//********************************************************************
//*
//* 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_float" or "demo_float" 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.

      // Using the PAS to get a floating license file is just as easy as getting a 
      // node-locked license file.  Getting it set up so client applications can
      // access the licese server and use the new license file, depends on several things.
      //
      // - Is the license server even running ?
      // - If it is, where is it? On this machine or on a different system?
      // - Depending on your Operating System (Windows, Linux, MacOS, etc.), you will
      //   want to set up the license server differently.  For example, on Windows, you
      //   probably want to install sglmd.exe as a Windows Service.  On MacOS, launchd.
      //   
      // - So at this point the process may become more manual.  Refer to the 
      //   LicenseManagerGuide.pdf for instructions on setting up the floating 
      //   license server.
