#********************************************************************
#*
#* This sample demonstrates a real life scenario of using the Product
#* Activation Server for a typical client application.  It first checks
#* whether there is a paid license available, if there is, it will 
#* retrieve it.  If not, then it will attempt to obtain a demo license.
#* available and all criteria are met, then a demo license will be 
#* installed on the client computer next to this running executable.
#*
#* This example checks for a license called 'monitor' '6.0'.
#*
#* If you are testing this on your local host you won't need to change
#* the hostname in the two locations below.  If not, you will need to
#* change 'localhost' to either an IP address or Domain name.
#*
#* MySQL and the Prodcut Activation Server will need to be running,
#* and either of the 'paid_node' or 'demo_node' table records
#* will need to be updated to add the above component name, version, and
#* other information to enable this client app to get a license.  If you
#* use bin/create.sql to create the database and tables, these will be
#* populated for you.
