Turn is a multi-threaded, threading newsreader. (That is, it has multiple light-weight processes, and it groups articles together in trees based on the References line) with some very special features.
alt.binariesnewsgroups can be displayed with a single keystroke.
inst,swmgr} -f foo"appearing in article text are automatically highlighted. A single click brings up the SoftwareManager to install that distribution.
One of the main goals of turn is to make the user wait as little as possible for the newsreader.
For much more information about turn you can consult turn's on-line documentation at http://reality.sgi.com/turn.

This section lists the subsystems (and their sizes in 1024-byte blocks) of turn.
If you are installing this product for the first time, the subsystems marked ``default'' are the ones that are installed if you use the ``go'' menu item. To install a different set of subsystems, use the ``install,'' ``remove,'' ``keep,'' and ``step'' commands in inst to customize the list of subsystems to be installed, then select the ``go'' menu item.
Note: The listed subsystem sizes are approximate. Refer to the Software Installation Administrator's Guide for information on finding exact sizes.

All of the subsystems for turn can be installed using IRIX. You do not need to use the miniroot. If you are installing from the Freeware 1.0 CD, refer to the Software Installation Administrator's Guide for complete installation instructions.
The synopsis is:
su swmgr -f <foo>/fw_turn (Type "go" at the "inst>" prompt.) exit
Replace <foo> with the location of the turn distribution on your network or CD. You can use inst instead of
swmgr if you prefer command line programs.
If you do not have the Freeware 1.0 CD or the turn software distribution pick one of the following:
The turn.sw.pict and turn.man.pict subsystems have prerequisites to ensure you have all the necessary picture, sound and movie viewers installed. The prerequisites are:
The turn.man.relnotes subsystem has the following prerequisite:
The products prefixed with fw_ are all on the freeware CD or contained within the turn distribution. The remaining products are standard parts of the IRIX distribution. The dmedia tools must be at least those from Desktop-Special-Edition 1.0. This is version 5.5 of the dmedia tools.
Mmail is needed for the program metamail which is used to decode MIME encoded messages posted as articles.
System Software Requirements: IRIX 5.3 with Desktop Special Edition or IRIX 6.2
All configuration files are in /usr/freeware/lib/turn.
Turn, like everything on the Freeware 1.0 CD installs under /usr/freeware. For normal operation you must add the following elements to your search paths.
If this is version 1.0 why are there any changes and additions? Turn has been in use inside Silicon Graphics for a number of years. This section is to inform our loyal users what has changed since the last internal release of turn.
If this is version 1.0 why are there any bug fixes to report? Turn has been in use inside Silicon Graphics for a number of years. This section is to inform the loyal users what has been fixed since the last internal release of turn.
-qoption which suppresses its usual noisy output. In spite of this you may still see the following annoying message appear in a pop-up:
NOTE: TO MAKE THE PICTURE WINDOW GO AWAY, JUST TYPE q IN IT. ==> TO SAVE THIS IMAGE, COPY THE FILE /tmp/mm.a001UX BEFORE EXITING
This message comes from a script called showpicture. The most recent version of
/etc/mailcap only uses showpicture to display x-xwd (i..e x screen dump) format images. Earlier versions used showpicture for all images. If you see this message often, you most likely have an old
/etc/mailcap. You can either create you own
~/.mailcap file to override the system's or install the latest version of MediaMail,
which contains the default
/etc/mailcap. The latest MediaMail is distributed as part of Silicon Graphics' MindShare
software. Here's a suggested
~/.mailcap file, if you wish to create you own:
# Override some of the defaults in the system mailcap image/x-sgi-image; ipaste -f %s; compose=imgworks %s; \ description="SGI image"; \ x11-bitmap="/usr/lib/Zmail/bitmaps/image.xbm" image/x-bitmap; bitmap %s; description="X11 bitmap"; \ x11-bitmap="/usr/lib/Zmail/bitmaps/bitmap.xbm" image/x-xpm1; olpixmap %s; description="OL pixmap"; \ x11-bitmap="/usr/lib/Zmail/bitmaps/bitmap.xbm" image/tiff; tiffgt -f %s; compose=imgworks %s; \ description="TIFF image"; \ x11-bitmap="/usr/lib/Zmail/bitmaps/image.xbm" image/gif; igif -f %s; compose=imgworks %s; \ description="GIF image"; \ x11-bitmap="/usr/lib/Zmail/bitmaps/image.xbm" image/jpeg; jpaste -f %s; compose=imgworks %s; \ description="JFIF image"; \ x11-bitmap="/usr/lib/Zmail/bitmaps/image.xbm" image/jpg; jpaste -f %s; compose=imgworks %s; \ description="JFIF image"; \ x11-bitmap="/usr/lib/Zmail/bitmaps/image.xbm" image/x-xwd; showpicture %s; \ description="An X11 window image dump in X-XWD format" application/x-showcase; showcase -f %s; compose=showcase -f %s; \ description="Showcase document"; \ x11-bitmap="/usr/lib/Zmail/bitmaps/showcase.xbm"
At startup turn has to obtain the list of newsgroups and the threads overview for each newsgroup from the NNTP server. Given the large number of newsgroups, a lot of data must be transferred. Turn caches the overviews from your last session to minimize the amount of data transferred. Nevertheless obtaining the information takes a considerable amount of time during which the Updating Threads lamp on the menu bar will be lit.
During this phase you can use turn normally as lines appear in the newsgroup list. However there will be many short periods uring which turn does not pay attention to the user and displays a watch cursor. Normally one of these periods lasts for only 1 or 2 seconds. It could last longer if interruptions occur in the network connection to your NNTP server. If you pop up a menu just before one of these periods, your system will appear frozen until turn once again pays attention to the user and handles the menu events. This is because turn grabs the X server while a menu is popped, an unavoidable necessity with the X Window System.
If a lengthy network interruption occurs at one of these times when you
have a turn menu popped, and your need to unfreeze your system, rlogin from another
