 Inception.pl --image_file=anything --debug_camel --host=xx7.x11.xx3.x14 --port=9000
 Inception.pl --image_file=grace_hopper.jpg --host=xx7.x11.xx3.x14 --port=9000
 Inception.pl --image_file=anything --debug_camel --debug_loopback --port 2004 --host technologic

=head3 In the examples above, the following points are demonstrated:

If you don't have an image handy --debug_camel will provide a sample image to send to the server. 
The image file argument still needs to be provided to make the command line parser happy.

If you don't have a server to talk to, but want to see if most everything else is working use 
the --debug_loopback_interface. This will provide a sample response you can test the client with. 
The module can use the same loopback interface for debugging your bespoke clients.

The --debug_verbose option will dump the data structures of the request and response to allow
you to see what is going on.

=head3 The response from a live server to the camel image looks like this:

 Inception.pl --image_file=zzzzz --debug_camel --host=107.170.xx.xxx --port=9000    
 Sending image zzzzz to server at host:107.170.xx.xxx  port:9000

otherwise it will build and install its own local copies.

 $ [sudo] apt-get install autoconf automake libtool

See the Alien::Google::GRPC for potential additional build dependencies.

At this time only Linux builds are supported.

=head2 CPAN Testers Note

This module may fail CPAN Testers' tests. 
The build support tools needed by this module and especially the 
Alien::Google::GRPC module are normally installed on the 
CPAN Testers' machines, but not always.

The system build tools dependencies have been reduced, so hopefully 
a large number of machines will build without manually installing 
system dependencies.

=head2 NOTE

This is a complex package with a lot of moving parts. Please pardon if this first release has some minor bug or missing dependency that went undiscovered in my testing.
