Detailed Description

A class to check the existence of a new version of the application on the network.

This class requires the cooperation of a server. An instance of this class sends a Web request to a server using a cookie describing the current platform (a Base64-encoded JSON structure). The server is responsible for finding a new version for this platform, if available, and returns the response as a JSON structure.

For debug purpose, the environment variable QTLMOVIE_NEWVERSION_URL can be set to an alternate server. If this URL is defined, it overrides any application-defined URL.
