+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description. Line
+# up the first '|' above the ':' following the base package name, and the '|' on
+# the right side marks the last column you can put a character in. You must make
+# exactly 11 lines for the formatting to be correct. It's also customary to
+# leave one space after the ':'.

+libxml2: libxml2 (XML parser library)
+libxml2:
+libxml2: Libxml2 is the XML C parser library and toolkit. XML itself is a
+libxml2: metalanguage to design markup languages  - i.e. a text language where
+libxml2: structures are added to the content using extra "markup" information
+libxml2: enclosed between angle brackets. HTML is the most well-known markup
+libxml2: language. Though the library is written in C, a variety of language
+libxml2: bindings make it available in other environments.
