X.SH NAME
X$N - gateways incoming mails to news.
X.SH SYNOPSIS
X$N [-f=<sender>] <newsgroup>
X.SH DESCRIPTION
XIn combination with
X.B News_out
X$N can be used to forward news as mails and to allow answering to an
Xarticle via mail. For this you need a flexible mail transport agent,
Xe.g. sendmail or MMail. The
X.B <sender>
Xis optional and currently not used.
X.B <newsgroup>
Xmust be a valid newsgroup either with dots or with hyphens. Valid
Xnewsgroups are then (e.g.) comp-lang-c or rec.games.frp. The hyphen
Xsolution is used to avoid a miss-parsing the dots as domains.
X.SH CAVEATS
XThis is only a very primitiv solution and may cause several problems.

X.SH SYNOPSIS

X [-G=<grade>] [-f=<size>] [-C=<cmd>] [-n=<system>]
X <system>
X.noraw
X.SH DESCRIPTION
X.ti +3
XSbatch collects all article which should be send to a remote system.
XOn default all articles are batched into one file until the size limit
Xis reached. With
X.O -c
Xyou can compress the news to get a better throughput.
X.NO -cf
Xforces `freeze' to be used instead of compresss.
X.NO -c7
Xwill encode them after compression to transmit them over lines which
Xonly supports 7 Bit.
X.NO -cf7
Xwill be used for 7 Bit channels with `freeze' to compress data.
X.NO -s
Xall articles are spooled as single files.
X.NO -f=<size>
Xgives the limit of a file in kBytes. the default is 50 kByte.
X.NO -B=<bitcount>
XTo compress with another bitvalue than 16 (the default, use the option
Xto set the bitvalue to 12 to 16.
X.NO -G=<grade>
XIf your delivering program accepts a grade character in the command
Xstring then you can change this here.
X.NO -C=<cmd>
Xthe delivery command can be changed with this to a complete new value.
XThe command may contain two different sequences for inserting the grade
Xcharacter and the system name. These are
X.bold
X\%S
Xfor the system and
X.bold
X\%G
Xfor the grading.
X.NO -t
Xthis is for use with eight bit characters. If your neighbor host doesn't
Xsupport these characters then they are translated back to pure seven bit
XASCII. Currently only the german umlaute for ISO8859/1 are supported.
X.NO -n=<system>
XIf the name in the command to forward news differs from the filename the
Xbatchfile is stored then this is used as the filename of the batched
Xarticles.
X.EO
X.SH CAVEATS
XThe files are stored in temporary on /dd. If this too small things may
Xfail.
X.SH BUGS
XMay be a lot, none known.
X.SH FILES
X.O /h0/SPOOL/BATCH
XThe articles are stored herein, for each system one file with the
Xfilename of the system. The format is an optional flagfield seperated
Xfrom the main filename by a bar
X.RB (` | ').
XCurrently there are the two flags
X.RB ` N '
Xand
X.RB ` C '
Xfor non-convert and convert from 8 bit (if these optiones are proper
Xinserted the `-t' option is obsolete.)

X.THS Sys 5L News
X.SH NAME
XSys - this file describes the mechanism to forward received articles to
Xother sites or to programs.
X.SH DESCRIPTION
X.ti +3
XThis files specifies the newsgroups and distributions to be forwarded to
Xanother site or to be pipe'd to a program. So you are able to limit the
Xamount of articles to be forwarded by area (distribution) or/and the
Xtopics (newsgroups).
X.SH FORMAT
XThe format of the file is
X.ce
X<system>{> <flags>}:<newsgroups>:<dists>{:<program>}
Xwhere
X.B <system>
Xis in general the system to forward the news (or an ID for programs).
XYou can append a list of other systemnames (seperated by a slash
X.B /
Xform the main system), which are seperated by commas to stop forwarding
Xarticles which had already passed these systems. The
X.B <flags>
Xare a list of flags which are inserted before the filename in the
Xbatchfile. These flags are interpreted by sbatch only. The
X.B <newsgroups>
Xis a list of newsgroups which are in regular expression format (using
XHenry Spencer's regular expression library), seperated by spaces.
XInternal the expression will be enclosed with
X.B ^
Xand
X.bold
X\$
Xto allow only exact matches.
X.B <dists>
Xare the distributions which aren't regular expressions, but they may
Xcontain the meta characters
X.B ?
Xand
X.B *
Xto match one (?) or zero or more (*) characters. The <newsgroups> and
X<dists> field allow a not operation by prefixing an expression with an
X.B !
Xso you can select specific items not to be forwarded. If an article
Xshould be forwarded the filename is written in a file in
X.B /h0/SPOOL/BATCH
Xwith the filename equal to <system> (if possible). This file is used by
X.B sbatch
Xto send the articles themselves.
X.PP
XThe
X.B <program>
Xis optional but if it is given the filename of the article isn't written
Xto the file mentioned above but the article itself is pipe'd to this
Xprogram (so the program must read the article from stdin).
X.PP
XIf the first character of <program> is a plus sign then the rest will be
Xused as a full path to a directory where to store the articles with
Xincreasing numbers. If the first character is a minus sign then the rest
Xis a full path to a directory which is used instead of the batch
Xdirectory (/h0/SPOOL/BATCH).
X.PP
XEach line in this file may be continued in the next line if the last
Xcharacter in the prvious line had been a backslash.
X.PP
XIf a line starts with a colon
X.RB ( : )
Xthen the rest of the line is taken as a filename of a file to be
Xincluded. With this features it is possible to create one file for each
Xsystem which can be changed from remote via mail. For this purpose the
Xprogram
X.B remsys
Xcan be found in this distribution.
X.SH EXAMPLES
X.raw 4
Xmyfeed:!local.* to\\.myfeed !to\\..* .*:!local *
Xsubfeed:(sub|muc)\\..*:sub muc world
Xsave:.*source.*:*:save_it
X.noraw
X.B myfeed
Xwill get everything expect these newsgroups which are prefixed by
X.B local
Xor have distribution
X.B local
Xor have the prefix
X.B to.
Xand not followed by myfeed.
X.B subfeed
Xwill only receive groups of a local are (Newsgroups prefixed by muc. or
Xsub. and distribution muc sub and world). The entry
X.B save
Xwill store (assuming a proper program) all articles in source groups.

X * Encoding uses acsii chars from ' ' .. 'z'

X * Method is to expand 3 chars -> 4 6 bit ones.

X * 13 bits (max value 8191) can be represented as
X * A * 91 + B
X * where A < 91, B < 91 (91^2 == 8281, so it fits!)
X *
X * Each of A and B is encoded as a character by adding 32

X *
X * The termination conditions are foul beyond belief. Don't
X * monkey with them!
X *
X * If you think its a fluke that 040 .. 0171 just happen to
X * be the chars that Piet Beertema's uucp 'f' protocol transmits
X * as single bytes, you're insane. 0172 chars are produced
X * with lower frequency than any other (given random data)
X * so the doubling that occurs with that we will just suffer.
