and put them into a separate directory. Then register this directory name.
In the example below directory "services" may contain Foo.pm, Bar.pm etc.
Therefore, services Foo and Bar are available. However, these packages must have a function
called methodTable returning the names and descriptions of all possible methods to invoke.
See the documentation and examples for details.

=head1 ABSTRACT
Macromedia Flash Remoting server-side support.
=head1 DESCRIPTION
This file accepts the data and deserializes it using the InputStream and Deserializer classes.
Then the gateway builds the executive class which then loads the targeted class file
and executes the targeted method via flash remoting.
After the target uri executes the the gateway determines the data type of the data
and serializes and returns the data back to the client.
=head2 EXPORT
None by default.
