Class RuntimeConfig
In: lib/taskjuggler/RuntimeConfig.rb
Parent: Object

The RuntimeConfig searches for a YAML config file in a list of directories. When a file is found it is read-in. The read-in config values are grouped in a tree of sections. The values of a section can then be used to overwrite the instance variable of a passed object.
