How do code change system messages work?

[Marc Worrell]

Hello,

For Zotonic I would like to know when a module is reloaded, so that I can re-check its dependencies.  

For this I need to receive the code change system message for another module than my other (OTP based) module.  

How can I receive those messages?

Best, Marc

Those messages will be sent to OTP processes when a release upgrade is done using the sasl release handling mechanisms.
