About libxml2
=============

Libxml2 is the XML C parser and toolkit developed for the Gnome
project (but usable outside of the Gnome platform), it is free
software available under the MIT License. XML itself is a metalanguage
to design markup languages, i.e. text language where semantic and
structure are added to the content using extra "markup" information
enclosed between angle brackets. HTML is the most well-known markup
language. Though the library is written in C a variety of language
bindings make it available in other environments.

Libxml2 is known to be very portable, the library should build and
work without serious troubles on a variety of systems (Linux, Unix,
Windows, CygWin, MacOS X, RISC Os, OS/2, VMS, QNX, MVS, ...)
