-
-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).

-    
-    # Supersede last posting?
-    Supersede = yes
-    
-    # extra headers (appended verbatim)

-    
-    # other projects may follow separated with "====="
-    =====
-    
-    Name = 'othertest'

-    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>).

-
-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
