+"""Add a new slide to an unpacked PPTX directory.
+
+Usage: python add_slide.py <unpacked_dir> <source>
+
+The source can be:
+  - A slide file (e.g., slide2.xml) - duplicates the slide
+  - A layout file (e.g., slideLayout2.xml) - creates from layout
+
+Examples:
+    python add_slide.py unpacked/ slide2.xml
+    # Duplicates slide2, creates slide5.xml
+
+    python add_slide.py unpacked/ slideLayout2.xml
+    # Creates slide5.xml from slideLayout2.xml
+
+To see available layouts: ls unpacked/ppt/slideLayouts/
+
+Prints the <p:sldId> element to add to presentation.xml.

+
+    Note that local names in this namespace are intended to be defined

+    following names are currently defined in this namespace and should
+    not be used with conflicting semantics by any Working Group,
+    specification, or document instance:
+
+    base (as an attribute name): denotes an attribute whose value
+         provides a URI to be used as the base for interpreting any
+         relative URIs in the scope of the element on which it
+         appears; its value is inherited.  This name is reserved
+         by virtue of its definition in the XML Base specification.
+
+    lang (as an attribute name): denotes an attribute whose value
+         is a language code for the natural language of the content of
+         any element; its value is inherited.  This name is reserved
+         by virtue of its definition in the XML specification.
+  
+    space (as an attribute name): denotes an attribute whose
+         value is a keyword indicating what whitespace processing
+         discipline is intended for the content of the element; its
+         value is inherited.  This name is reserved by virtue of its
+         definition in the XML specification.
+
+    Father (in any context at all): denotes Jon Bosak, the chair of 
+         the original XML Working Group.  This name is reserved by 
+         the following decision of the W3C XML Plenary and 
+         XML Coordination groups:
+
+             In appreciation for his vision, leadership and dedication

+  <xs:documentation>This schema defines attributes and an attribute group
+        suitable for use by
+        schemas wishing to allow xml:base, xml:lang or xml:space attributes
+        on elements they define.
+
+        To enable this, such a schema must import this schema
+        for the XML namespace, e.g. as follows:
+        &lt;schema . . .>
+         . . .
+         &lt;import namespace="http://www.w3.org/XML/1998/namespace"

+
+        Subsequently, qualified reference to any of the attributes
+        or the group defined below will have the desired effect, e.g.
+
+        &lt;type . . .>
+         . . .
+         &lt;attributeGroup ref="xml:specialAttrs"/>
+ 
+         will define a type which will schema-validate an instance

+   At the date of issue it can also be found at
+   http://www.w3.org/2001/xml.xsd.
+   The schema document at that URI may however change in the future,
+   in order to remain compatible with the latest version of XML Schema

+"""Create thumbnail grids from PowerPoint presentation slides.
+
+Creates a grid layout of slide thumbnails for quick visual analysis.
+Labels each thumbnail with its XML filename (e.g., slide1.xml).
+Hidden slides are shown with a placeholder pattern.
+
+Usage:
+    python thumbnail.py input.pptx [output_prefix] [--cols N]
+
+Examples:
+    python thumbnail.py presentation.pptx
+    # Creates: thumbnails.jpg
+
+    python thumbnail.py template.pptx grid --cols 4
+    # Creates: grid.jpg (or grid-1.jpg, grid-2.jpg for large decks)
