+INSTALL: Installation instructions for XMLterm source code
+----------------------------------------------------------
+
+*NOTE* This is work in progress. User beware!
+
+*NOTE* Check the XMLterm web site <http://xmlterm.org> for updates.
+
+29 Nov 1999
+
+In the following discussion, file and directory names are relative
+to the main ("mozilla/extensions/xmlterm") directory. See the end of the
+README file for a brief description of the subdirectories.
+
+
+1. Source tree (skip this step if XMLterm is already in the source tree)
+------------------------------------------------------------------------
+
+The XMLterm source code is distributed as a tarball, xmlterm.tar.gz
+
+This tar file needs to be untarred in the "mozilla/extensions" directory,
+or any any other "mozilla/dir" directory one level below the top-level.
+A subdirectory called "xmlterm" will be created there.
+("mozilla" denotes the root directory of the Mozilla source tree)
+
+If you have already untarred it elsewhere, simply move the "xmlterm" directory
+to the right place.
+
+
+2. Configuration
+----------------
+
+To recursively create all Makefiles from Makefile.in files, type the following:
+
+makemake -r
+
+The file "config/xmlterm_config.mk" contains XMLterm specific configuration
+information that is needed in addition to any Mozilla configuration
+information. It has already been hand-configured for Linux2.0/Linux2.2, and
+Solaris2.6 platforms. It may need to be modified slightly to compile XMLterm
+on other platforms.
+
+At present XMLterm has been tested only on Linux (RedHat6.0) and Solaris2.6
+platforms, using the M11 release as the base version of Mozilla.
+
+XMLterm typically uses the UNIX pseudo-TTY interface to communicate with the
+shell. At present, this interface is implemented only for Linux and Solaris
+platforms.
+
+XMLterm may compile on other Unix platforms, but it will use NSPR pipes,
+rather than a pseudo-TTY, for process communication; this means that the
+terminal control characters, such as Control-C for interrupting jobs, will not
+work on those platforms. (See the file doc/PORTABILITY for a discussion of
+portability issues)
+
+
+3. Creating the dynamically loaded XPCOM/XPCONNECT component
+------------------------------------------------------------
+
+To create the dynamically loaded XPCOM library, type the following in the main
+directory
+
+  make all
+
+This creates the self-registering library "libxmlterm.so" and installs it in
+the "mozilla/dist/bin/components" directory, along with some chrome
+files. After this step, the following interfaces become accessible in Mozilla
+through XPCOM/XPCONNECT:
+
+  mozIXMLTermShell     (interface to XMLterm)
+  mozILineTerm         (interface to the stand-alone LINETERM)
+
+To clean up completely, type
+
+ make clean
+
+
+4. Using the lightweight "xmlterm" stand-alone program
+----------------------------------------------------
+
+Step 3 creates an executable called "xmlterm" in the "mozilla/dist/bin"
+directory. This is a lightweight program implementing XMLterm using the Gecko
+layout engine only, without the added baggage of the full browser. Executing
+"xmlterm" will create an XMLterm window. Click on this window to give it focus
+before typing Unix commands.
+
+The command line can be edited using EMACS-style key bindings.
+Command completion should also work with TCSH and BASH, as should history
+recall.
+
+**NOTE**
+The command prompt is assumed to be terminated by one of the characters
+"#$%>?", followed by a space. If this is not the case, many features will not
+work. This restriction will be relaxed in the future.
+
+By default, blue coloring is used to indicate clickable display elements.
+Note that the prompt and the input command line are clickable.
+(Of course, the appearance of XMLterm is completely configurable
+using the CSS stylesheet chrome://xmlterm/skin/default/xmlterm.css)
+
+After typing one or two commands, click on the prompt string of any previous
+command to see what happens! Then click again on the same prompt string.
+Also click on "Hide all output" button at the top of the document.
+
+Clicking on a previous command line (to the right of the prompt) re-executes
+the command.
+
+The sample Perl script "xls", the iconic/hypertext version of the Unix "ls"
+command, is in the "tests" directory. Copy it to some directory in your path
+to use it.
+
+Note: At present, xmlterm only works with the GTK front end.
+
+
+5. Creating an XMLterm window using the browser
+-----------------------------------------------
+
+At this time, XMLterm cannot be accessed through the menu bar. Instead, load
+the URL "chrome://xmlterm/content/xmlterm.html" in the browser, either at the
+command line or by typing it in the URL box. Then click on the browser window
+with the mouse to shift focus and then start typing UNIX commands.
+
+
+6. Stand-alone mode (optional)
+------------------------------
+
+Although XMLterm resides in the Mozilla source tree, portions of it are
+capable of being compiled and linked completely independent of Mozilla. You
+may want to do this for testing purposes. The "config" directory contains
+make files that are used for this stand-alone mode. There is even a dumb
+script called "makemake" which can be used to re-create make files, if the
+corresponding Makefile.in files have been changed.
+
+*NOTE* The executable "lterm" requires the NCURSES include file "curses.h"
+
+To create the stand-alone executables, type
+
+ make STAND_ALONE=1 all
+
+(To clean up stand-alone modules, type "make STAND_ALONE=1 clean")
+
+This creates the stand-alone library in "base/lib" and some stand-alone
+executables in the "linetest/lib" directory, in particular, one called 
+"lterm".
+
+The executable "lterm" implements a line terminal (LINETERM), i.e., a
+non-graphical version of XMLterm. In the future, this may be implemented using
+NCURSES for full screen operation. At present, it only provides line-at-a-time
+functionality and is used only for testing.
+
+LINETERM acts as an "engine" for XMLterm, carrying out all the non-graphical
+tasks, completely independent of Mozilla. It is written in C and is licensed
+under both MPL and GPL. It provides functionality similar to the EMACS shell
+mode or the GNU readline package.
+
+LINETERM has various options where trace output may be redirected to a
+different TTY device, for debugging purposes. LINETERM may be used like the
+shell command "sh", e.g.,
+
+  prompt% lterm
+  prompt% ls
+         <listing>
+  prompt% exit
+
+The "tests/escape" program can be used to generate terminal escape sequences
+to test the XMLterm API. In particular, the following command enables
+extensive trace output, if executed within an XMLterm or LINETERM:
+
+  tests/escape 1 98 D

+xmlterm --- A graphical command line interface
+==============================================
+
+An early prototype of XMLterm, an XTERM-like terminal program implemented
+using the open source Mozilla layout engine, is now available to tinker
+with. XMLterm aims to add graphical and hypertext capabilities to the XTERM
+command line interface, while maintaining backwards compatibility.
+
+The basic design philosophy of XMLterm is that the user interface is a dynamic
+XML document. The user and the computer interact by taking turns at appending
+to this XML document. The plain text content of the XML document, i.e.,
+excluding any markup, corresponds to the plain text that would be displayed by
+a plain XTERM. The markup in the XML document is used to add graphical and
+hypertext features. XMLterm uses the Mozilla layout engine to display the XML
+document.
+
+XMLterm is an open source project in its early stages. Comments and
+contributions are welcome!

+ * Meta input refers to input lines that begin with a colon,
+ * or with a "protocol" name followed by a colon, such as
+ * "http: ...".
+ * Meta input lines are not sent to the subordinate process, but simply
+ * echoed as LTERM output through LTERM_READ for further processing.

+ *
+ * If OPCODES == 0, then it means that no data has been read.
+ *
+ * If the returned OPCODES has META and COMPLETION bits set, then the completed
+ * version of the meta input should be supplied through a call to
+ * LTERM_WRITE, with an input data type, as if the user had typed it.
+ *
+ * BUF_ROW and BUF_COL denote the row and starting column at which to

+ * (If character count returned by lterm_read is zero, implying there is no
+ *  data in BUF, then values of BUF_ROW and BUF_COL should be ignored.)
+ * In ScreenMode or LineMode, CURSOR_ROW and CURSOR_COL denote the final

+ *
+ * The bottom left corner of the screen corresponds to row 0, column 0.
+ * BUF_COL, CURSOR_COL are always >= 0, with 0 denoting the leftmost column.

+ * BUF_ROW, CURSOR_ROW are always >=0 when LTERM is in screen mode,
+ * with 0 denoting the bottom row.

+
+We would like to have clean shutdowns of an XMLterm, since we are using
+external resources, e.g., a shell process or an rlogin process. However, the
+XPCOM reference counting can hinder shutdowns, if there cycles.  To avoid
+that, the XMLterm interfaces have a Finalize or Close method. A shutdown
+event triggers a call to the Finalize method of the root interface in the
+"Finalize tree".  When the Finalize method of any interface is called, it
+first calls the Finalize methods of any child nodes in the Finalize tree, then
+releases all the XPCOM references it owns, de-initializes itself and quietly
+waits for its reference count to go to zero. In this "closed" state of the
+interface, any attempts use it result in an error return.
+
+The destructor of an object simply checks if all its interfaces have been
+finalized, and calls the Finalize methods for any that have not been.

+XMLterm installation instructions for Linux binaries
+----------------------------------------------------
+
+*NOTE* This work in progress. User beware!
+
+*NOTE* Check the XMLterm web site <http://xmlterm.org> for updates.
+
+19 Nov 1999
+
+1. First obtain the Mozilla Linux binary tar file
+   ftp://ftp.mozilla.org/pub/mozilla/releases/m11/mozilla-i686-pc-linux-gnu-M11.tar.gz"
+   and untar it in any convenient location. This will create a
+   directory named "package" containing the binaries.
+
+2. Untar the XMLterm binary tar file "xmlterm-i686-pc-linux-gnu-M11.tar.gz"
+   in the "package" directory created above.
+
+3. Type the following command in the "package" directory:
+
+     ./mozilla chrome://xmlterm/content/xmlterm.html
+
+   This should create an XMLTerm in the browser window. Then click on
+   that window with the mouse to shift focus and start typing UNIX
+   commands.
+
+   **NOTE**
+   The command prompt is assumed to be terminated by one of the characters
+   "#$%>?", followed by a space. If this is not the case, many features will
+   not work. This restriction will be relaxed in the future.
+
+4. To use the stand-alone XMLterm executable called "xmlterm",
+   type the following command in the "package" directory:
+
+    ./run-mozilla.sh xmlterm
+
+   (The Mozilla component registry may need to be updated by running the
+    full browser using step 3 at least once before running "xmlterm".)
+
+5. The command line can be edited using EMACS-style key bindings.
+   Command completion should also work with TCSH and BASH, as should history
+   recall.
+
+6. By default, blue coloring is used to indicate clickable display elements.
+   Note that the prompt and the input command line are clickable.
+   (Of course, the appearance of XMLterm is completely configurable
+   using the CSS stylesheet chrome://xmlterm/skin/default/xmlterm.css)
+
+   After typing one or two commands, click on the prompt string of any previous
+   command to see what happens! Then click again on the same prompt string.
+   Also click on "Hide all output" button at the top of the document.
+
+   Clicking on a previous command line (to the right of the prompt) re-executes
+   the command.
+
+7. The sample Perl script "xls", the iconic/hypertext version of the Unix
+   "ls" command, is also installed in the "package" directory. Adding
+   the "package" directory to your path should enable you to use the "xls"
+   command.

+          sell, and offer for sale, and/or otherwise dispose of the
+          Original Code (or portions thereof).
+
+          (c) the licenses granted in this Section 2.1(a) and (b) are
+          effective on the date Initial Developer first distributes
+          Original Code under the terms of this License.
+
+          (d) Notwithstanding Section 2.1(b) above, no patent license
+          is granted: 1) for code that You delete from the Original
+          Code; 2) separate from the Original Code; or 3) for
+          infringements caused by: i) the modification of the Original
+          Code or ii) the combination of the Original Code with other
+          software or devices.
+
+     2.2. Contributor Grant.  Subject to third party intellectual
+     property claims, each Contributor hereby grants You a world-wide,
+     royalty-free, non-exclusive license
+
+          (a) under intellectual property rights (other than patent or
+          trademark) Licensable by Contributor, to use, reproduce,
+          modify, display, perform, sublicense and distribute the
+          Modifications created by such Contributor (or portions
+          thereof) either on an unmodified basis, with other
+          Modifications, as Covered Code and/or as part of a Larger
+          Work; and
+
+          (b) under Patent Claims infringed by the making, using, or
+          selling of Modifications made by that Contributor either
+          alone and/or in combination with its Contributor Version (or
+          portions of such combination), to make, use, sell, offer for
+          sale, have made, and/or otherwise dispose of: 1)
+          Modifications made by that Contributor (or portions
+          thereof); and 2) the combination of Modifications made by
+          that Contributor with its Contributor Version (or portions
+          of such combination).
+
+          (c) the licenses granted in Sections 2.2(a) and 2.2(b) are
+          effective on the date Contributor first makes Commercial Use
+          of the Covered Code.
+
+          (d) Notwithstanding Section 2.2(b) above, no patent license
+	  is granted: 1) for any code that Contributor has deleted from the
+	  Contributor Version; 2) separate from the Contributor Version; 3) for
+	  infringements caused by: i) third party modifications of Contributor
+	  Version or ii) the combination of Modifications made by that
+	  Contributor with other software (except as part of the Contributor
+	  Version) or other devices; or 4) under Patent Claims infringed by
+	  Covered Code in the absence of Modifications made by that Contributor.
+
+3. Distribution Obligations.
+
+     3.1. Application of License.  The Modifications which You create
+     or to which You contribute are governed by the terms of this
+     License, including without limitation Section 2.2. The Source
+     Code version of Covered Code may be distributed only under the
+     terms of this License or a future version of this License
+     released under Section 6.1, and You must include a copy of this
+     License with every copy of the Source Code You distribute. You
+     may not offer or impose any terms on any Source Code version that
+     alters or restricts the applicable version of this License or the
+     recipients' rights hereunder. However, You may include an
+     additional document offering the additional rights described in
+     Section 3.5.
+
+     3.2. Availability of Source Code.  Any Modification which You
+     create or to which You contribute must be made available in
+     Source Code form under the terms of this License either on the
+     same media as an Executable version or via an accepted Electronic
+     Distribution Mechanism to anyone to whom you made an Executable
+     version available; and if made available via Electronic
+     Distribution Mechanism, must remain available for at least twelve
+     (12) months after the date it initially became available, or at
+     least six (6) months after a subsequent version of that
+     particular Modification has been made available to such
+     recipients. You are responsible for ensuring that the Source Code
+     version remains available even if the Electronic Distribution
+     Mechanism is maintained by a third party.
+
+     3.3. Description of Modifications.  You must cause all Covered
+     Code to which You contribute to contain a file documenting the
+     changes You made to create that Covered Code and the date of any
+     change. You must include a prominent statement that the
+     Modification is derived, directly or indirectly, from Original
+     Code provided by the Initial Developer and including the name of
+     the Initial Developer in (a) the Source Code, and (b) in any
+     notice in an Executable version or related documentation in which
+     You describe the origin or ownership of the Covered Code.
+
+     3.4. Intellectual Property Matters (a) Third Party Claims.  If
+          Contributor has knowledge that a license under a third
+          party's intellectual property rights is required to exercise
+          the rights granted by such Contributor under Sections 2.1 or
+          2.2, Contributor must include a text file with the Source
+          Code distribution titled "LEGAL'' which describes the claim
+          and the party making the claim in sufficient detail that a
+          recipient will know whom to contact. If Contributor obtains
+          such knowledge after the Modification is made available as
+          described in Section 3.2, Contributor shall promptly modify
+          the LEGAL file in all copies Contributor makes available
+          thereafter and shall take other steps (such as notifying
+          appropriate mailing lists or newsgroups) reasonably
+          calculated to inform those who received the Covered Code
+          that new knowledge has been obtained.
+
+          (b) Contributor APIs.  If Contributor's Modifications
+          include an application programming interface and Contributor
+          has knowledge of patent licenses which are reasonably
+          necessary to implement that API, Contributor must also
+          include this information in the LEGAL file.
+
+               (c) Representations.  Contributor represents that,
+          except as disclosed pursuant to Section 3.4(a) above,
+          Contributor believes that Contributor's Modifications are
+          Contributor's original creation(s) and/or Contributor has
+          sufficient rights to grant the rights conveyed by this
+          License.
+
+     3.5. Required Notices.  You must duplicate the notice in Exhibit
+     A in each file of the Source Code.  If it is not possible to put
+     such notice in a particular Source Code file due to its
+     structure, then You must include such notice in a location (such
+     as a relevant directory) where a user would be likely to look for
+     such a notice.  If You created one or more Modification(s) You
+     may add your name as a Contributor to the notice described in
+     Exhibit A.  You must also duplicate this License in any
+     documentation for the Source Code where You describe recipients'
+     rights or ownership rights relating to Covered Code.  You may
+     choose to offer, and to charge a fee for, warranty, support,
+     indemnity or liability obligations to one or more recipients of
+     Covered Code.  However, You may do so only on Your own behalf,
+     and not on behalf of the Initial Developer or any
+     Contributor. You must make it absolutely clear than any such
+     warranty, support, indemnity or liability obligation is offered
+     by You alone, and You hereby agree to indemnify the Initial
+     Developer and every Contributor for any liability incurred by the
+     Initial Developer or such Contributor as a result of warranty,
+     support, indemnity or liability terms You offer.
+
+     3.6. Distribution of Executable Versions.  You may distribute
+     Covered Code in Executable form only if the requirements of
+     Section 3.1-3.5 have been met for that Covered Code, and if You
+     include a notice stating that the Source Code version of the
+     Covered Code is available under the terms of this License,
+     including a description of how and where You have fulfilled the
+     obligations of Section 3.2. The notice must be conspicuously
+     included in any notice in an Executable version, related
+     documentation or collateral in which You describe recipients'
+     rights relating to the Covered Code. You may distribute the
+     Executable version of Covered Code or ownership rights under a
+     license of Your choice, which may contain terms different from
+     this License, provided that You are in compliance with the terms
+     of this License and that the license for the Executable version
+     does not attempt to limit or alter the recipient's rights in the
+     Source Code version from the rights set forth in this License. If
+     You distribute the Executable version under a different license
+     You must make it absolutely clear that any terms which differ
+     from this License are offered by You alone, not by the Initial
+     Developer or any Contributor. You hereby agree to indemnify the
+     Initial Developer and every Contributor for any liability
+     incurred by the Initial Developer or such Contributor as a result
+     of any such terms You offer.
+
+     3.7. Larger Works.  You may create a Larger Work by combining
+     Covered Code with other code not governed by the terms of this
+     License and distribute the Larger Work as a single product. In
+     such a case, You must make sure the requirements of this License
+     are fulfilled for the Covered Code.
+
+4. Inability to Comply Due to Statute or Regulation.
+
+     If it is impossible for You to comply with any of the terms of
+     this License with respect to some or all of the Covered Code due
+     to statute, judicial order, or regulation then You must: (a)
+     comply with the terms of this License to the maximum extent
+     possible; and (b) describe the limitations and the code they
+     affect. Such description must be included in the LEGAL file
+     described in Section 3.4 and must be included with all
+     distributions of the Source Code.  Except to the extent
+     prohibited by statute or regulation, such description must be
+     sufficiently detailed for a recipient of ordinary skill to be
+     able to understand it.
+
+5. Application of this License.
+
+     This License applies to code to which the Initial Developer has
+     attached the notice in Exhibit A and to related Covered Code.
+
+6. Versions of the License.
+
+     6.1. New Versions.  Netscape Communications Corporation
+     (''Netscape'') may publish revised and/or new versions of the
+     License from time to time. Each version will be given a
+     distinguishing version number.
+
+     6.2. Effect of New Versions.  Once Covered Code has been
+     published under a particular version of the License, You may
+     always continue to use it under the terms of that version. You
+     may also choose to use such Covered Code under the terms of any
+     subsequent version of the License published by Netscape. No one
+     other than Netscape has the right to modify the terms applicable
+     to Covered Code created under this License.
+
+     6.3. Derivative Works.  If You create or use a modified version
+     of this License (which you may only do in order to apply it to
+     code which is not already Covered Code governed by this License),
+     You must (a) rename Your license so that the phrases ''Mozilla'',
+     ''MOZILLAPL'', ''MOZPL'', ''Netscape'', "MPL", ''NPL'' or any
+     confusingly similar phrase do not appear in your license (except
+     to note that your license differs from this License) and (b)
+     otherwise make it clear that Your version of the license contains
+     terms which differ from the Mozilla Public License and Netscape
+     Public License.  (Filling in the name of the Initial Developer,
+     Original Code or Contributor in the notice described in Exhibit A
+     shall not of themselves be deemed to be modifications of this
+     License.)
+
+7. DISCLAIMER OF WARRANTY.
+
+     COVERED CODE IS PROVIDED UNDER THIS LICENSE ON AN "AS IS'' BASIS,
+     WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED,
+     INCLUDING, WITHOUT LIMITATION, WARRANTIES THAT THE COVERED CODE
+     IS FREE OF DEFECTS, MERCHANTABLE, FIT FOR A PARTICULAR PURPOSE OR
+     NON-INFRINGING. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE
+     OF THE COVERED CODE IS WITH YOU. SHOULD ANY COVERED CODE PROVE
+     DEFECTIVE IN ANY RESPECT, YOU (NOT THE INITIAL DEVELOPER OR ANY
+     OTHER CONTRIBUTOR) ASSUME THE COST OF ANY NECESSARY SERVICING,
+     REPAIR OR CORRECTION. THIS DISCLAIMER OF WARRANTY CONSTITUTES AN
+     ESSENTIAL PART OF THIS LICENSE. NO USE OF ANY COVERED CODE IS
+     AUTHORIZED HEREUNDER EXCEPT UNDER THIS DISCLAIMER.
+
+8. TERMINATION.
+
+     8.1.  This License and the rights granted hereunder will
+     terminate automatically if You fail to comply with terms herein
+     and fail to cure such breach within 30 days of becoming aware of
+     the breach. All sublicenses to the Covered Code which are
+     properly granted shall survive any termination of this
+     License. Provisions which, by their nature, must remain in effect
+     beyond the termination of this License shall survive.
+
+     8.2.  If You initiate litigation by asserting a patent
+     infringement claim (excluding declatory judgment actions) against
+     Initial Developer or a Contributor (the Initial Developer or
+     Contributor against whom You file such action is referred to as
+     "Participant") alleging that:
+
+     (a) such Participant's Contributor Version directly or indirectly
+     infringes any patent, then any and all rights granted by such
+     Participant to You under Sections 2.1 and/or 2.2 of this License
+     shall, upon 60 days notice from Participant terminate
+     prospectively, unless if within 60 days after receipt of notice
+     You either: (i) agree in writing to pay Participant a mutually
+     agreeable reasonable royalty for Your past and future use of
+     Modifications made by such Participant, or (ii) withdraw Your
+     litigation claim with respect to the Contributor Version against
+     such Participant.  If within 60 days of notice, a reasonable
+     royalty and payment arrangement are not mutually agreed upon in
+     writing by the parties or the litigation claim is not withdrawn,
+     the rights granted by Participant to You under Sections 2.1
+     and/or 2.2 automatically terminate at the expiration of the 60
+     day notice period specified above.
+
+     (b) any software, hardware, or device, other than such
+     Participant's Contributor Version, directly or indirectly
+     infringes any patent, then any rights granted to You by such
+     Participant under Sections 2.1(b) and 2.2(b) are revoked
+     effective as of the date You first made, used, sold, distributed,
+     or had made, Modifications made by that Participant.
+
+     8.3.  If You assert a patent infringement claim against
+     Participant alleging that such Participant's Contributor Version
+     directly or indirectly infringes any patent where such claim is
+     resolved (such as by license or settlement) prior to the
+     initiation of patent infringement litigation, then the reasonable
+     value of the licenses granted by such Participant under Sections
+     2.1 or 2.2 shall be taken into account in determining the amount
+     or value of any payment or license.
+
+     8.4.  In the event of termination under Sections 8.1 or 8.2
+     above, all end user license agreements (excluding distributors
+     and resellers) which have been validly granted by You or any
+     distributor hereunder prior to termination shall survive
+     termination.
+
+9. LIMITATION OF LIABILITY.
+
+     UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY, WHETHER TORT
+     (INCLUDING NEGLIGENCE), CONTRACT, OR OTHERWISE, SHALL YOU, THE
+     INITIAL DEVELOPER, ANY OTHER CONTRIBUTOR, OR ANY DISTRIBUTOR OF
+     COVERED CODE, OR ANY SUPPLIER OF ANY OF SUCH PARTIES, BE LIABLE
+     TO ANY PERSON FOR ANY INDIRECT, SPECIAL, INCIDENTAL, OR
+     CONSEQUENTIAL DAMAGES OF ANY CHARACTER INCLUDING, WITHOUT
+     LIMITATION, DAMAGES FOR LOSS OF GOODWILL, WORK STOPPAGE, COMPUTER
+     FAILURE OR MALFUNCTION, OR ANY AND ALL OTHER COMMERCIAL DAMAGES
+     OR LOSSES, EVEN IF SUCH PARTY SHALL HAVE BEEN INFORMED OF THE
+     POSSIBILITY OF SUCH DAMAGES. THIS LIMITATION OF LIABILITY SHALL
+     NOT APPLY TO LIABILITY FOR DEATH OR PERSONAL INJURY RESULTING
+     FROM SUCH PARTY'S NEGLIGENCE TO THE EXTENT APPLICABLE LAW
+     PROHIBITS SUCH LIMITATION. SOME JURISDICTIONS DO NOT ALLOW THE
+     EXCLUSION OR LIMITATION OF INCIDENTAL OR CONSEQUENTIAL DAMAGES,
+     SO THIS EXCLUSION AND LIMITATION MAY NOT APPLY TO YOU.
+
+10. U.S. GOVERNMENT END USERS.
+
+     The Covered Code is a ''commercial item,'' as that term is
+     defined in 48 C.F.R. 2.101 (Oct. 1995), consisting of
+     ''commercial computer software'' and ''commercial computer
+     software documentation,'' as such terms are used in 48
+     C.F.R. 12.212 (Sept. 1995).  Consistent with 48 C.F.R. 12.212 and
+     48 C.F.R. 227.7202-1 through 227.7202-4 (June 1995), all
+     U.S. Government End Users acquire Covered Code with only those
+     rights set forth herein.
+
+11. MISCELLANEOUS.
+
+     This License represents the complete agreement concerning subject
+     matter hereof. If any provision of this License is held to be
+     unenforceable, such provision shall be reformed only to the
+     extent necessary to make it enforceable.  This License shall be
+     governed by California law provisions (except to the extent
+     applicable law, if any, provides otherwise), excluding its
+     conflict-of-law provisions. With respect to disputes in which at
+     least one party is a citizen of, or an entity chartered or
+     registered to do business in the United States of America, any
+     litigation relating to this License shall be subject to the
+     jurisdiction of the Federal Courts of the Northern District of
+     California, with venue lying in Santa Clara County, California,
+     with the losing party responsible for costs, including without
+     limitation, court costs and reasonable attorneys' fees and
+     expenses. The application of the United Nations Convention on
+     Contracts for the International Sale of Goods is expressly
+     excluded. Any law or regulation which provides that the language
+     of a contract shall be construed against the drafter shall not
+     apply to this License.
+
+12. RESPONSIBILITY FOR CLAIMS.
+
+     As between Initial Developer and the Contributors, each party is
+     responsible for claims and damages arising, directly or
+     indirectly, out of its utilization of rights under this License
+     and You agree to work with Initial Developer and Contributors to
+     distribute such responsibility on an equitable basis.  Nothing
+     herein is intended or shall be deemed to constitute any admission
+     of liability.
+
+13. MULTIPLE-LICENSED CODE.
+
+     Initial Developer may designate portions of the Covered Code as
+     ?Multiple-Licensed?.  ?Multiple-Licensed? means that the Initial
+     Developer permits you to utilize portions of the Covered Code
+     under Your choice of the NPL or the alternative licenses, if any,
+     specified by the Initial Developer in the file described in
+     Exhibit A.
+
+EXHIBIT A -Mozilla Public License.

+
+     AMENDMENTS
+
+     The Netscape Public License Version 1.1 ("NPL") consists of the
+     Mozilla Public License Version 1.1 with the following Amendments,
+     including Exhibit A-Netscape Public License.  Files identified
+     with "Exhibit A-Netscape Public License" are governed by the
+     Netscape Public License Version 1.1.
+
+     Additional Terms applicable to the Netscape Public License.
+     I. Effect.  These additional terms described in this Netscape
+     Public License -- Amendments shall apply to the Mozilla
+     Communicator client code and to all Covered Code under this
+     License.
+
+          II. ''Netscape's Branded Code'' means Covered Code that
+          Netscape distributes and/or permits others to distribute
+          under one or more trademark(s) which are controlled by
+          Netscape but which are not licensed for use under this
+          License.
+
+          III. Netscape and logo.  This License does not grant any
+          rights to use the trademarks "Netscape'', the "Netscape N
+          and horizon'' logo or the "Netscape lighthouse" logo,
+          "Netcenter", "Gecko", "Java" or "JavaScript", "Smart
+          Browsing" even if such marks are included in the Original
+          Code or Modifications.
+
+          IV. Inability to Comply Due to Contractual Obligation.
+          Prior to licensing the Original Code under this License,
+          Netscape has licensed third party code for use in Netscape's
+          Branded Code. To the extent that Netscape is limited
+          contractually from making such third party code available
+          under this License, Netscape may choose to reintegrate such
+          code into Covered Code without being required to distribute
+          such code in Source Code form, even if such code would
+          otherwise be considered ''Modifications'' under this
+          License.
+
+          V. Use of Modifications and Covered Code by Initial
+          Developer.  V.1. In General.  The obligations of Section 3
+          apply to Netscape, except to the extent specified in this
+          Amendment, Section V.2 and V.3.
+
+               V.2. Other Products.  Netscape may include Covered Code
+               in products other than the Netscape's Branded Code
+               which are released by Netscape during the two (2) years
+               following the release date of the Original Code,
+               without such additional products becoming subject to
+               the terms of this License, and may license such
+               additional products on different terms from those
+               contained in this License.
+
+               V.3. Alternative Licensing.  Netscape may license the
+               Source Code of Netscape's Branded Code, including
+               Modifications incorporated therein, without such
+               Netscape Branded Code becoming subject to the terms of
+               this License, and may license such Netscape Branded
+               Code on different terms from those contained in this
+               License.
+
+          VI. Litigation.  Notwithstanding the limitations of Section
+          11 above, the provisions regarding litigation in Section
+          11(a), (b) and (c) of the License shall apply to all
+          disputes relating to this License.

+Portability issues
+---------------------
+
+16 Sep 1999
+
+Much of the XMLterm code is cross-platform. Implementation features that 
+affect portability at the moment are:
+
+1. Main event handling:
+     By default, the present implementation of XMLterm directly uses a GTK
+     call to set up a handler for XMLterm output events. This can be disabled
+     by setting NO_CALLBACK=1 in the make command line, and calling the
+     method mozIXMLTermShell::Poll() frequently to poll for readable output
+     from LineTerm.
+     (A better event/callback mechanism needs to be implemented.)
+
+2. pseudo-TTY (PTY) operations:
+     The PTY interface for XMLterm is currently implemented only for
+     two platforms, Linux and Solaris. At some point, the PTY interface
+     should be ported to most Unix platforms. On platforms where PTY
+     operations are not implemented, the cross-platform NSPR process mechanism
+     is used to create a "slave" process. However, this process uses NSPR
+     pipes for communication, which prevents the use of terminal control
+     characters such as the most usefule Control-C. (Is there a way around
+     this restriction?)
+
+  What about Windows? It should be possible to use XMLterm even under Windows,
+  using the NSPR process/pipe functions for communication and
+  using the Cygwin utilities to simulate the Unix environment.
+
+3. The lightweight GeckoTerm uses GTK.
+
+4. The "unistring" module uses wchar functions which do not always have
+   the same names.

+
+Appending each output line separately, separated by <BR> elements, to a
+displayed HTML document seems to be rather slow. See the file
+base/mozXMLTermSession.cpp
+
+As a workaround, multiple output lines are batched into a single <PRE>
+element. This will basically only work for plain text output, without markup.
+To disable this workaround and expose the "bug", create the XMLterm libraries
+as described in the INSTALL file. Then execute the following to make the
+"buggy" libraries:
+
+cd base
+rm mozXMLTermSession.o
+make NO_WORKAROUND=1 mozXMLTermSession.o
+make libs
+
+(If you are using the "gterm" executable, you will need to re-make it as
+well)
+
+Now execute any command which produces several lines of output in an
+XMLterm window.

-# repackage.sh -- Repackage NSPR from /s/b/c to mozilla.org format
-#
-# syntax: repackage.sh
-#
-# Description:
-# repackage.sh creates NSPR binary distributions for mozilla.org from
-# the internal binary distributions in /share/builds/components/nspr20.
-# There are reasons why we can't just push the internal binary distributions
-# to mozilla.org. External developers prefer to use the common archive 
-# file format for their platforms, rather than the jar files we use internally.
-#
-# On Unix, we create a tar.gz file.  On Windows, we create a zip file.
-# For example: NSPR 4.1.1, these would be nspr-4.1.1.tar.gz and nspr-4.1.1.zip.
-#
-# When unpacked, nspr-4.1.1.tar.gz or nspr-4.1.1.zip should expand to a
-# nspr-4.1.1 directory that contains three subdirectories: include, lib,
-# and bin.  The header files, with the correct line endings for the
-# platform, are in nspr-4.1.1/include.  The libraries are in nspr-4.1.1/lib.
-# The executable programs are in nspr-4.1.1/bin.
-# 
-# Note! Files written with Gnu tar are not readable by some non-Gnu
-# versions. Sun, in particular.
-# 
-# 
-# 
-# 
-# ------------------------------------------------------------------
-#
-# These variables should be modified for each NSPR release.
