+
+
+* Changes in Oort Gnus
+
+** `F' (`gnus-article-followup-with-original') and `R'
+(`gnus-article-reply-with-original') only yank the text in the region if the
+region is active.
+
+** `gnus-group-read-ephemeral-group' can be called interactively, using `G M'.
+
+** In draft groups, `e' is now bound to `gnus-draft-edit-message'.
+Use `B w' for `gnus-summary-edit-article' instead.
+
+** The revised Gnus FAQ is included in the manual.
+See the info node "Frequently Asked Questions".
+
+** Upgrading from previous (stable) version if you have used Oort.
+
+If you have tried Oort (the unstable Gnus branch leading to this
+release) but went back to a stable version, be careful when upgrading
+to this version.  In particular, you will probably want to remove all
+.marks (nnml) and .mrk (nnfolder) files, so that flags are read from
+your ~/.newsrc.eld instead of from the .marks/.mrk file where this
+release store flags.  See a later entry for more information about
+marks.  Note that downgrading isn't safe in general.
+
+** Article Buttons
+
+More buttons for URLs, mail addresses, Message-IDs, Info links, man pages and
+Emacs or Gnus related references, see the info node "Article Buttons".  The
+variables `gnus-button-*-level' can be used to control the appearance of all
+article buttons, see the info node "Article Button Levels".
+
+** Dired integration
+
+`gnus-dired-minor-mode' installs key bindings in dired buffers to send a file
+as an attachment (`C-c C-m C-a'), open a file using the approriate mailcap
+entry (`C-c C-m C-l'), and print a file using the mailcap entry (`C-c C-m
+C-p').  See the info node "Other modes".
+
+
+** Gnus can display RSS newsfeeds as a newsgroup.  To get started do `B
+nnrss RET RET' in the Group buffer.
+
+** Single-part yenc encoded attachments can be decoded.
+
+** Picons
+The picons code has been reimplemented to work in Emacs 21 -- some of
+the previous options have been removed or renamed.
+
+Picons are small "personal icons" representing users, domain and
+newsgroups, which can be displayed in the Article buffer.  To enable
+picons, install the picons database from
+
+      http://www.cs.indiana.edu/picons/ftp/index.html
+
+and point `gnus-picon-databases' to that location.
+
+** If the new option `gnus-treat-body-boundary' is `head', a boundary 
+line is drawn at the end of the headers.
+
+** Retrieval of charters and control messages
+There are new commands for fetching newsgroup charters (`H c') and
+control messages (`H C').
+
+** Delayed articles
+You can delay the sending of a message with `C-c C-j' in the Message
+buffer.  The messages are delivered at specified time.  This is useful
+for sending yourself reminders.  Setup with (gnus-delay-initialize).
+
+** If `auto-compression-mode' is enabled, attachments are automatically
+decompressed when activated.
+
+** If the new option `nnml-use-compressed-files' is non-nil, 
+the nnml back end allows compressed message files.
+
+** Signed article headers (X-PGP-Sig) can be verified with `W p'.
+
+** The Summary Buffer uses an arrow in the fringe to indicate the
+current article in Emacs 21 running on a graphical display.  Customize
+`gnus-summary-display-arrow' to disable it.
+
+** Warn about email replies to news
+Do you often find yourself replying to news by email by mistake?  Then
+the new option `gnus-confirm-mail-reply-to-news' is just the thing for
+you.
+
+** If the new option `gnus-summary-display-while-building' is non-nil, 
+the summary buffer is shown and updated as it's being built.
+
+** The new `recent' mark "." indicates newly arrived messages (as
+opposed to old but unread messages).
+
+** The new option `gnus-gcc-mark-as-read' automatically marks 
+Gcc articles as read.
+
+** The nndoc back end now supports mailman digests and exim bounces.
+
+** Gnus supports RFC 2369 mailing list headers, and adds a number of 
+related commands in mailing list groups.
+
+** The Date header can be displayed in a format that can be read aloud
+in English, see `gnus-treat-date-english'.
+
+** The envelope sender address can be customized when using Sendmail, see 
+`message-sendmail-envelope-from'.
+
+** diffs are automatically highlighted in groups matching
+`mm-uu-diff-groups-regexp'
+
+** TLS wrapper shipped with Gnus
+
+TLS/SSL is now supported in IMAP and NNTP via tls.el and GNUTLS.  The
+old TLS/SSL support via (external third party) ssl.el and OpenSSL
+still works.
+
+** New make.bat for compiling and installing Gnus under MS Windows
+
+Use make.bat if you want to install Gnus under MS Windows, the first
+argument to the batch-program should be the directory where xemacs.exe
+respectively emacs.exe is located, iff you want to install Gnus after
+compiling it, give make.bat /copy as the second parameter.
+
+`make.bat' has been rewritten from scratch, it now features automatic
+recognition of XEmacs and GNU Emacs, generates gnus-load.el, checks if
+errors occur while compilation and generation of info files and reports
+them at the end of the build process.  It now uses makeinfo if it is
+available and falls back to infohack.el otherwise.  `make.bat' should now
+install all files which are necessary to run Gnus and be generally a
+complete replacement for the "configure; make; make install" cycle used
+under Unix systems.
+
+The new make.bat makes make-x.bat superfluous, so it has been removed.
+
+** Support for non-ASCII domain names
+
+Message supports non-ASCII domain names in From:, To: and Cc: and will
+query you whether to perform encoding when you try to send a message.
+The variable `message-use-idna' controls this.  Gnus will also decode
+non-ASCII domain names in From:, To: and Cc: when you view a message.
+The variable `gnus-use-idna' controls this.
+
+** Better handling of Microsoft citation styles
+
+Gnus now tries to recognize the mangled header block that some Microsoft
+mailers use to indicate that the rest of the message is a citation, even
+though it is not quoted in any way.  The variable
+`gnus-cite-unsightly-citation-regexp' matches the start of these
+citations.
+
+** gnus-article-skip-boring
+
+If you set `gnus-article-skip-boring' to t, then Gnus will not scroll
+down to show you a page that contains only boring text, which by
+default means cited text and signature.  You can customize what is
+skippable using `gnus-article-boring-faces'.
+
+This feature is especially useful if you read many articles that
+consist of a little new content at the top with a long, untrimmed
+message cited below.
+
+** The format spec %C for positioning point has changed to %*.
+
+** The new variable `gnus-parameters' can be used to set group parameters.
+
+Earlier this was done only via `G p' (or `G c'), which stored the
+parameters in ~/.newsrc.eld, but via this variable you can enjoy the
+powers of customize, and simplified backups since you set the variable
+in ~/.emacs instead of ~/.newsrc.eld.  The variable maps regular
+expressions matching group names to group parameters, a'la:
+
+     (setq gnus-parameters
+           '(("mail\\..*"
+              (gnus-show-threads nil)
+              (gnus-use-scoring nil))
+             ("^nnimap:\\(foo.bar\\)$"
+              (to-group . "\\1"))))
+
+** Smileys (":-)", ";-)" etc) are now iconized for Emacs too.
+
+Customize `gnus-treat-display-smileys' to disable it.
+
+** Gnus no longer generates the Sender: header automatically.
+
+Earlier it was generated iff the user configurable email address was
+different from the Gnus guessed default user address.  As the guessing
+algorithm is rarely correct these days, and (more controversially) the
+only use of the Sender: header was to check if you are entitled to
+cancel/supersede news (which is now solved by Cancel Locks instead,
+see another entry), generation of the header has been disabled by
+default.  See the variables `message-required-headers',
+`message-required-news-headers', and `message-required-mail-headers'.
+
+** Features from third party message-utils.el added to message.el.
+
+Message now asks if you wish to remove "(was: <old subject>)" from
+subject lines (see `message-subject-trailing-was-query').  C-c M-m and
+C-c M-f inserts markers indicating included text.  C-c C-f a adds a
+X-No-Archive: header.  C-c C-f x inserts appropriate headers and a
+note in the body for cross-postings and followups (see the variables
+`message-cross-post-*').
+
+** References and X-Draft-Headers are no longer generated when you
+start composing messages and `message-generate-headers-first' is nil.
+
+** Improved anti-spam features.
+
+Gnus is now able to take out spam from your mail and news streams
+using a wide variety of programs and filter rules.  Among the supported
+methods are RBL blocklists, bogofilter and white/blacklists.  Hooks
+for easy use of external packages such as SpamAssassin and Hashcash
+are also new.
+
+** Easy inclusion of X-Faces headers.
+
+** In the summary buffer, the new command / N inserts new messages and
+/ o inserts old messages.
+
+** Gnus decodes morse encoded messages if you press W m.
+
+** Unread count correct in nnimap groups.
+
+The estimated number of unread articles in the group buffer should now
+be correct for nnimap groups.  This is achieved by calling
+`nnimap-fixup-unread-after-getting-new-news' from the
+`gnus-setup-news-hook' (called on startup) and
+`gnus-after-getting-new-news-hook' (called after getting new mail).
+If you have modified those variables from the default, you may want to
+add n-f-u-a-g-n-n again.  If you were happy with the estimate and want
+to save some (minimal) time when getting new mail, remove the
+function.
+
+** Group Carbon Copy (GCC) quoting
+
+To support groups that contains SPC and other weird characters, groups
+are quoted before they are placed in the Gcc: header.  This means
+variables such as `gnus-message-archive-group' should no longer
+contain quote characters to make groups containing SPC work.  Also, if
+you are using the string "nnml:foo, nnml:bar" (indicating Gcc into two
+groups) you must change it to return the list ("nnml:foo" "nnml:bar"),
+otherwise the Gcc: line will be quoted incorrectly.  Note that
+returning the string "nnml:foo, nnml:bar" was incorrect earlier, it
+just didn't generate any problems since it was inserted directly.
+
+** ~/News/overview/ not used.
+
+As a result of the following change, the ~/News/overview/ directory is
+not used any more.  You can safely delete the entire hierarchy.
+
+** gnus-agent
+
+The Gnus Agent has seen a major update.  It is now enabled by default,
+and all nntp and nnimap servers from `gnus-select-method' and
+`gnus-secondary-select-method' are agentized by default.  Earlier only
+the server in `gnus-select-method' was agentized by the default, and the
+agent was disabled by default.  When the agent is enabled, headers are
+now also retrieved from the Agent cache instead of the backends when
+possible.  Earlier this only happened in the unplugged state.  You can
+enroll or remove servers with `J a' and `J r' in the server buffer.
+Gnus will not download articles into the Agent cache, unless you
+instruct it to do so, though, by using `J u' or `J s' from the Group
+buffer.  You revert to the old behaviour of having the Agent disabled
+by customizing `gnus-agent'.  Note that putting `(gnus-agentize)' in
+~/.gnus is not needed any more.
+
+** gnus-summary-line-format
+
+The default value changed to "%U%R%z%I%(%[%4L: %-23,23f%]%) %s\n".
+Moreover `gnus-extra-headers', `nnmail-extra-headers' and
+`gnus-ignored-from-addresses' changed their default so that the users
+name will be replaced by the recipient's name or the group name
+posting to for NNTP groups.
+
+** deuglify.el (gnus-article-outlook-deuglify-article)
+
+A new file from Raymond Scholz <rscholz@zonix.de> for deuglifying
+broken Outlook (Express) articles.
+
+** (require 'gnus-load)
+
+If you use a stand-alone Gnus distribution, you'd better add
+"(require 'gnus-load)" to your ~/.emacs after adding the Gnus
+lisp directory into load-path.
+
+File gnus-load.el contains autoload commands, functions and variables,
+some of which may not be included in distributions of Emacsen.
+
+** gnus-slave-unplugged
+
+A new command which starts gnus offline in slave mode.
+
+** message-insinuate-rmail
+
+Adding (message-insinuate-rmail) in .emacs and customizing
+`mail-user-agent' to `gnus-user-agent' convinces Rmail to compose,
+reply and forward messages in Message mode, where you can enjoy the
+power of MML.
+
+** message-minibuffer-local-map
+
+The line below enables BBDB in resending a message:
+
+(define-key message-minibuffer-local-map [?\t] 'bbdb-complete-name)
+
+** Externalizing and deleting of attachments.
+
+If `gnus-gcc-externalize-attachments' (or
+`message-fcc-externalize-attachments') is non-nil, attach local files
+as external parts.
+
+The command `gnus-mime-save-part-and-strip' (bound to `C-o' on MIME
+buttons) saves a part and replaces the part with an external one.
+`gnus-mime-delete-part' (bound to `d' on MIME buttons) removes a part.
+It works only on back ends that support editing.
+
+** gnus-default-charset
+
+The default value now guesses on the basis of your environment instead
+of using Latin-1.  Also the ".*" item in gnus-group-charset-alist is
+removed.
+
+** gnus-posting-styles
+
+Add a new format of match like
+
+        ((header "to" "larsi.*org")
+         (Organization "Somewhere, Inc."))
+
+The old format like the lines below is obsolete, but still accepted.
+
+        (header "to" "larsi.*org"
+         (Organization "Somewhere, Inc."))
+
+** message-ignored-news-headers and message-ignored-mail-headers
+
+X-Draft-From and X-Gnus-Agent-Meta-Information have been added into
+these two variables.  If you customized those, perhaps you need add
+those two headers too.
+
+** Gnus reads the NOV and articles in the Agent if plugged.
+
+If one reads an article while plugged, and the article already exists
+in the Agent, it won't get downloaded once more.  Customize
+`gnus-agent-cache' to revert to the old behavior.
+
+** Gnus supports the "format=flowed" (RFC 2646) parameter.
+
+On composing messages, it is enabled by `use-hard-newlines'.  Decoding
+format=flowed was present but not documented in earlier versions.
+
+** Gnus supports the generation of RFC 2298 Disposition Notification requests.
+
+This is invoked with the C-c M-n key binding from message mode.
+
+** Gnus supports Maildir groups.
+
+Gnus includes a new backend nnmaildir.el.
+
+** Printing capabilities are enhanced.
+
+Gnus supports Muttprint natively with O P from the Summary and Article
+buffers.  Also, each individual MIME part can be printed using p on
+the MIME button.
+
+** Message supports the Importance: (RFC 2156) header.
+
+In the message buffer, `C-c C-f C-i' or `C-c C-u' cycles through the
+valid values.
+
+** Gnus supports Cancel Locks in News.
+
+This means a header "Cancel-Lock" is inserted in news posting.  It is
+used to determine if you wrote a article or not (for cancelling and
+superseding).  Gnus generates a random password string the first time
+you post a message, and saves it using the Custom system.  While the
+variable is called `canlock-password', it is not security sensitive
+data.  Publishing your canlock string on the web will not allow anyone
+to be able to anything she could not already do.  The behaviour can be
+changed by customizing `message-insert-canlock'.
+
+** Gnus supports server-side mail filtering using Sieve.
+
+Sieve rules can be added as Group Parameters for groups, and the
+complete Sieve script is generated using `D g' from the Group buffer,
+and then uploaded to the server using `C-c C-l' in the generated Sieve
+buffer.  Search the online Gnus manual for "sieve", and see the new
+Sieve manual, for more information.
+
+** Extended format specs.
+
+Format spec "%&user-date;" is added into
+`gnus-summary-line-format-alist'.  Also, user defined extended format
+specs are supported.  The extended format specs look like "%u&foo;",
+which invokes function `gnus-user-format-function-foo'.  Because "&" is
+used as the escape character, old user defined format "%u&" is no
+longer supported.
+
+** `/ *' (gnus-summary-limit-include-cached) is rewritten.
+
+It was aliased to `Y c' (gnus-summary-insert-cached-articles). The new
+function filters out other articles.
+
+** Some limiting commands accept a C-u prefix to negate the match.
+
+If C-u is used on subject, author or extra headers, i.e., `/ s', `/
+a', and `/ x' (gnus-summary-limit-to-{subject,author,extra})
+respectively, the result will be to display all articles that do not
+match the expression.
+
+** Group names are treated as UTF-8 by default.
+
+This is supposedly what USEFOR wanted to migrate to.  See
+`gnus-group-name-charset-group-alist' and
+`gnus-group-name-charset-method-alist' for customization.
+
+** The nnml and nnfolder backends store marks for each group.
+
+This makes it possible to take backup of nnml/nnfolder servers/groups
+separately of ~/.newsrc.eld, while preserving marks.  It also makes it
+possible to share articles and marks between users (without sharing
+the ~/.newsrc.eld file) within e.g. a department.  It works by storing
+the marks stored in ~/.newsrc.eld in a per-group file ".marks" (for
+nnml) and "groupname.mrk" (for nnfolder, named "groupname").  If the
+nnml/nnfolder is moved to another machine, Gnus will automatically use
+the .marks or .mrk file instead of the information in ~/.newsrc.eld.
+The new server variables `nnml-marks-is-evil' and
+`nnfolder-marks-is-evil' can be used to disable this feature.
+
+** The menu bar item (in Group and Summary buffer) named "Misc" has
+been renamed to "Gnus".
+
+** The menu bar item (in Message mode) named "MML" has been renamed to
+"Attachments".  Note that this menu also contains security related
+stuff, like signing and encryption.
+
+** gnus-group-charset-alist and gnus-group-ignored-charsets-alist.
+
+The regexps in these variables are compared with full group names
+instead of real group names in 5.8.  Users who customize these
+variables should change those regexps accordingly. For example:
+
+   ("^han\\>" euc-kr) -> ("\\(^\\|:\\)han\\>" euc-kr)
+
+** Gnus supports PGP (RFC 1991/2440), PGP/MIME (RFC 2015/3156) and
+S/MIME (RFC 2630-2633).
+
+It needs an external S/MIME and OpenPGP implementation, but no
+additional lisp libraries.  This add several menu items to the
+Attachments menu, and C-c RET key bindings, when composing messages.
+This also obsoletes `gnus-article-hide-pgp-hook'.
+
+** Gnus inlines external parts (message/external).
+
+** MML (Mime compose) prefix changed from `M-m' to `C-c C-m'.
+
+This change was made to avoid conflict with the standard binding of
+`back-to-indentation', which is also useful in message mode.
+
+** The default for message-forward-show-mml changed to symbol best.
+
+The behaviour for the `best' value is to show MML (i.e., convert MIME
+to MML) when appropriate.  MML will not be used when forwarding signed
+or encrypted messages, as the conversion invalidate the digital
+signature.
+
+** Bug fixes.
+
+
+* Changes in Pterodactyl Gnus (5.8/5.9)
+
+The Gnus NEWS entries are short, but they reflect sweeping changes in
+four areas: Article display treatment, MIME treatment,
+internationalization and mail-fetching.
+
+** The mail-fetching functions have changed.  See the manual for the
+many details.  In particular, all procmail fetching variables are gone.
+
+If you used procmail like in
+
+(setq nnmail-use-procmail t)
+(setq nnmail-spool-file 'procmail)
+(setq nnmail-procmail-directory "~/mail/incoming/")
+(setq nnmail-procmail-suffix "\\.in")
+
+this now has changed to 
+
+(setq mail-sources
+      '((directory :path "~/mail/incoming/"
+                   :suffix ".in")))
+
+More information is available in the info doc at Select Methods ->
+Getting Mail -> Mail Sources
+
+** Gnus is now a MIME-capable reader.  This affects many parts of
+Gnus, and adds a slew of new commands.  See the manual for details.
+
+** Gnus has also been multilingualized.  This also affects too
+many parts of Gnus to summarize here, and adds many new variables.
+
+** gnus-auto-select-first can now be a function to be
+called to position point.
+
+** The user can now decide which extra headers should be included in
+summary buffers and NOV files.
+
+** `gnus-article-display-hook' has been removed.  Instead, a number
+of variables starting with `gnus-treat-' have been added.
+
+** The Gnus posting styles have been redone again and now works in a
+subtly different manner.
+
+** New web-based backends have been added: nnslashdot, nnwarchive
+and nnultimate.  nnweb has been revamped, again, to keep up with
+ever-changing layouts.
+
+** Gnus can now read IMAP mail via nnimap.

-** SCO Unix and UnixWare
-
-*** SCO 3.2v4: Unusable default font.
-
-The Open Desktop environment comes with default X resource settings
-that tell Emacs to use a variable-width font.  Emacs cannot use such
-fonts, so it does not work.
-
-This is caused by the file /usr/lib/X11/app-defaults/ScoTerm, which is
-the application-specific resource file for the `scoterm' terminal
-emulator program.  It contains several extremely general X resources
-that affect other programs besides `scoterm'.  In particular, these
-resources affect Emacs also:
-
-        *Font: -*-helvetica-medium-r-*--12-*-p-*
-        *Background:                    scoBackground
-        *Foreground:                    scoForeground
-
-The best solution is to create an application-specific resource file for
-Emacs, /usr/lib/X11/sco/startup/Emacs, with the following contents:
-
-        Emacs*Font:     -*-courier-medium-r-*-*-*-120-*-*-*-*-iso8859-1
-        Emacs*Background:       white
-        Emacs*Foreground:       black
-
-(These settings mimic the Emacs defaults, but you can change them to
-suit your needs.)  This resource file is only read when the X server
-starts up, so you should restart it by logging out of the Open Desktop
-environment or by running `scologin stop; scologin start` from the shell
-as root.  Alternatively, you can put these settings in the
-/usr/lib/X11/app-defaults/Emacs resource file and simply restart Emacs,
-but then they will not affect remote invocations of Emacs that use the
-Open Desktop display.
-
-These resource files are not normally shared across a network of SCO
-machines; you must create the file on each machine individually.
-
-*** Regular expressions matching bugs on SCO systems.
-
-On SCO, there are problems in regexp matching when Emacs is compiled
-with the system compiler.  The compiler version is "Microsoft C
-version 6", SCO 4.2.0h Dev Sys Maintenance Supplement 01/06/93; Quick
-C Compiler Version 1.00.46 (Beta).  The solution is to compile with
-GCC.
-
-*** UnixWare 2.1: Error 12 (virtual memory exceeded) when dumping Emacs.
-
-Paul Abrahams (abrahams@acm.org) reports that with the installed
-virtual memory settings for UnixWare 2.1.2, an Error 12 occurs during
-the "make" that builds Emacs, when running temacs to dump emacs.  That
-error indicates that the per-process virtual memory limit has been
-exceeded.  The default limit is probably 32MB.  Raising the virtual
-memory limit to 40MB should make it possible to finish building Emacs.
-
-You can do this with the command `ulimit' (sh) or `limit' (csh).
-But you have to be root to do it.
-
-According to Martin Sohnius, you can also retune this in the kernel:
-
-    # /etc/conf/bin/idtune SDATLIM 33554432         ## soft data size limit
-    # /etc/conf/bin/idtune HDATLIM 33554432         ## hard "
-    # /etc/conf/bin/idtune SVMMSIZE unlimited       ## soft process size limit
-    # /etc/conf/bin/idtune HVMMSIZE unlimited       ## hard "
-    # /etc/conf/bin/idbuild -B
-
-(He recommends you not change the stack limit, though.)
-These changes take effect when you reboot.

-
-`perl -de 0' just hangs when executed in an Emacs subshell.

-The problem is that the Perl debugger explicitly opens a connection to

-
-On Unix, this is okay, because Emacs (or the shell?) creates a

-
-On NT, this fails because CON always refers to the handle for the

+
+This message occurs when the system runs out of swap space due to too

+swap space or to reduce the number of large programs being run.  You
+can check the current status of the swap space by executing the
+command `swap -l'.
+
+You can increase swap space by changing the file /etc/fstab.  Adding a
+line like this:
+
+/usr/swap/swap.more     swap    swap    pri=3 0 0
+
+where /usr/swap/swap.more is a file previously created (for instance
+by using /etc/mkfile), will increase the swap space by the size of
+that file.  Execute `swap -m' or reboot the machine to activate the
+new swap area.  See the manpages for `swap' and `fstab' for further
+information.
+
+The objectserver daemon can use up lots of memory because it can be
+swamped with NIS information.  It collects information about all users
+on the network that can log on to the host.
+
+If you want to disable the objectserver completely, you can execute
+the command `chkconfig objectserver off' and reboot.  That may disable
+some of the window system functionality, such as responding CDROM
+icons.
+
+You can also remove NIS support from the objectserver.  The SGI `admin'

+
+*** SCO Unix and UnixWare
+
+**** SCO 3.2v4: Unusable default font.
+
+The Open Desktop environment comes with default X resource settings
+that tell Emacs to use a variable-width font.  Emacs cannot use such
+fonts, so it does not work.
+
+This is caused by the file /usr/lib/X11/app-defaults/ScoTerm, which is
+the application-specific resource file for the `scoterm' terminal
+emulator program.  It contains several extremely general X resources
+that affect other programs besides `scoterm'.  In particular, these
+resources affect Emacs also:
+
+        *Font: -*-helvetica-medium-r-*--12-*-p-*
+        *Background:                    scoBackground
+        *Foreground:                    scoForeground
+
+The best solution is to create an application-specific resource file for
+Emacs, /usr/lib/X11/sco/startup/Emacs, with the following contents:
+
+        Emacs*Font:     -*-courier-medium-r-*-*-*-120-*-*-*-*-iso8859-1
+        Emacs*Background:       white
+        Emacs*Foreground:       black
+
+(These settings mimic the Emacs defaults, but you can change them to
+suit your needs.)  This resource file is only read when the X server
+starts up, so you should restart it by logging out of the Open Desktop
+environment or by running `scologin stop; scologin start` from the shell
+as root.  Alternatively, you can put these settings in the
+/usr/lib/X11/app-defaults/Emacs resource file and simply restart Emacs,
+but then they will not affect remote invocations of Emacs that use the
+Open Desktop display.
+
+These resource files are not normally shared across a network of SCO
+machines; you must create the file on each machine individually.
+
+**** SCO 4.2.0: Regular expressions matching bugs on SCO systems.
+
+On SCO, there are problems in regexp matching when Emacs is compiled
+with the system compiler.  The compiler version is "Microsoft C
+version 6", SCO 4.2.0h Dev Sys Maintenance Supplement 01/06/93; Quick
+C Compiler Version 1.00.46 (Beta).  The solution is to compile with
+GCC.
+
+**** UnixWare 2.1: Error 12 (virtual memory exceeded) when dumping Emacs.
+
+Paul Abrahams (abrahams@acm.org) reports that with the installed
+virtual memory settings for UnixWare 2.1.2, an Error 12 occurs during
+the "make" that builds Emacs, when running temacs to dump emacs.  That
+error indicates that the per-process virtual memory limit has been
+exceeded.  The default limit is probably 32MB.  Raising the virtual
+memory limit to 40MB should make it possible to finish building Emacs.
+
+You can do this with the command `ulimit' (sh) or `limit' (csh).
+But you have to be root to do it.
+
+According to Martin Sohnius, you can also retune this in the kernel:
+
+    # /etc/conf/bin/idtune SDATLIM 33554432         ## soft data size limit
+    # /etc/conf/bin/idtune HDATLIM 33554432         ## hard "
+    # /etc/conf/bin/idtune SVMMSIZE unlimited       ## soft process size limit
+    # /etc/conf/bin/idtune HVMMSIZE unlimited       ## hard "
+    # /etc/conf/bin/idbuild -B
+
+(He recommends you not change the stack limit, though.)
+These changes take effect when you reboot.

+*** MS-Windows NT/95: Problems running Perl under Emacs
+
+`perl -de 0' just hangs when executed in an Emacs subshell.
+The fault lies with Perl (indirectly with Windows NT/95).
+
+The problem is that the Perl debugger explicitly opens a connection to
+"CON", which is the DOS/NT equivalent of "/dev/tty", for interacting
+with the user.
+
+On Unix, this is okay, because Emacs (or the shell?) creates a
+pseudo-tty so that /dev/tty is really the pipe Emacs is using to
+communicate with the subprocess.
+
+On NT, this fails because CON always refers to the handle for the
+relevant console (approximately equivalent to a tty), and cannot be
+redirected to refer to the pipe Emacs assigned to the subprocess as
+stdin.
+
+A workaround is to modify perldb.pl to use STDIN/STDOUT instead of CON.
