[comp.emacs] VM 4.11

kjones@talos.UUCP (Kyle Jones) (05/30/89)

[ My mailbox overflows.  Something went wrong with the initial VM
  posting.  Here it is again, via a different route.

  Even if you received all of the first posting, use this version.
  Among other things the Info document grew indices, and VM has learned
  how to deal with MMDF folders. --kyle ]

This is the first of four messages containing the Emacs-Lisp source and
documentation for the VM (View Mail) mail reader.

Those of you who've wanted to read mail under Emacs but didn't want to
expose your mail folders to RMAIL will be cheered to hear that VM works
with UNIX style mail folders in their original format.

Thanks go to my faithful beta-testers, Tad Guy, Mike Walker, and Scott
Yelich who cheerfully abused VM and imperiled their mail in VM's
unstable early days.

`M-x vm' gets you going.  Type a ? for help.  There's an Info document
if you care to go that route, but the help should be enough for most.

MMDF users should (setq vm-folder-type 'mmdf) in their .emacs files.
Thanks go to Wolfgang Rupprecht for pointing out the simple changes
needed to provide the support.

Users with multiple spool files, or spool files in strange locations
should check the variable `vm-spool-files'.

Send suggestions and bug reports to one of the e-mail addresses below.

X                    675 Mass Ave, Cambridge, MA 02139, USA
X Everyone is permitted to copy and distribute verbatim copies
X of this license document, but changing it is not allowed.
X
X			    Preamble
X
X  The license agreements of most software companies try to keep users
Xat the mercy of those companies.  By contrast, our General Public
XLicense is intended to guarantee your freedom to share and change free
Xsoftware--to make sure the software is free for all its users.  The
XGeneral Public License applies to the Free Software Foundation's
Xsoftware and to any other program whose authors commit to using it.
XYou can use it for your programs, too.
X
X  When we speak of free software, we are referring to freedom, not
Xprice.  Specifically, the General Public License is designed to make
Xsure that you have the freedom to give away or sell copies of free
Xsoftware, that you receive source code or can get it if you want it,
Xthat you can change the software or use pieces of it in new free
Xprograms; and that you know you can do these things.
X
X  To protect your rights, we need to make restrictions that forbid
Xanyone to deny you these rights or to ask you to surrender the rights.
XThese restrictions translate to certain responsibilities for you if you
Xdistribute copies of the software, or if you modify it.
X
X  For example, if you distribute copies of a such a program, whether
Xgratis or for a fee, you must give the recipients all the rights that
Xyou have.  You must make sure that they, too, receive or can get the
Xsource code.  And you must tell them their rights.
X
X  We protect your rights with two steps: (1) copyright the software, and
X(2) offer you this license which gives you legal permission to copy,
Xdistribute and/or modify the software.
X
X  Also, for each author's protection and ours, we want to make certain
Xthat everyone understands that there is no warranty for this free
Xsoftware.  If the software is modified by someone else and passed on, we
Xwant its recipients to know that what they have is not the original, so
Xthat any problems introduced by others will not reflect on the original
Xauthors' reputations.
X
X  The precise terms and conditions for copying, distribution and
Xmodification follow.
X
X		    GNU GENERAL PUBLIC LICENSE
X   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
X
X  0. This License Agreement applies to any program or other work which
Xcontains a notice placed by the copyright holder saying it may be
Xdistributed under the terms of this General Public License.  The
X\"Program\", below, refers to any such program or work, and a \"work based
Xon the Program\" means either the Program or any work containing the
XProgram or a portion of it, either verbatim or with modifications.  Each
Xlicensee is addressed as \"you\".
X
X  1. You may copy and distribute verbatim copies of the Program's source
Xcode as you receive it, in any medium, provided that you conspicuously and
Xappropriately publish on each copy an appropriate copyright notice and
Xdisclaimer of warranty; keep intact all the notices that refer to this
XGeneral Public License and to the absence of any warranty; and give any
Xother recipients of the Program a copy of this General Public License
Xalong with the Program.  You may charge a fee for the physical act of
Xtransferring a copy.
X
X  2. You may modify your copy or copies of the Program or any portion of
Xit, and copy and distribute such modifications under the terms of Paragraph
X1 above, provided that you also do the following:
X
X    a) cause the modified files to carry prominent notices stating that
X    you changed the files and the date of any change; and
X
X    b) cause the whole of any work that you distribute or publish, that
X    in whole or in part contains the Program or any part thereof, either
X    with or without modifications, to be licensed at no charge to all
X    third parties under the terms of this General Public License (except
X    that you may choose to grant warranty protection to some or all
X    third parties, at your option).
X
X    c) If the modified program normally reads commands interactively when
X    run, you must cause it, when started running for such interactive use
X    in the simplest and most usual way, to print or display an
X    announcement including an appropriate copyright notice and a notice
X    that there is no warranty (or else, saying that you provide a
X    warranty) and that users may redistribute the program under these
X    conditions, and telling the user how to view a copy of this General
X    Public License.
X
X    d) You may charge a fee for the physical act of transferring a
X    copy, and you may at your option offer warranty protection in
X    exchange for a fee.
X
XMere aggregation of another independent work with the Program (or its
Xderivative) on a volume of a storage or distribution medium does not bring
Xthe other work under the scope of these terms.
X
X  3. You may copy and distribute the Program (or a portion or derivative of
Xit, under Paragraph 2) in object code or executable form under the terms of
XParagraphs 1 and 2 above provided that you also do one of the following:
X
X    a) accompany it with the complete corresponding machine-readable
X    source code, which must be distributed under the terms of
X    Paragraphs 1 and 2 above; or,
X
X    b) accompany it with a written offer, valid for at least three
X    years, to give any third party free (except for a nominal charge
X    for the cost of distribution) a complete machine-readable copy of the
X    corresponding source code, to be distributed under the terms of
X    Paragraphs 1 and 2 above; or,
X
X    c) accompany it with the information you received as to where the
X    corresponding source code may be obtained.  (This alternative is
X    allowed only for noncommercial distribution and only if you
X    received the program in object code or executable form alone.)
X
XSource code for a work means the preferred form of the work for making
Xmodifications to it.  For an executable file, complete source code means
Xall the source code for all modules it contains; but, as a special
Xexception, it need not include source code for modules which are standard
Xlibraries that accompany the operating system on which the executable
Xfile runs, or for standard header files or definitions files that
Xaccompany that operating system.
X
X  4. You may not copy, modify, sublicense, distribute or transfer the
XProgram except as expressly provided under this General Public License.
XAny attempt otherwise to copy, modify, sublicense, distribute or transfer
Xthe Program is void, and will automatically terminate your rights to use
Xthe Program under this License.  However, parties who have received
Xcopies, or rights to use copies, from you under this General Public
XLicense will not have their licenses terminated so long as such parties
Xremain in full compliance.
X
X  5. By copying, distributing or modifying the Program (or any work based
Xon the Program) you indicate your acceptance of this license to do so,
Xand all its terms and conditions.
X
X  6. Each time you redistribute the Program (or any work based on the
XProgram), the recipient automatically receives a license from the original
Xlicensor to copy, distribute or modify the Program subject to these
Xterms and conditions.  You may not impose any further restrictions on the
Xrecipients' exercise of the rights granted herein.
X
X  7. The Free Software Foundation may publish revised and/or new versions
Xof the General Public License from time to time.  Such new versions will
Xbe similar in spirit to the present version, but may differ in detail to
Xaddress new problems or concerns.
X
XEach version is given a distinguishing version number.  If the Program
Xspecifies a version number of the license which applies to it and \"any
Xlater version\", you have the option of following the terms and conditions
Xeither of that version or of any later version published by the Free
XSoftware Foundation.  If the Program does not specify a version number of
Xthe license, you may choose any version ever published by the Free Software
XFoundation.
X
X  8. If you wish to incorporate parts of the Program into other free
Xprograms whose distribution conditions are different, write to the author
Xto ask for permission.  For software which is copyrighted by the Free
XSoftware Foundation, write to the Free Software Foundation; we sometimes
Xmake exceptions for this.  Our decision will be guided by the two goals
Xof preserving the free status of all derivatives of our free software and
Xof promoting the sharing and reuse of software generally.
X
X			    NO WARRANTY
X
X  9. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
XFOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
XOTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
XPROVIDE THE PROGRAM \"AS IS\" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
XOR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
XMERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
XTO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
XPROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,

X@chapter Introduction
X
XVM (View Mail) is an Emacs subsystem that allows UNIX mail to be read
Xand disposed of within Emacs.  Commands exist to do the normal things
Xexpected of a mail user agent, such as generating replies, saving
Xmessages to folders, deleting messages and so on.  There are other more
Xadvanced commands that do tasks like bursting and creating digests,
Xmessage forwarding, and organizing message presentation according to
Xvarious criteria.
X
XTo invoke VM simply type @kbd{M-x vm}.  VM gathers any mail that has
Xarrived in your system mailbox and appends it to a file known as your
X@dfn{primary inbox}, and visits that file for reading.  @xref{Starting Up}.
XA file visited for reading by VM is called the @dfn{current folder}.@refill
X
X@findex vm-scroll-forward
X@findex vm-scroll-backward
X@kindex SPC
X@kindex b
XIf there are any messages in the primary inbox, VM selects the first new
Xor unread message, and previews it.  @dfn{Previewing} is VM's way of
Xshowing you part of message and allowing you to decide whether you want
Xto read it.  @xref{Previewing}.  By default VM shows you the message's
Xsender, recipient, subject and date headers.  Typing @key{SPC}
X(@code{vm-scroll-forward}) exposes the body of the message and marks the
Xmessage as read.  Subsequent @key{SPC}'s scroll forward through the
Xmessage, @kbd{b} scrolls backward.  When you reach the end of a message,
Xtyping a @key{SPC} or @kbd{n} moves you forward to preview the next
Xmessage.@refill
X
XIf you do not want to read a message that's being previewed, just type
X@kbd{n} and VM will move on to the next message (if there is one).
X@xref{Selecting Messages}.@refill
X
XTo save a message to a mail folder use @kbd{s} (@code{vm-save-message}).
XVM will prompt you for the folder name in the minibuffer.
X@xref{Saving Messages}.@refill
X
XMessages are deleted by typing @kbd{d} (@code{vm-delete-message}) while
Xpreviewing or reading them.  The message is not deleted right away; it
Xis simply marked for deletion.  If you change your mind about deleting a
Xmessage just select it and type @kbd{u} (@code{vm-undelete-message}),
Xand the message will be undeleted.  @xref{Deleting Messages}.  The
Xactual removal of deleted messages from the current folder is called
X@dfn{expunging} and it is accomplished by typing @kbd{#} (@code{vm-expunge-folder}).  The message is still present in the on-disk
Xversion of the folder until the folder is saved.  @xref{Saving Folders}.@refill
X
XTyping @kbd{h} (@code{vm-summarize}) causes VM to pop up a window
Xcontaining a summary of contents of the current folder.  Each message is
Xsumamrized, one per line, by message number listing its author, date
Xsent, line and byte count, and subject.  Also various letters appear
Xbeside the message number to indicate that a message is new, unread,
Xmarked for deletion, etc.  An arrow @samp{->} appears to the left of the
Xline summarizing the current messge.  The summary format is user
Xconfigurable, @pxref{Summaries}.@refill
X
X@findex vm-save-folder
X@kindex S
XWhen you are finished reading mail the current folder must be saved, so
Xthat the next time the folder is visited VM will know which message have
Xbeen already read, replied to and so on.  Typing @kbd{S}
X(@code{vm-save-folder}) expunges all deleted message and saves the
Xfolder.  @kbd{C-x C-s} saves the folder without expunging deleted
Xmessages but the message are still marked deleted.  The next time the
Xfolder is visited these messages will still be marked for deletion.@refill
X
X@findex vm-quit
X@findex vm-quit-no-change
X@kindex q
X@kindex x
XTo quit VM you can type @kbd{q} (@code{vm-quit}) or @kbd{x}
X(@code{vm-quit-no-change}).  Typing @kbd{q} expunges and saves the
Xcurrent folder before quitting.  Also, any messages marked new are
Xchanged to be marked unread, before saving.  The @kbd{x} command quits
XVM without expunging, saving or otherwise modifying the current folder.
XQuitting is not required; you can simply switch to another Emacs buffer
Xwhen you've finished reading mail.@refill
X
X@findex vm-get-new-mail
X@kindex g
XAt any time while reading mail in the primary inbox you can type @kbd{g}
X(@code{vm-get-new-mail}) to check to see if new mail has arrived.  If
Xnew mail has arrived it will be merged into the primary inbox.  If you
Xare not in the middle of another message, VM will also jump to the first
Xnew message.
X
X@node Starting Up, Selecting Messages, Introduction, Top
X@chapter Starting Up
X
XThere are two ways to start VM: @kbd{M-x vm} and @kbd{M-x vm-visit-folder}.
X
X@findex vm
X@vindex vm-primary-inbox
X@kbd{M-x vm} causes VM to gather any mail present in your system mailbox
Xand append it to a file known as your @dfn{primary inbox}, creating
Xthis file if necessary.  The default name of this file is
X@file{~/INBOX}, but VM will use whatever file is named by the variable
X@code{vm-primary-inbox}.@refill
X
X@vindex vm-crash-box
XVM transfers the mail from the system mailbox to the primary inbox via a
Xtemporary file known as the @dfn{crash box}.  The variable
X@code{vm-crash-box} names the crash box file.  VM first copies the mail
Xto the crash box, deletes the system mailbox, merges the crash box
Xcontents into the primary inbox, and then deletes the crash box.  If the
Xsystem or Emacs should crash in the midst of this transfer, any message
Xno present in the primary inbox will be either in the system mailbox or
Xthe crash box.  Some messages may be duplicated but no mail will be
Xlost.@refill
X

XBy default, the system mailbox is determined heuristically by VM based
Xon what type of system you're using.  VM can be told explicitly where
Xthe system mailbox is through the variable @code{vm-spool-files}.  The
Xvalue of this variable should be a list of strings naming files VM

Xautomatically displays a summary of the folder's contents at startup.  A
Xvalue of @code{nil} gives no summary; a value of @code{t} gives a full
Xscreen summary.  A value that is neither @code{t} nor @code{nil} splits
Xthe screen between the summary and the folder display.  The latter only
Xworks if the variable pop-up-windows's value is non-nil.@refill
X
X@vindex vm-mail-window-percentage
XThe variable @{vm-mail-window-percentage} tells VM what percentage of
Xthe screen should be given the folder display when both it and the
Xfolder summary are being displayed.  Note that Emacs enforces a minimum
Xwindow sizew limit, so a very high or very low value for this variable
Xmay squeeze out one of the displays entirely.  This variable's default
Xvalue is 75, which works with Emacs' default minimum window size limit,

XThe primary commands for selecting messages in VM are @kbd{n}
X(@code{vm-next-message}) and @kbd{p} (@code{vm-previous-message}).
XThese command move forward and backward through the current folder.
XWhen they go beyond the end or beginning of the folder they wrap to the
Xbeginning and end respectively.  By default these commands skip messages
Xmarked for deletion.  This behavior can be disabled by setting the value
Xof the variable @code{vm-skip-deleted-messages} to @code{nil}.  These
Xcommands can also be made to skip message that have been read; set
X@code{vm-skip-read-messages} to @code{t} to do this.  If all the message
Xis the current folder would be skipped (i.e all are read and/or
Xdeleted), @kbd{n} and @kbd{p} simply move to the next message.@refill
X
XThe command @kbd{n} and @kbd{p} also take prefix arguments that specify
Xthe number of message to move forward or backward.  If the magnitude of
Xthe prefix argument is greater than 1, no message skipping will be done
Xregardless of the settings of the previously mentioned skip control
Xvariables.
X
XOther commands to select messages:
X
X@table @key
X@findex vm-goto-message

X@vindex vm-preview-lines
XThe value of @code{vm-preview-lines} should be a number that tells VM
Xhow many lines of the text of the message should be visible.  The default
Xvalue of this variable is 0.  If @code{vm-preview-lines} is @code{nil},
Xthen previewing is not done at all; when a message is first presented it

X
X@findex vm-save-message
X@kindex s
XThe VM command to save a message to a folder is @kbd{s}
X(@code{vm-save-message}); invoking this command causes the current
Xmesage to be saved to a folder that whose name you specify in the
Xminibuffer.  If @code{vm-save-message} is given a prefix argument
X@var{n}, the current message plus the next @var{n}-1 message are saved.

Xmessages are saved.  Messages saved with @code{vm-save-message} are
Xmarked ``filed''.@refill
X
X@vindex vm-folder-directory
XIf you have a directory where you keep all your mail folders, you should
Xset the variable @code{vm-folder-directory} to point to it.  If this
Xvariable is set, @code{vm-save-message} will insert this directory name
Xinto the minibuffer before prompting you for a folder name; this will save
Xyou some typing.@refill

X
XIf any part of the contents of the message header named by
X@var{header-name} is matched by the regular expression @var{regexp}, VM
Xwill use the corresponding @var{folder-name} as the default when
Xprompting for a folder to save the message in.  If @var{folder-name} is

XVM can save messages to a folder in two distinct ways.  The message can
Xbe appended directly to the folder on disk, or the folder can be visited
Xas Emacs would visit any other file and the message be appended to that
Xbuffer.  In the latter method you must save the buffer yourself to
Xchange the on-disk copy of the folder.  The variable
X@code{vm-visit-when-saving} controls which method is used.  A @code{nil}
Xvalue (the default) causes VM to append directly to the folder file, a
Xnon-@code{nil} value makes VM load the file into a buffer and append to
Xthat.@refill

X  0. This License Agreement applies to any program or other work which
Xcontains a notice placed by the copyright holder saying it may be
Xdistributed under the terms of this General Public License.  The
X"Program", below, refers to any such program or work, and a "work based
Xon the Program" means either the Program or any work containing the
XProgram or a portion of it, either verbatim or with modifications.  Each
Xlicensee is addressed as "you".
X
X  1. You may copy and distribute verbatim copies of the Program's source
Xcode as you receive it, in any medium, provided that you conspicuously and
Xappropriately publish on each copy an appropriate copyright notice and
Xdisclaimer of warranty; keep intact all the notices that refer to this
XGeneral Public License and to the absence of any warranty; and give any
Xother recipients of the Program a copy of this General Public License
Xalong with the Program.  You may charge a fee for the physical act of
Xtransferring a copy.
X
X  2. You may modify your copy or copies of the Program or any portion of
Xit, and copy and distribute such modifications under the terms of Paragraph
X1 above, provided that you also do the following:
X
X    a) cause the modified files to carry prominent notices stating that
X    you changed the files and the date of any change; and
X
X    b) cause the whole of any work that you distribute or publish, that
X    in whole or in part contains the Program or any part thereof, either
X    with or without modifications, to be licensed at no charge to all
X    third parties under the terms of this General Public License (except
X    that you may choose to grant warranty protection to some or all
X    third parties, at your option).
X
X    c) If the modified program normally reads commands interactively when
X    run, you must cause it, when started running for such interactive use
X    in the simplest and most usual way, to print or display an
X    announcement including an appropriate copyright notice and a notice
X    that there is no warranty (or else, saying that you provide a
X    warranty) and that users may redistribute the program under these
X    conditions, and telling the user how to view a copy of this General
X    Public License.
X
X    d) You may charge a fee for the physical act of transferring a
X    copy, and you may at your option offer warranty protection in
X    exchange for a fee.
X
XMere aggregation of another independent work with the Program (or its
Xderivative) on a volume of a storage or distribution medium does not bring
Xthe other work under the scope of these terms.
X
X  3. You may copy and distribute the Program (or a portion or derivative of
Xit, under Paragraph 2) in object code or executable form under the terms of
XParagraphs 1 and 2 above provided that you also do one of the following:
X
X    a) accompany it with the complete corresponding machine-readable
X    source code, which must be distributed under the terms of
X    Paragraphs 1 and 2 above; or,
X
X    b) accompany it with a written offer, valid for at least three
X    years, to give any third party free (except for a nominal charge
X    for the cost of distribution) a complete machine-readable copy of the
X    corresponding source code, to be distributed under the terms of
X    Paragraphs 1 and 2 above; or,
X
X    c) accompany it with the information you received as to where the
X    corresponding source code may be obtained.  (This alternative is
X    allowed only for noncommercial distribution and only if you
X    received the program in object code or executable form alone.)
X
XSource code for a work means the preferred form of the work for making
Xmodifications to it.  For an executable file, complete source code means
Xall the source code for all modules it contains; but, as a special
Xexception, it need not include source code for modules which are standard
Xlibraries that accompany the operating system on which the executable
Xfile runs, or for standard header files or definitions files that
Xaccompany that operating system.
X
X  4. You may not copy, modify, sublicense, distribute or transfer the
XProgram except as expressly provided under this General Public License.
XAny attempt otherwise to copy, modify, sublicense, distribute or transfer
Xthe Program is void, and will automatically terminate your rights to use
Xthe Program under this License.  However, parties who have received
Xcopies, or rights to use copies, from you under this General Public
XLicense will not have their licenses terminated so long as such parties
Xremain in full compliance.
X
X  5. By copying, distributing or modifying the Program (or any work based
Xon the Program) you indicate your acceptance of this license to do so,
Xand all its terms and conditions.
X
X  6. Each time you redistribute the Program (or any work based on the
XProgram), the recipient automatically receives a license from the original
Xlicensor to copy, distribute or modify the Program subject to these
Xterms and conditions.  You may not impose any further restrictions on the
Xrecipients' exercise of the rights granted herein.
X
X  7. The Free Software Foundation may publish revised and/or new versions
Xof the General Public License from time to time.  Such new versions will
Xbe similar in spirit to the present version, but may differ in detail to
Xaddress new problems or concerns.
X
XEach version is given a distinguishing version number.  If the Program
Xspecifies a version number of the license which applies to it and "any
Xlater version", you have the option of following the terms and conditions
Xeither of that version or of any later version published by the Free
XSoftware Foundation.  If the Program does not specify a version number of
Xthe license, you may choose any version ever published by the Free Software
XFoundation.
X
X  8. If you wish to incorporate parts of the Program into other free
Xprograms whose distribution conditions are different, write to the author
Xto ask for permission.  For software which is copyrighted by the Free
XSoftware Foundation, write to the Free Software Foundation; we sometimes
Xmake exceptions for this.  Our decision will be guided by the two goals
Xof preserving the free status of all derivatives of our free software and
Xof promoting the sharing and reuse of software generally.
X
X			    NO WARRANTY
X
X  9. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
XFOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
XOTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
XPROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
XOR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
XMERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
XTO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
XPROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
XREPAIR OR CORRECTION.
X
X  10. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
XWILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
XREDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
XINCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
XOUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
XTO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
XYOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
XPROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
XPOSSIBILITY OF SUCH DAMAGES.
