Introduction

gjots2 is a jotter application for your desktop.

Why do we need yet another jotter program? Well, when my faithful
old Psion-5 organiser died I needed to move all my bits and pieces
onto Linux and I started to look around for software to fill that
need. I found lots of software for diary and I already wrote a
beaut calculator (gdcalc) but somehow nothing was quite right for
the jotter.

Other packages that I looked at were either:

* much too simplistic (eg. a single level hierarchy), 
* too complex (too many components like Corba, SQL or 
  suchlike)
* web based
* unable to display & work on the tree at the same time as 
  the text entries
* too messy - throwing windows up like 3M yellow stickers 
  all over the screen

Then there were the ones I couldn't get to work or which just
plain bombed. 

Nonetheless, there are many fine packages around but none really
suited my needs. kjots seemed at the time to be the best of the lot.

Anyhow, I needed to learn how to do GTK trees and practise glade -
and so gjots was born and lives still. It was originally written
in C (now Python), glade and gtk, was pretty fast and is still
something I use every day.  Judging by the emails I've been sent
it is quite useful to others too, which is nice. There was even a
Japanese version created from an early cut of gjots (0.3?) but the
code was never contributed back to the mainstream which is a shame.

However the world doesn't stop still and GTK-2 came along and
there was an increasing number of people who wanted LOTE
(Languages Other Than English) including myself. I also wanted to
learn about python and hence the current python version of gjots
- gjots2 or "son of gjots" came into being. Being written in an
interpreted language it isn't quite so fast to start up as the
original gjots* but it offers heaps more features:

Like Goldilocks said about the chairs, porridge and beds, 
gjots2 is "just right". 

* this was true when I wrote this in about 2004. In 2012, my i7
brings it up practically instantly.

Installing

If possible, use RPM or emerge (Gentoo) - they allow easy
uninstallation and more package management than setup.py
\NewFolder
\NewEntry
RPM-based systems

fedora includes gjots2

Just download and do this:

VERSION=_VERSION_
wget http://bhepple.freeshell.org/gjots/gjots2-${VERSION}-1.noarch.rpm
yum install gjots2-${VERSION}-1.noarch.rpm

\NewEntry
Prerequisites

Let rpm take the strain ... otherwise ...

Install pygtksourceview to enable Undo/Redo

You may need to install (or re-install) libglade, pygtk, or gtk for
your current version of python or possibly you can just set your
PYTHONPATH eg.

	export PYTHONPATH=/usr/local/lib/python2.6/site-packages/

As at this writing (gjots-2.3.11), I have the following installed (on Fedora-13):

    gtk2
    gtksourceview
    libglade2
    pygtk2
    pygtk2-libglade
    pygtksourceview
    glade3-libgladeui

Make sure the python packages are installed in the site-packages
directory for the version of python that you are using (do a "python
-V" to find out the version):

	/usr/lib/pythonX.X/site-packages

If they're not there then you may need to re-install them - for
example, it happened to me when python got upgraded from 2.2 to
2.3 - /usr/lib/python2.X/site-packages directory is not
automatically updated.) I then had to (on gentoo) do this:

	emerge unmerge libglade pygtk bonobo-python pyorbit
	emerge libglade pygtk bonobo-python pyorbit

gjots2 was written with glade-3 so if you want to change or fix the
code you will need to install it too.  Otherwise, it's just python!
\NewEntry
Gentoo 

Note: 2.6.8 and earlier were tested on gentoo. 2.6.9 and on were not.

Until and unless gjots2 has an official ebuild (look in
/usr/portage/app-office) you'll have to do this:

Packages needed on gentoo are (in dependency order - it might be
less trouble to install them from the right hand side of this
list and let the Gentoo dependency system take care of modules to
the left - but I haven't tried it):

	 >=gtk+-2 >=libglade-2 >=pygtk-2 >=pyorbit-2

Make sure you have a line like the following in your /etc/make.conf:

PORTDIR_OVERLAY=/usr/local/portage

You will need a line like this in /etc/portage/packages.keywords:
app-office/gjots2 ~x86

Then:	

VERSION=_VERSION_
CAT=/usr/local/portage/app-office/gjots2
cd /usr/portage/distfiles
wget http://bhepple.freeshell.org/gjots/gjots2-${VERSION}.tgz
mkdir -p ${CAT}
cd ${CAT}
wget http://bhepple.freeshell.org/gjots/gjots2-${VERSION}.ebuild
ebuild ${CAT}/gjots2-${VERSION}.ebuild digest
emerge gjots2

\NewEntry
From the tarball source

VERSION=_VERSION_
wget http://bhepple.freeshell.org/gjots/gjots2-${VERSION}.tgz

If installing from the tarball, after unpacking the tar file and
cd'ing to it do this:

	python setup.py install [ --prefix=/usr/... ]

Uninstall with the uninstall.sh script provided here.

On some systems, you may have permission problems with system-wide
installations from source. All new directories installed should have
permissions 0755, and all installed files should have permissions
0644, with the exception of 'docbook2gjots', 'gjots2',
'gjots2docbook', 'gjots2emacs' and 'gjots2html', which should have
permissions 0755.

Startup

Just start it as "gjots2" - it will save anything in $HOME/.gjotsfile

Or use an argument - gjots2 accepts a single file, eg:

	gjots2 todo.gjots

These options are available:
-h, --help:                         this help
-d, --debug:                        debug to stdout
-2, --glade2:                       use glade-2 gui if available
-t, --trace:                        trace lines as they execute
-g 123x456, --geometry=123x456:     initial geometry (X x Y)
-p, --purge-password                scrub password as soon as it's used
-r, --readonly:                     no editing (or locking)
-V, --version:                      print the version and exit

For supported languages other than English, you can use eg:
	LC_ALL=de_DE.utf8 gjots2
or (eg fedora-16+):
    LANGUAGE=de_DE.utf8 gjots2

To see what languages are currently supported:
	ls /usr/{,local/}share/locale/*/LC_MESSAGES/gjots2.mo

\NewEntry
Open and save

Open and save do the usual and operate on gjots-format text
files (see below).

Unless readonly mode is in effect, gjots2 will create a lockfile
to enforce single-writer but allow multiple readers. If a file is
opened while it is already locked then a popup window will offer
"Try Again" or "Readonly". The "Try Again" option allows you to
exit the program which is locking the file. The lock file is a
simple file called .#filename, where filename is the name of the
gjots2 file being edited. It is in the same directory as the
original gjots2 file and it contains just the process identifier
(pid) of the locking process. If the locking process dies without
cleaning up the lockfile then gjots2 can detect it on the next
open.

Thus, locking is viable even on an NFS mounted volume.

Files opened "readonly" have no locking applied.

There is a menu item under "Files" which allows the readonly
status of the program to be toggled. It also takes care of
locking and unlocking the file as above.

When gjots2 saves a file it moves any prior version of the file to
a backup in the manner of emacs ie. if saving to "file.gjots" 
which already exists, the old version would get saved to 
"file.gjots~"

If your filename ends in ".cpt", gjots will attempt to decrypt
and encrypt the file using ccrypt(1). If ccrypt is not installed
(it is not a standard part of all Linux distributions) the IO will
fail.

Similiarly, .ssl will be opened using (DES3) openssl and .gpg will be
opened with (DES3) gpg.

Install ccrypt, openssl or gpg for good security!
\NewEntry
Controls

The screen has a menubar and toolbar at the top which should be
fairly self-explanatory.

The toolbar on the left controls the tree hierarchy. Just play 
around with it and you'll soon get the hang of it.

"New Page" create a new sibling of the current page.

"New Child" creates a new child of the current item.

"Up" Moves the current selection to before the previous sibling.

"Down" does the opposite of Up.

"Back" makes the currently selected item(s) into children of
their grandparent (or, if you prefer, siblings of their parent).

"Forward" makes the current items(s) into children of the sibling
immediately before them.

"Split item" takes the currently selected text (in the right hand
panel) and moves it into a new item.

"Merge Items" merges the text of all currently selected items
into one big item (separated by a newline character)

"Hide All" collapses the view of the tree to just the children of
the root item.

"Show All" expands all the children of the currently selected
items (recursively).

"Sort Tree" brings up the sort dialog box where you can sort elements
based on a given criteria.

When a folder loses all of its child items it gets automatically 
demoted to a plain item.

On the top toolbar, we have:

"Save" is the usual thing.

The 'Print' button pops up the Print dialog. See the "Printing" item
one level up from here.

The "Undo" and "Redo" functions only operate on the text buffer, not on
the tree. They are only available if the gtksourceview library is available.

"Cut", "Paste" and "Copy" have dual functionality, thus, they
operate on both text and tree items based on whether the text or
tree panels are selected.

The "Wrap" button formats the current paragraph according to the
line length set in the preferences dialog (also activated by ^L)

The "Ext.Ed" button invokes an external editor according to the
command string in the Preferences dialog. The default string is
either 'nedit %s', 'xedit %s' or 'xterm -e vi %s' - depending on
what is installed on the system - the %s is replaced by the
temporary filename. Any other editor can be used as long as it
can accept a filename as an argument - personally, I prefer
"emacsclient %s".

The "Date" button puts a date stamp into the file at the current
position. You can adjust the format of the date stamp in the
Preferences dialog - it uses the date format from strftime(3) -
please check the manual for full details. Some popular choices:

    %F          : (2002-11-03) ... this is the default
    %c          : Sun 03 Nov 2002 10:33:22 AM EST
    (%d %b %y)  : (03 Nov 02)
    %d/%m/%Y    : 28/07/2007

The "Find" button pops up the find & replace dialog. 

"Sort" pops up the sort dialog.

"Prefs" button will pop up the preferences dialog.
\NewEntry
Find & Replace

^F, Edit->Find or the Find button in the top toolbar popup the
find & replace dialog. The top toolbar also holds the most recent find string and quick forward and back search buttons. There is a drop-down of recent searches to the right of this.

^G is a shortcut for 'next' and Shift-^G is for 'previous'.

The operation should be intuitive - type in what you want to find
into the Find & Replace dialog Find entry and press the Find
button.

To replace one occurance put the new text in the Replace entry
box and press the Replace button. The program will search forward
- press it again and it will and replace the text and search
forward again.

To replace all occurances (from the current position to the end of
file) press the Replace All button.

The Close and Cancel button both hide the find dialog - the close
button saves any new settings for future use (except for the Find and
Replace strings).

The Clear button just clears the Find & Replace entries.

Any errors appear both in the area immediately below the button and
also in the main program status bar.

Options appear below the Find & Replace buttons and include "Match
Case" to limit the search to the same upper and lower case. "Global"
is the default and allows the search to take place across the whole
file. The alternative is to limit the search to the current item.
"Regular Expression" permits the use of POSIX Extended Regular
Expressions as defined in "man 7 regex" (ie as used in egrep).

A quick reference to regular expressions (note that gjots2 uses
Python's re package - see the Python docs for full details, it is
rather simpler than the regex used in the C version of gjots):

.	any character
^	start of line (only as the first item in the RE)
$	end of line (only as the last item in the RE)

*	zero or more repetitions of the previous RE
+	one or more repetitions of the previous RE
?	zero or one repetitions of the previous RE
{n}	exactly n repetitions of the previous RE
{n,}	n or more repetitions of the previous RE
{n,m}	n to m repetitions of the previous RE
[ ]	matches any character in the set. Ranges are eg. [a-z]
[^ ]	matches any character not in the set
(  )	forms a 'remembered' pattern
|	pattern alternation eg. x|y means "matches x or y"
\n	n is 1 to 9 - a backreference to a previous pattern

\b	start or end of a word
\d	a digit == [0-9]
\s	whitespace == [ \t\n\r\f\v]
\S	non-whitespace
\w	alphanumeric
\W	non-alphanumeric

To match one of the 'magic' characters ^.[$()|*+?{\ escape it
with \

For the replacement pattern the following sequences are
available:

\&	paste the entire found string
\1..\9	paste the nth found sub-pattern (defined with (...) )
\n	insert a newline
\NewEntry
Printing 

The Print dialog lets you select "what to print":
	the current page,
	the current selection or 
	the whole thing

and a few enhancements:
	page feed after every gjots item and 
	auto numbering (not actually implemented yet)

The print command that ships with 2.3.7 and later is "gjots2lpr" which
is a simple script to try to find useful printing tools and to use
them. The default operation is to pass the text through "a2ps" and to
view the result with "gv". If these programs are not installed, others
are sought - see "gjots2lpr -h" for more details.

Before 2.6.7 the default print comman was rather long, but it expanded
to the following which is supposed to do something similar:

if type gv; then 
  GV='gv -seascape'
else 
  if type ggv; then 
    GV=ggv; 
  else 
    lpr $1
    exit
  fi
fi 
T=/tmp/.tmp.$$
mpage -f -2 -I1 -P- $1 > $T
($GV $T; rm $T)&

Some possible suggestions for the "Print command" instead of the default:

To simply send the raw output directly to the printer:
lpr $1
\NewEntry
Preferences

The following items can be selected as preferences by gconf:

Text formatter - default is "fmt -w %d"

Text line length - used in paragraph formating, (65)

External Editor - editor to use with the Ext.Ed. button eg.:
nedit %s
xedit %s
xterm -e vi %s
emacsclient %s

Date format - format string to feed to strftime(3) for use in
date stamp. Do a "man strftime" for details. e.g.: 

    %F          : (2002-11-03) ... this is the default
    %c          : Sun 03 Nov 2002 10:33:22 AM EST
    (%d %b %y)  : (03 Nov 02)
    %d/%m/%Y    : 28/07/2007

Font - the font to be used for the text display. The controls and
tree still use the default GTK-2 fonts.

\NewEntry
Keyboard operation

Most of the key shortcuts are the usual. In the text display, the
normal GTK-2 key mappings apply (slightly different to the C/GTK-1
version of gjots):

	^a			Select all text
	home			goto start of line
	end			goto end of line
	left			move back one place
	right			move forward one place
	^left			move one word left
	^right			move one word right
	down			move to next line
	up			move to previous line
	^home/end		goto start/end of text

	delete			delete one char
	backspace		delete one char backwards
	^L			paragraph re-format or "wrap" 

Shift and <move> mark the region.

Plus the following work:

	^x			cut
	^c			copy
	^v			paste

Key mappings in the tree:

In general, plain keys just move around the tree.
Control keys manipulate the tree.

	up		goto previous item
	down		goto next item
	^up		move the current item(s) up the tree
	^down		move the current item(s) down the tree
	shift-up/down	extend the selection
	left		ascend the tree
	right		descend the tree
	^left		promote items
	^right		demote items
	home		goto to the first item at the present level
	end		goto to the last item at the present level
	^home		goto the very first item
	^end		goto the very last (expanded) item

Global key mappings:
	^s		does save
	^q		does quit
	^f		Popup the find dialog
        ^g              find next
        shift-^g        find previous
\NewEntry
Import and export

You can bring data in and out of gjots2 using the import and 
export functions. These operate on the currently selected 
item so you can control exactly what gets saved.

The format of the file is the normal gjots2 format.
\NewEntry
gjots2 file format

The same as gjots which is plain text but with a hierarchy introduced
by some keywords:

    \NewEntry
    title1
    this is the stuff that goes into title1

    \NewFolder
    \NewEntry 
    title2
    this is title2's stuff

    \NewEntry 
    title3
    title 3's stuff

    \EndFolder

The \keywords need to be at the start of the line to be 
recognised.
\NewEntry
Encryption

gjots2 can encrypt and decrypt files using the ccrypt(1), openssl(1),
gpg2(1) or gpg(1) packages. If the gpg-agent is detected (ie if
the GPG_AGENT_INFO variable is set) then it is used for passwords.

Files are saved with encryption according to the file suffix you
provide:

.cpt ccrypt
.ssl openssl
.gpg gpg

gjots2 prompts for passwords where needed.

Make sure you have ccrypt, openssl, gpg2 or gpg installed if you want
to use this feature.

Don't lose your password - I can't help you recover lost
passwords!!
\NewEntry
Security

gjots2 has not been audited for security, so don't assume it
is secure. That said, it's probably secure enough for most
private use. The static, encrypted files on disc are as good as
gpg/openssl/ccrypt, ie pretty good, (the default algorithm and key lengths are used in each encryption program).

For encryption in ccrypt, I've used the equivalent of:
 
    {write cleartext} | KEYWORD=password ccencrypt -E KEYWORD >filename.cpt
  
This exposes the password briefly as an environment 
parameter although it is 'scrubbed' and removed from the 
gjots2 process environment immediately after use. According 
to the ccrypt man page, "on most modern systems" the ps 
command protects environment parameters from ordinary 
users. Under Linux, you can 'cat /proc/PID/environ' to see 
the environment parameters of any process that you own - 
only root can spy on another's environment so using -E is no 
less secure than your login password and root's login 
password.
 
The only other way to do this (AFAICS) would be:

	{write cleartext} >file.gjot 
	echo password |ccencrypt -k - file.gjot
 
 ... while this provides better protection for the password, this
(briefly) exposes the cleartext as a file - as bad as or worse 
than exposing the key as an environment parameter!

Decrypting is much easier - I use stdin to pass in the 
password:

     echo password |ccdecrypt -c -k - filename.cpt | {read from pipe}
 
A supplementary channel (eg. stdin=0, stdout=1 stderr=3
stdpasswd=3) for ccrypt to read passwords would be a better
solution (but ccrypt does not provide it).

     59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
 Everyone is permitted to copy and distribute verbatim copies
 of this license document, but changing it is not allowed.

			    Preamble

  The licenses for most software are designed to take away your
freedom to share and change it.  By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users.  This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it.  (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.)  You can apply it to
your programs, too.

  When we speak of free software, we are referring to freedom, not
price.  Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.

  To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.

  For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have.  You must make sure that they, too, receive or can get the
source code.  And you must show them these terms so they know their
rights.

  We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.

  Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software.  If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.

  Finally, any free program is threatened constantly by software
patents.  We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary.  To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.

  The precise terms and conditions for copying, distribution and
modification follow.

		    GNU GENERAL PUBLIC LICENSE
   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

  0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License.  The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language.  (Hereinafter, translation is included without limitation in
the term "modification".)  Each licensee is addressed as "you".

Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope.  The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.

  1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.

You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.

  2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:

    a) You must cause the modified files to carry prominent notices
    stating that you changed the files and the date of any change.

    b) You must cause any work that you distribute or publish, that in
    whole or in part contains or is derived from the Program or any
    part thereof, to be licensed as a whole at no charge to all third
    parties under the terms of this License.

    c) If the modified program normally reads commands interactively
    when run, you must cause it, when started running for such
    interactive use in the most ordinary way, to print or display an
    announcement including an appropriate copyright notice and a
    notice that there is no warranty (or else, saying that you provide
    a warranty) and that users may redistribute the program under
    these conditions, and telling the user how to view a copy of this
    License.  (Exception: if the Program itself is interactive but
    does not normally print such an announcement, your work based on
    the Program is not required to print an announcement.)

These requirements apply to the modified work as a whole.  If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works.  But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.

Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.

In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.

  3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:

    a) Accompany it with the complete corresponding machine-readable
    source code, which must be distributed under the terms of Sections
    1 and 2 above on a medium customarily used for software interchange; or,

    b) Accompany it with a written offer, valid for at least three
    years, to give any third party, for a charge no more than your
    cost of physically performing source distribution, a complete
    machine-readable copy of the corresponding source code, to be
    distributed under the terms of Sections 1 and 2 above on a medium
    customarily used for software interchange; or,

    c) Accompany it with the information you received as to the offer
    to distribute corresponding source code.  (This alternative is
    allowed only for noncommercial distribution and only if you
    received the program in object code or executable form with such
    an offer, in accord with Subsection b above.)

The source code for a work means the preferred form of the work for
making modifications to it.  For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable.  However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.

If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.

  4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License.  Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.

  5. You are not required to accept this License, since you have not
signed it.  However, nothing else grants you permission to modify or
distribute the Program or its derivative works.  These actions are
prohibited by law if you do not accept this License.  Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.

  6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions.  You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.

  7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License.  If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all.  For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.

If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.

It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices.  Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.

This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.

  8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded.  In such case, this License incorporates
the limitation as if written in the body of this License.

  9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time.  Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.

Each version is given a distinguishing version number.  If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation.  If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.

  10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission.  For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this.  Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.

			    NO WARRANTY

  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.

  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
