X#
X# LIBS:
X# should point to any extra libraries needed, such as termcap. You

X# systems, you may want to put that here
X#
X# EXTRAOBJS:
X# may be used to include tmpnam.s, strtok.s, reg.s in the list.
X#
X# These objects implement SYSV utilities for BSD machines.
X#
X# strtok.s implements strtok() / strpbrk(). reg.s implements regex()/regcmp()
X# on top of the BSD regular expression library (regex() allows multiple
X# regular expressions). tmpnam.s implements tmpnam() of course.
X#
X# If you have them, use your own regex/regcmp, because:
X#
X# i) They should be faster than the reg.c code, which
X# recompiles the "current" ucb string every time you
X# switch regular expressions.
X#
X# ii) I briefly checked out reg.c once, and it seemed to
X# work. Our system has the "real" calls available, so I
X# run with those. reg.c hasn't been used much by me, although
X# I've had nobody tell me it doesn't work.
X#
X# if you DON'T include reg.s, be sure you set -Dregfree=free in CFLAGS.
X#
X# As with regex, if you have a system strtok(), it is likely more efficient -
X# string routines will often be done in assembler on a given machine.
X#
X# Even if you have it, you can use tmpnam.s anyhow. This version will tailor
X# the temp file name to vnXXXXXX, instead of a generic tmpXXXXXX.

X
XIntroduction
X============
X
Xvn is a newsreader, similar to rn, vnews or nn and comes with full
Xsource (executable was created with DICE V2.05). All that is required
Xto run it is access to usenet messages (on a floppy from a friend is
Xhow I get usenet!).
X
XUpdates from Release 1 is the use of the AmigaUUCP Config file for most
Xoptions such as News directory, location and name of the .newsrc and
Xactive files. Also the user can set whether to use nested directories or
Xdirectories the same as the newsgroup name e.g.
XUUNEWS:comp/sys/amiga/misc or UUNEWS:comp.sys.amiga.misc.

XRELEASE NOTES FOR AMIGA VN (res1.1 8/88) 14/Nov/1990
X====================================================
X
X
X
XIntroduction
X============
X
Xvn is a newsreader, similar to rn, vnews or nn. It requires less memory
Xthan Arn 0.67 (Arn failed to run on my 1 meg amiga due to lack of
Xmemory) and comes with full source (executable was created with DICE
XV2.02). All that is required to run it is access to usenet messages (on
Xa floppy from a friend is how I get usenet!).
X
XSetting Up vn on the amiga
X==========================
X
X1. assign NEWS: <base directory of newsgrups>
X2. create a file called "active" in the directory NEWS: which contains
X the name of each news group you are interested in followed by the
X last message in the group
X e.g.
X comp.sys.amiga 30221
X comp.sys.amiga.games 2011
X3. do the following SETENVs and copy
X SETENV term amiga-p (or amiga-n if using an NTSC machine)
X SETENV PALAMIGA Y (or N if using an NTSC machine)
X copy termcap s:
X
X4. (optional) create a file called s:.newsrc containing information
X about the news groups you wish to read. If you don't create this file
X then vn will create it for you. (be prepared for a long wait while vn
X tries each file from 1 to the last message (as specified in the
X news:active file) for each newsgroup you specified in the news:active
X file).
X FILE FORMAT:
X groupname: <first message> <last message read>
X e.g.
X comp.sys.amiga: 1-30119
X comp.sys.amiga.games: 1-1998
X5. set the stack (I know 20000 works) if it is not already set to some
X large value on your system. If the stack is not set large enough then
X vn will crash probably resulting in a !GURU!
X e.q. stack 20000
X6. type "vn" at the prompt.
X
XNotes on the directory structure required.
X==========================================
X
XIf the group name is comp.sys.amiga then the news files will reside in a
Xdirectory called "NEWS:comp/sys/amiga". All the news files will have numeric
Xnames such as "30221" which correspond to the entries in the .newsrc and
Xactive files.
X
XAdditional Notes:
X=================
X
XSome of the internal commands require that the following programs or devices
Xare available, either mounted or in your command path:
X
Xprint (a print spooler command)
Xnull: (a device handler)
X
XAdditionally all the commands for replying to news etc still are the MINIX
Xor SYSV equivalents as I do not have access to a UUCP node (I don't even
Xown a modem).
X
XBUGS.
X=====
X
XThere are none in the parts I have tested. I have not tried the
Xreply/sendmail parts and have not changed the source code for the
Xamiga. It should be a simple matter to adapt the source for these
Xfunctions.
X
X
XADVANTAGES OF vn OVER rn.
X=========================
X
Xvn presents you with a list of articles and allows you to select which ones
Xto read based on the subject and from lines. This allows you to quickly
Xpass over news threads that are not of interest to you. Of course nn does
Xthis and also organised the news in threads whereas vn presents the news
Xin chronological order (this means that sometimes the original message
Xappears after a reply - due to the order/direction the news filters through
Xto your site). This is a vast improvement over the way rn and vnews allow you
Xto read news. (NOTE: I do not know how Arn works as I could not run it on my
X1meg A500).
