-define Package/pugixml/description
-  pugixml is a C++ XML processing library, which consists of a DOM-like interface
-  with rich traversal/modification capabilities, an extremely fast XML parser which
-  constructs the DOM tree from an XML file/buffer, and an XPath 1.0 implementation
-  for complex data-driven tree queries. Full Unicode support is also available,
-  with Unicode interface variants and conversions between different Unicode encodings
-  (which happen automatically during parsing/saving).
