The Operating System module is for manipulating operating system primitives such as paths, folders, processes, threads, and mutexes.
The Web module is for interfacing with the World Wide Web.
The SQLite module is for manipulating SQLite databases.
The Zip module is for manipulating Zip files and compressing data.
The Native Interface module is for calling native functions in a shared object (.so) or dynamically linked library (.dll).
