/*
Create a file named 'DEBUG' for enabling debug mode.
For further security, you may put whitelisted IP addresses
in the 'DEBUG' file, one IP per line. Empty file allows anyone(!).
Debugging allows displaying PHP error messages and bypasses the cache: this can allow a malicious
client to retrieve data about your server and hammer a provider throught your rss-bridge instance.
