> utility from the INN package
+or the much more powerful replacement I<tinews.pl> from
+I<ftp://ftp.tin.org/tin/tools/tinews.pl> which is able to sign postings.
+
+If I<Program> is also defined in the runtime configuration file (by default
+F<.yapfaqrc>), B<-s> takes preference.
+
+=item B<-c> I<.rc file>
+
+Load another runtime configuration file (.rc file) than F<.yaofaq.rc>.
+
+You may for example define another usenet server to post your FAQ(s)
+to or load another configuration file defining (an)other FAQ(s).
+
+=back
+
+=head1 INSTALLATION
+
+Just copy the contents of the tarball in some directory and get started.
+
+You can post your first test with
+
+    yapfaq -c .yapfaqrc.sample
+
+or copy F<.yapfaqrc.sample> to F<.yapfaqrc> and F<yapfaq.cfg.sample>
+to F<yapfaq.cfg>, edit those files and get really started!
+
+=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
+
+Post all FAQs (that are due for posting) using inews from INN:
+
+    yapfaq -s inews
+
+Do a dry run using a runtime configuration from .alternaterc, showing
+which FAQs would be posted:
+
+    yapfaq -dvc .alternaterc
+
+=head1 ENVIRONMENT
+
+=over 4
+
+=item NNTPSERVER
+
+The default NNTP server to post to, used by the Net::NNTP module. You
+can also  specify the server using the runtime configuration file (by
+default F<.yapfaqrc>).
