+  This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+  0. Additional Definitions.
+
+  As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+  "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+  An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+  A "Combined Work" is a work produced by combining or linking an
+Application with the Library.  The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+  The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+  The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+  1. Exception to Section 3 of the GNU GPL.
+
+  You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+  2. Conveying Modified Versions.
+
+  If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+   a) under this License, provided that you make a good faith effort to
+   ensure that, in the event an Application does not supply the
+   function or data, the facility still operates, and performs
+   whatever part of its purpose remains meaningful, or
+
+   b) under the GNU GPL, with none of the additional permissions of
+   this License applicable to that copy.
+
+  3. Object Code Incorporating Material from Library Header Files.
+
+  The object code form of an Application may incorporate material from
+a header file that is part of the Library.  You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+   a) Give prominent notice with each copy of the object code that the
+   Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the object code with a copy of the GNU GPL and this license
+   document.
+
+  4. Combined Works.
+
+  You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+   a) Give prominent notice with each copy of the Combined Work that
+   the Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the Combined Work with a copy of the GNU GPL and this license
+   document.
+
+   c) For a Combined Work that displays copyright notices during
+   execution, include the copyright notice for the Library among
+   these notices, as well as a reference directing the user to the
+   copies of the GNU GPL and this license document.
+
+   d) Do one of the following:
+
+       0) Convey the Minimal Corresponding Source under the terms of this
+       License, and the Corresponding Application Code in a form
+       suitable for, and under terms that permit, the user to
+       recombine or relink the Application with a modified version of
+       the Linked Version to produce a modified Combined Work, in the
+       manner specified by section 6 of the GNU GPL for conveying
+       Corresponding Source.
+
+       1) Use a suitable shared library mechanism for linking with the
+       Library.  A suitable mechanism is one that (a) uses at run time
+       a copy of the Library already present on the user's computer
+       system, and (b) will operate properly with a modified version
+       of the Library that is interface-compatible with the Linked
+       Version.
+
+   e) Provide Installation Information, but only if you would otherwise
+   be required to provide such information under section 6 of the
+   GNU GPL, and only to the extent that such information is
+   necessary to install and execute a modified version of the
+   Combined Work produced by recombining or relinking the
+   Application with a modified version of the Linked Version. (If
+   you use option 4d0, the Installation Information must accompany
+   the Minimal Corresponding Source and Corresponding Application
+   Code. If you use option 4d1, you must provide the Installation
+   Information in the manner specified by section 6 of the GNU GPL
+   for conveying Corresponding Source.)
+
+  5. Combined Libraries.
+
+  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 that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+   a) Accompany the combined library with a copy of the same work based
+   on the Library, uncombined with any other library facilities,
+   conveyed under the terms of this License.
+
+   b) Give prominent notice with the combined library that part of it
+   is a work based on the Library, and explaining where to find the
+   accompanying uncombined form of the same work.
+
+  6. Revised Versions of the GNU Lesser General Public License.
+
+  The Free Software Foundation may publish revised and/or new versions
+of the GNU 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 as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+  If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.

 This file contains a brief description of new features which have been added to Smarty 3.1
 
+Smarty 3.1.31
+    New tags for inheritance parent and child
+    =========================================
+    {block_parent}  == {$smarty.block.parent}
+    {block_child}  == {$smarty.block.child}
+
+Smarty 3.1.30
+
+    Loop optimization {foreach} and {section}
+    =========================================
+    Smarty does optimize the {foreach} and {section} loops by removing code for not needed loop
+    properties.
+    The compiler collects needed properties by scanning the current template for $item@property,
+    $smarty.foreach.name.property and $smarty.section.name.property.
+    The compiler does not know if additional properties will be needed outside the current template scope.
+    Additional properties can be generated by adding them with the property attribute.
+
+    Example:
+        index.tpl
+        {foreach $from as $item properties=[iteration, index]}
+            {include 'sub.tpl'}
+            {$item.total}
+        {/foreach}
+
+        sub.tpl
+        {$item.index} {$item.iteration} {$item.total}
+
+    In above example code for the 'total' property is automatically generated as $item.total is used in
+    index.tpl. Code for 'iteration' and 'index' must be added with properties=[iteration, index].
+
+    New tag {make_nocache}
+    ======================
+    Syntax: {make_nocache $foo}
+
+    This tag makes a variable which does exists normally only while rendering the compiled template
+    available in the cached template for use in not cached expressions.
+
+    Expample:
+        {foreach from=$list item=item}
+            <li>{$item.name} {make_nocache $item}{if $current==$item.id} ACTIVE{/if}</li>
+        {/foreach}
+
+    The {foreach} loop is rendered while processing the compiled template, but $current is a nocache
+    variable. Normally the {if $current==$item.id} would fail as the $item variable is unkown in the 
+    cached template. {make_nocache $item} does make the current $item value known in thee cached template.
+
+    {make_nocache} is ignored when caching is disabled or the variable does exists as nocache variable.
+
+    NOTE: if the variable value does contain objects these must have the __set_state method implemented.
+
+
+    Scope Attributes
+    ================
+    The scope handling has been updated to cover all cases of variable assignments in templates.
+
+    The tags {assign}, {append} direct assignments like {$foo = ...}, {$foo[...]= ...} support
+    the following optional scope attributes:
+    scope='parent'    - the variable will be assigned in the current template and if the template
+                        was included by {include} the calling template
+    scope='tpl_root'  - the variable will be assigned in the outermost root template called by $smarty->display()
+                        or $smarty->fetch() and is bubbled up all {include} sub-templates to the current template.
+    scope='smarty'    - the variable will be assigned in the Smarty object and is bubbled up all {include} sub-templates
+                        to the current template.
+    scope='global'    - the variable will be assigned as Smarty object global variable and is bubbled up all {include}
+                        sub-templates to the current template.
+    scope='root'      - the variable will be assigned if a data object was used for variable definitions in the data
+                        object or in the Smarty object otherwise and is bubbled up all {include} sub-templates to the
+                        current template.
+    scope='local'     - this scope has only a meaning if the tag is called within a template {function}.
+                        The variable will be assigned in the local scope of the template function and the
+                        template which did call the template function.
+
+
+    The {config_load} tag supports all of the above except the global scope.
+
+    The scope attribute can be used also with the {include} tag.
+    Supported scope are parent, tpl_root, smarty, global and root.
+    A scope used together with the {include} tag will cause that with some exceptions any variable
+    assignment within that sub-template will update/assign the variable in other scopes according
+    to the above rules. It does include also variables assigned by plugins, tags supporting the assign=foo 
+    attribute and direct assignments in {if} and {while} like {if $foo=$bar}.
+    Excluded are the key and value variables of {foreach}, {for} loop variables , variables passed by attributes
+    in {include} and direct increments/decrements like {$foo++}, {$foo--}
+
+    Note: The scopes should be used only to the extend really need. If a variable value assigned in an included
+          sub-template should be returned to the calling sub-template just use {$foo='bar' scope='parent'}.
+          Use scopes only with variables for which it's realy needed. Avoid general scope settings with the
+          {include} tag as it can have a performance impact.
+
+     The {assign}, {append}, {config_load} and {$foo...=...} tags have a new option flag 'noscope'.Thi
+     Example: {$foo='bar' noscope}  This will assign $foo only in the current template and any scope settings
+               at {include} is ignored.
+
+
+    Caching
+    =======
+    Caching does now observe the template_dir setting and will create separate cache files if required
+
+    Compiled Templates
+    ==================
+    The template_dir setting is now encoded in the uid of the file name.
+    The content of the compiled template may depend on the template_dir search order
+    {include .... inline} is used or $smarty->merge_compiled_includes is enabled
+
+    APC
+    ===
+    If APC is enabled force an apc_compile_file() when compiled or cached template was updated
