  This is the starting file for PhpWiki. All this file does is set
  configuration options, and at the end of the file it includes() the
  file lib/main.php, where the real action begins.

  This file is divided into seven parts: Parts Zero, One, Two, Three,
  Four, Five and Six. Each one has different configuration settings you can
  change; in all cases the default should work on your system,
  however, we recommend you tailor things to your particular setting.

// Part Zero: If PHP needs help in finding where you installed the
//   rest of the PhpWiki code, you can set the include_path here.

// NOTE: phpwiki uses the PEAR library of php code for SQL database
// access. Your PHP is probably already configured to set
// include_path so that PHP can find the pear code. If not (or if you
// change include_path here) make sure you include the path to the
// PEAR code in include_path. (To find the PEAR code on your system,
// search for a file named 'PEAR.php'. Some common locations are:
//
//   Unixish systems:
//     /usr/share/php
//     /usr/local/share/php
//   Mac OS X:
//     /System/Library/PHP
//
// The above examples are already included by PhpWiki. You shouldn't
// have to change this unless you see a WikiFatalError:
//
//     lib/FileFinder.php:82: Fatal[256]: DB.php: file not found
//
// Define the include path for this wiki: pear plus the phpwiki path
// $include_path = '.:/usr/share/pear:/usr/local/httpd/phpwiki';

// The next section controls how many old revisions of each page are
// kept in the database.
//
// There are two basic classes of revisions: major and minor. Which
// class a revision belongs in is determined by whether the author
// checked the "this is a minor revision" checkbox when they saved the
// page.
// 
// There is, additionally, a third class of revisions: author
// revisions. The most recent non-mergable revision from each distinct
// author is and author revision.
//
// The expiry parameters for each of those three classes of revisions
// can be adjusted seperately. For each class there are five
// parameters (usually, only two or three of the five are actually
// set) which control how long those revisions are kept in the
// database.
//
//   max_keep: If set, this specifies an absolute maximum for the
//             number of archived revisions of that class. This is
//             meant to be used as a safety cap when a non-zero
//             min_age is specified. It should be set relatively high,
//             and it's purpose is to prevent malicious or accidental
//             database overflow due to someone causing an
//             unreasonable number of edits in a short period of time.
//
//   min_age:  Revisions younger than this (based upon the supplanted
//             date) will be kept unless max_keep is exceeded. The age
//             should be specified in days. It should be a
//             non-negative, real number,
//
//   min_keep: At least this many revisions will be kept.
//
//   keep:     No more than this many revisions will be kept.
//
//   max_age:  No revision older than this age will be kept.
//
// Supplanted date: Revisions are timestamped at the instant that they
// cease being the current revision. Revision age is computed using
// this timestamp, not the edit time of the page.
//
// Merging: When a minor revision is deleted, if the preceding
// revision is by the same author, the minor revision is merged with
// the preceding revision before it is deleted. Essentially: this
// replaces the content (and supplanted timestamp) of the previous
// revision with the content after the merged minor edit, the rest of
// the page metadata for the preceding version (summary, mtime, ...)
// is not changed.
