-=head1 NAME
-
-send-uucp - Send Usenet articles via UUCP
-
-=head1 SYNOPSIS
-
-B<send-uucp> [I<SITE> ...]
-
-=head1 DESCRIPTION
-
-The B<send-uucp> program processes batch files written by innd(8) to send
-Usenet articles to UUCP sites. It reads a configuration file to control how
-it behaves with various sites. Normally, it's run periodically out of cron
-to put together batches and send them to remote UUCP sites.
-
-=head1 OPTIONS
-
-Any arguments provided to the program are interpreted as a list of sites
-specfied in F<send-uucp.cf> for which batches should be generated. If no
-arguments are supplied then batches will be generated for all sites listed
-in that configuration file.
-
-=head1 CONFIGURATION
-
-The sites to which articles are to be sent must be configured in the
-configuration file F<send-uucp.cf>. Each site is specified with a line of
-the form:
-
- site[:host[:funnel]] [compressor [maxsize [batchtime]]]
-
-=over 4
-
-=item I<site>
-
-The news site name being configured. This must match a site name
-from newsfeeds(5).
-
-=item I<host>
-
-The UUCP host name to which batches should be sent for this site.
-If omitted, the news site name will be used as the UUCP host name.
-
-=item I<funnel>
-
-In the case of a site configured as a funnel, B<send-uucp> needs to flush
-the channel (or exploder) being used as the target of the funnel instead of
-flushing the site. This is the way to tell B<send-uucp> the name of the
-channel or exploder to flush for this site. If not specified, default to
-flushing the site.
-
-=item I<compressor>
-
-The compression method to use for batches. This should be one of compress,
-gzip or none. Arguments for the compression command may be specified by
-using C<_> instead of spaces. For example, C<gzip_-9>. The default value is
-C<compress>.
-
-=item I<maxsize>
-
-The maximum size of a single batch before compression. The default value is
-500,000 bytes.
-
-=item I<batchtime>
-
-A comma separated list of hours during which batches should be generated for
-a given site. When B<send-uucp> runs, a site will only be processed if the
-current hour matches one of the hours in I<batchtime>. The default is no
-limitation on when to generate batches.
-
-=back
-
-Fields are seperated by spaces and only the site name needs to be specified,
-with defaults being used for unspecified values. If the first character on
-a line is a C<#> then the rest of the line is ignored.
-
-=head1 EXAMPLE
-
-Here is an example send-uucp.cf configuration file:
-
- zoetermeer gzip 1048576 5,18,22
- hoofddorp gzip 1048576 5,18,22
- pa3ebv gzip 1048576 5,18,22
- drinkel gzip 1048576 5,6,18,20,22,0,2
- manhole compress 1048576 5,18,22
- owl compress 1048576
- able
- pern::MYFUNNEL!
-
-This defines eight UUCP sites. The first four use gzip compression and the
-last three use compress. The first six use a batch size of 1MB, and the
-last site (able) uses the default of 500,000 bytes. The zoetermeer,
-hoofddorp, pa3ebv, and manhole sites will only have batches generated for
-them during the hours of 05:00, 18:00, and 22:00, and the drinkel site will
-only have batches generated during those hours and 20:00, 00:00, and 02:00.
-There are no restrictions on when batches will be generated for owl or able.
-
-The pern site is configured as a funnel into C<MYFUNNEL!>. B<send-uucp> will
-issue C<ctlinnd flush MYFUNNEL!> instead of C<ctlinnd flush pern>.
