History
-----------------
29 June 1999: v2.1
	
	* IMPORTANT! Database structure has been modified. Please apply
	create/alter20-21.txt SQL script to fix database structure.

	* Added support for templates to easily customize search results
	appearance. See doc/README.templates for details.

	* Added support for different word forms. UdmSearch use Ispell
	affixes and dictionaries. For example, if you are searching for
	the word 'test', documents contained words tested, tester, testers,
	testing, testings, tests will be found as well. Multiple languages
	are supported. This was tested for English and Russian, but it
	should be extremely easy for other languages too. Ispell is
	supported in both search.cgi and morph.php3 frontends.
	search.php3 works without ispell support, but with boolean logic
	query language.

	* Added support for external parser programs (e.g. programs which can
	convert different [propertiary] formats to plain text or html).
	Tested with .sgml, MS WORD .doc, man files. Adding your own
	parsers is extremely easy.

	* indexer now uses syslog for logging its messages by default.
	Added different verbose levels.

	* MD5 hash of every document is stored in database. This is used by
	search to show document clones, well, documents with the same contents
	but different locations. It is also used by indexer itself to decide
	whether to parse document again or not, which further improves indexing
	speed. If you are upgrading from previous verion, please use
	'indexer -a -m' to reindex proper all documents. Option -m prevent
	indexer from sending 'If-Modified-Since' HTTP header.

	* Various improvements and bugfixes.

	* Added some nice command line arguments to indexer

	- One could easy reindex URLs even if not expired yet.
