Changing the Behaviour of UYKFD

UYKFD has various properties, which modify its behaviour.

Properties are stored in the database and can be listed using the "show" command. They can be modified with the "set" command.

The initial (default) value for a property can be defined via an environment variable with the prefix UYKFD_. So, for example, the environment variable UYKFD_FOO defines an initial value for the FOO property. See Configuration.

Once a property has been accessed (used) then the value is stored in the database, so changing the associated environment variable will have no effect (instead, use the "set" command).

All properties are stored internally as strings, but are converted to other types when read. This means that if you set an integer property with some value that is not a valid integer you will get an error later when it is used.
