 SWI-Prolog is a fast and powerful ISO/Edinburgh-style Prolog compiler with a
 rich set of built-in predicates. It offers a fast, robust and small
 environment which enables substantial applications to be developed with it.
 .
 SWI-Prolog additionally offers:
 .
  * A powerful module system
  * Garbage collection
  * Unicode character set handling
  * Unbounted integer and rational number arithmetic
  * Multithreading support
  * A powerful C/C++ interface
  * GNU Readline interface

 This package provides libraries to parse SGML, XML and HTML data into Prolog
 data structures. The high-level interface defined in SGML provides access at
 the file level, while the low-level interface defined in a foreign module
 works with Prolog streams.
