Modules

A module is a functionality of the program.

A module MAY store data in the store (@sec:thestore). It MAY include user input in the data it stores in the store. A module MUST HAVE a commandline interface, though a module always consists of two parts:

• A Library
• A Binary, which
  • is executable by the user
  • implements a commandline frontend to the libray of the module

By definition, the Binary depends on the Library. By definition, the Library depends on the libstore (@sec:libstore).

A module MUST use the runtime library to implement the commandline interface as defined in @sec:librt.
