Browscap provides an improved version of PHP's get_browser() function.

The get_browser() function can be used to tell what a visitor's browser is
capable of. Unfortunately, the version provided by PHP has a number of
limitations, namely:

* It can be difficult or impossible to configure for shared hosting
  environments.
* The data used to identify browsers and determine their capabilities requires
  consistent maintenance to keep up-to-date.

Browscap automates maintenance by storing browser data in a database and
automatically retrieving the latest data on a configurable schedule.

Requirements
------------

Browscap requires that your server be able to "phone out" (make a http request)
to retrieve and update its user agent database.

Note: Some hosting companies have this capability blocked.

Installation
------------

Browscap can be installed via the standard Drupal installation process.

API
---

Modules can make use of browscap data by calling browscap_get_browser()
anywhere they would otherwise call the PHP get_browser()
(http://us3.php.net/manual/en/function.get-browser.php) function.

Note: browser_name_regex is not returned.
