cherryEPG follows the the Unix philosophy - Do one thing and do it well. Therefore you will see that it relies on different Linux tools.
From the first day of operation cherryEPG the user interface was command line - CLI. At the moment still all maintenance tasks have to be done via the mentioned CLI. There is a single command line tool to configure, manage and control the complete system. This tool is calling functions from various modules or libraries.
However CLI is fast but a picture is worth a thousand words. Therefore a website can provide better overview of the system behavior. Even for various tasks it can be easier to use a web-browser than writing cryptic commands in the CLI. cherryEPG is also providing a web-interface which offers a fast overview of the system status and basic functionality of configuring the EPG building process.
cherryEPG is completely written in Perl 5.
In this way you can adapt functions that go beyond the possibilities of those contained in the configuration files. Of course, this requires some advanced knowledge of Perl programming.
