/**
|
|
Since the original (isc.cpp) code wasn't able to provide powerful and
|
|
easy-to-use abilities to work with complex configurations, a decision
|
|
has been made to create a completely new one.
|
|
|
|
This class is used to determine root directory of the installation and
|
|
to get a pathname for the main configuration file. You may ask what's
|
|
treated as root directory. The implementation of this class uses the
|
|
following algorithm (located in getRootDirectory() member function):
|
|
|
|
1. Retrieve full path of the running executable.
|
|
2. If we're either client library or embedded server, return this path.
|
|
3. Otherwise, return parent directory of this path.
|
|
|
|
Pathname of the configuration file is platform-specific and defined by
|
|
getConfigFile() member function.
