=head1 NAME

Apache::Mysql - Initiate a persistent database connection to Mysql 

=head1 SYNOPSIS

 use Apache::Mysql;

 $dbh = Apache::Mysql->connect(...);

=head1 DESCRIPTION

This module supplies a persistent database connection to Mysql. You will need to have mysqlperl installed on your system. You should really use Apache::DBI instead of this module (this module was written when DBI::Mysql had problems, which have since been corrected).

This is the first version of the first module I have ever written, so expect errors! Any feedback or suggestions are gratefully received.

All you really need is to replace Mysql with Apache::Mysql. 
When connecting to a database the module looks if a database 
handle from a previous connect request is already stored. If 
not, a new connection is established and the handle is stored 
for later re-use. The destroy method has been intentionally 
left empty.
