TODO:

- source formating PEAR compliancy
* class style PEAR compliancy
- PEAR compliant error handling
- ident stuff: move index column and table name from *_username to *_user
- think about possible table joins:
	weblog_ident_usernames w/ weblog_remote_idents
	weblog_http_hosts w/ weblog_remote_hosts (what if HTTP_HOST is IP address?)
* session column
- Perl API functions for register hits
- web interface for manipulating with statistics

- why this doesn't work?
