Of course, you can use non-compiled versions but that is not idea of this framework.
To compile all sources (including your custom listeners and classes) into single standalone cluster just launch:
/compiler.php
from your browser or CLI Mode.
This will compile all sources from /src into /_compiled folder.
The name of the compiled file will be:
skynet_{COMPILATION_TIME}.php
Compiled version includes all required classes and is ready to use.
You can specify compiler output directory in:
/src/Skynet/Tools/SkynetCompiler.php
You can also compile sources from any cluster when you launching Skynet in CLI mode:
php skynet.php -compile
