+#
+# This configuration table allows to customize the

+#
+# The syntax is that each entry has the form :

+#   "key" Keyname { ("+"|"-") Modename } ":" (String|Operation)
+#
+# Keynames are those defined in <qnamespace.h> with the
+# "Qt::Key_" removed. (We'd better insert the list here)
+#
+# Mode names are : 
+#
+# - Shift
+# - Alt
+# - Control
+#
+#   The VT100 emulation has two modes that can affect the
+#   sequences emitted by certain keys. These modes are
+#   under control of the client program.
+#   
+# - Newline     : effects Return and Enter key.
+# - Application : effects Up and Down key.
+#
+# - Ansi        : effects Up and Down key (This is for VT52, really).
+#
+# Operations are
+#
+# - scrollUpLine
+# - scrollUpPage
+# - scrollDownLine
+# - scrollDownPage
+#
+# - emitSelection
+#
+# If the key is not found here, the text of the

+# [vt420pc.keytab] Konsole Keyboard Table (VT420pc keys)
+# adapted by ferdinand gassauer f.gassauer@aon.at
+# Nov 2000
+#
+################################################################
+#
+# The escape sequences emmited by the 
+# keys Shift+F1 to Shift+F12 might not fit your needs
+#
+################# IMPORTANT NOTICE #############################
+# the key bindings (Kcontrol -> look and feel -> keybindgs) 
+# overrule the settings in this file. The key bindings might be 
+# changed by the user WITHOUT notification of the maintainer of
+# the keytab file. Konsole will not work as expected by 
+# the maintainer of the keytab file.

+
+keyboard "DEC VT420 Terminal"
+
+# --------------------------------------------------------------
+#
+# This configuration table allows to customize the
+# meaning of the keys.
+#
+# The syntax is that each entry has the form : 
+#
+#   "key" Keyname { ("+"|"-") Modename } ":" (String|Operation)
+#
+# Keynames are those defined in <qnamespace.h> with the
+# "Qt::Key_" removed. (We'd better insert the list here)
+#
+# Mode names are : 
+#
+# - Shift
+# - Alt
+# - Control
+#
+#   The VT100 emulation has two modes that can affect the
+#   sequences emitted by certain keys. These modes are
+#   under control of the client program.
+#   
+# - Newline     : effects Return and Enter key.
+# - Application : effects Up and Down key.
+#
+# - Ansi        : effects Up and Down key (This is for VT52, really).
+#
+# Operations are
+#
+# - scrollUpLine
+# - scrollUpPage
+# - scrollDownLine
+# - scrollDownPage
+#
+# - emitSelection
+#
+# If the key is not found here, the text of the
+# key event as provided by QT is emitted, possibly
+# preceeded by ESC if the Alt key is pressed.

+
+The Crystal Project are released under LGPL. GNU General Public License.
+
+This License Agreement applies to any software library or other program
+which contains a notice placed by the copyright holder or other
+authorized party saying it may be distributed under the terms of this
+Lesser General Public License (also called "this License"). Each
+licensee is addressed as "you".
+
+A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+The "Library", below, refers to any such software library or work which
+has been distributed under these terms. A "work based on the Library"
+means either the Library or any derivative work under copyright law:
+that is to say, a work containing the Library or a portion of it, either
+verbatim or with modifications and/or translated straightforwardly into
+another language. (Hereinafter, translation is included without
+limitation in the term "modification".)
+
+"Source code" for a work means the preferred form of the work for making
+modifications to it. For a library, 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 library.
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of running
+a program using the Library is not restricted, and output from such a
+program is covered only if its contents constitute a work based on the
+Library (independent of the use of the Library in a tool for writing
+it). Whether that is true depends on what the Library does and what the
+program that uses the Library does.
+
+You may copy and distribute verbatim copies of the Library's complete
+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
+distribute a copy of this License along with the Library.
+
+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.
+
+You may modify your copy or copies of the Library or any portion of it,
+thus forming a work based on the Library, and copy and distribute such
+modifications or work under the terms of Section 1 above, provided that
+you also meet all of these conditions:
+
+The modified work must itself be a software library. You must cause the
+files modified to carry prominent notices stating that you changed the
+files and the date of any change. You must cause the whole of the work
+to be licensed at no charge to all third parties under the terms of this
+License. If a facility in the modified Library refers to a function or a
+table of data to be supplied by an application program that uses the
+facility, other than as an argument passed when the facility is invoked,
+then you must make a good faith effort to ensure that, in the event an
+application does not supply such function or table, the facility still
+operates, and performs whatever part of its purpose remains meaningful.
+(For example, a function in a library to compute square roots has a
+purpose that is entirely well-defined independent of the application.
+Therefore, Subsection 2d requires that any application-supplied function
+or table used by this function must be optional: if the application does
+not supply it, the square root function must still compute square
+roots.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Library, 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 Library, 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 Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of a
+storage or distribution medium does not bring the other work under the
+scope of this License.
+
+You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library. To do
+this, you must alter all the notices that refer to this License, so that
+they refer to the ordinary GNU General Public License, version 2,
+instead of to this License. (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.) Do not make any other change in these
+notices.
+
+Once this change is made in a given copy, it is irreversible for that
+copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+This option is useful when you wish to copy part of the code of the
+Library into a program that is not a library.
+
+You may copy and distribute the Library (or a portion or derivative of
+it, under Section 2) in object code or executable form under the terms
+of Sections 1 and 2 above provided that you 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.
+
+If distribution of 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 satisfies the requirement to distribute the
+source code, even though third parties are not compelled to copy the
+source along with the object code.
+
+A program that contains no derivative of any portion of the Library, but
+is designed to work with the Library by being compiled or linked with
+it, is called a "work that uses the Library". Such a work, in isolation,
+is not a derivative work of the Library, and therefore falls outside the
+scope of this License.
+
+However, linking a "work that uses the Library" with the Library creates
+an executable that is a derivative of the Library (because it contains
+portions of the Library), rather than a "work that uses the library".
+The executable is therefore covered by this License. Section 6 states
+terms for distribution of such executables. When a "work that uses the
+Library" uses material from a header file that is part of the Library,
+the object code for the work may be a derivative work of the Library
+even though the source code is not. Whether this is true is especially
+significant if the work can be linked without the Library, or if the
+work is itself a library. The threshold for this to be true is not
+precisely defined by law.
+
+If such an object file uses only numerical parameters, data structure
+layouts and accessors, and small macros and small inline functions (ten
+lines or less in length), then the use of the object file is
+unrestricted, regardless of whether it is legally a derivative work.
+(Executables containing this object code plus portions of the Library
+will still fall under Section 6.)
+
+Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6, whether
+or not they are linked directly with the Library itself.
+
+As an exception to the Sections above, you may also combine or link a
+"work that uses the Library" with the Library to produce a work
+containing portions of the Library, and distribute that work under terms
+of your choice, provided that the terms permit modification of the work
+for the customer's own use and reverse engineering for debugging such
+modifications.
+
+You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License. You must supply a copy of this License. If the work during
+execution displays copyright notices, you must include the copyright
+notice for the Library among them, as well as a reference directing the
+user to the copy of this License. Also, you must do one of these things:
+
+Accompany the work with the complete corresponding machine-readable
+source code for the Library including whatever changes were used in the
+work (which must be distributed under Sections 1 and 2 above); and, if
+the work is an executable linked with the Library, with the complete
+machine-readable "work that uses the Library", as object code and/or
+source code, so that the user can modify the Library and then relink to
+produce a modified executable containing the modified Library. (It is
+understood that the user who changes the contents of definitions files
+in the Library will not necessarily be able to recompile the application
+to use the modified definitions.) . Use a suitable shared library
+mechanism for linking with the Library. A suitable mechanism is one that
+(1) uses at run time a copy of the library already present on the user's
+computer system, rather than copying library functions into the
+executable, and (2) will operate properly with a modified version of the
+library, if the user installs one, as long as the modified version is
+interface-compatible with the version that the work was made with.
+Accompany the work with a written offer, valid for at least three years,
+to give the same user the materials specified in Subsection 6a, above,
+for a charge no more than the cost of performing this distribution. If
+distribution of the work is made by offering access to copy from a
+designated place, offer equivalent access to copy the above specified
+materials from the same place. Verify that the user has already received
+a copy of these materials or that you have already sent this user a
+copy. For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it. However, as a special exception, the
+materials to be 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.
+
+It may happen that this requirement contradicts the license restrictions
+of other proprietary libraries that do not normally accompany the
+operating system. Such a contradiction means you cannot use both them
+and the Library together in an executable that you distribute.
+
+You may place library facilities that are a work based on the Library
+side-by-side in a single library together with other library facilities
+not covered by this License, and distribute such a combined library,
+provided that the separate distribution of the work based on the Library
+and of the other library facilities is otherwise permitted, and provided
+that you do these two things:
+
+Accompany the combined library with a copy of the same work based on the
+Library, uncombined with any other library facilities. This must be
+distributed under the terms of the Sections above.
+
+Give prominent notice with the combined library of the fact that part of
+it is a work based on the Library, and explaining where to find the
+accompanying uncombined form of the same work.
+
+You may not copy, modify, sublicense, link with, or distribute the
+Library except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense, link with, or distribute the
+Library 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.
+
+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 Library or its derivative works. These actions are prohibited by law
+if you do not accept this License. Therefore, by modifying or
+distributing the Library (or any work based on the Library), you
+indicate your acceptance of this License to do so, and all its terms and
+conditions for copying, distributing or modifying the Library or works
+based on it.
+
+Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+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 with
+this License.
+
+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 Library at all. For example, if a patent license would
+not permit royalty-free redistribution of the Library 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 Library.
+
+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.
+
+If the distribution and/or use of the Library is restricted in certain
+countries either by patents or by copyrighted interfaces, the original
+copyright holder who places the Library 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.
+
+The Free Software Foundation may publish revised and/or new versions of
+the Lesser 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 Library
+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 Library does not specify a license
+version number, you may choose any version ever published by the Free
+Software Foundation.
+
+If you wish to incorporate parts of the Library into other free programs
+whose distribution conditions are incompatible with these, 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
+
+Because the library is licensed free of charge, there is no warranty for
+the library, to the extent permitted by applicable law. Except when
+otherwise stated in writing the copyright holders and/or other parties
+provide the library "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 library is with
+you. Should the library prove defective, you assume the cost of all
+necessary servicing, repair or correction.
+
+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 library 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 library
+(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 library to operate with any other software), even if such holder or
+other party has been advised of the possibility of such damages.
