=head1 NAME
Win32::DBIODBC - Win32::ODBC emulation layer for the DBI
=head1 SYNOPSIS
use Win32::DBIODBC; # instead of use Win32::ODBC
=head1 DESCRIPTION
This is a I<very> basic I<very> alpha quality Win32::ODBC emulation
for the DBI. To use it just replace
use Win32::ODBC;
in your scripts with
use Win32::DBIODBC;
or, while experimenting, you can pre-load this module without changing your
scripts by doing
perl -MWin32::DBIODBC your_script_name
=head1 TO DO
Error handling is virtually non-existent.
