############################ Browserscan v.1.2 ###########################

Browserscan is a proxy and bot detection script. It evaluates the
browser headers, and searches for inconsistencies. This allows the
script to detect visitors who are not using a standard web browser.

The script recognizes all current PC and Mac browsers for most Operating
Systems, as well as the most popular search engine crawlers and the W3C
validator. Webmasters have the option of automatically banning violators
or using simple logging for a case-by-case evaluation. Notifications
can be enabled to send an email each time the script detects a suspicious
visitor.

The admin panel allows webmasters to sort entries in the database, view
detailed information about each violating visitor, view ARIN whois data,
visit any associated websites, ban/unban, and delete entries.
