This is one of the possible formats\nsupported by the pretty printer (see <b>pretty_print/2</b>).  The system\nautomatically adds the extension <i>.html</i> and places the result in a\nsubdirectory called 'pretty' relative to the source file.  Syntax coloring\nis used to highlight different language features, and a uniform formatting\nof the source code is used.\n<p>\nAs the clauses are read with the normal Prolog read routine, comments\nwithin clauses are lost, but comments and spacing between clauses is\npreserved.\n<p>\nHyperlinks are used for documented builtin predicates, as well as\npredicates defined in the same file.  For a built-in, the hyperlink\nwill lead to the manual page of the predicate, for other predicates\nthe link points to the first definition of the predicate.  The\nhyperlinks to the builtins are based on the installation directory of\nEclipse, so that the resulting output will normally not work on a\nmachine where eclipse is installed in a different directory.\n<p>\nIf a list of several files is given, an additional index page index.html\nwith links to the individual pretty-printed source files will be generated.\n<p>\nThe pretty printer does not check for undefined predicates or\npredicates that are defined in included files.\n<p>\nThe colours used are similar to those used by the EMACS Eclipse mode.\nColours are used more consistently than in the EMACS editor, as the\nsource text is parsed completely.\n<p>\nYou can modify the colour scheme by modifying the style sheet\nstyle.css which is located in the directory where the .html files get\ngenerated (by default the subdirectory 'pretty').
