Description:

The libPropList library, hereafter referred to as PL, uses an opaque
data type to represent a tree structure made of strings, data blocks,
arrays and dictionaries (key-value pair lists). This structure can be
manipulated, written out to and read in from a file, and synchronized
with the contents of a file. The purpose of PL is to closely mimick
the behaviour of the property lists used in GNUstep/OPENSTEP (there
formed with the NSString, NSData, NSArray and NSDictionary classes)
and to be compatible with it. PL enables programs that use
configuration or preference files to make these compatible with
GNUstep/OPENSTEP's user defaults handling mechanism, without needing
to use Objective-C or GNUstep/OPENSTEP themselves.
