The Coq Standard Library
Here is a short description of the Coq standard library, which is distributed with the system. It provides a set of modules directly available through the Require Import command.
The standard library is composed of the following subdirectories:
- Init: The core library (automatically loaded when starting Coq)
- Ltac Notations Datatypes Logic Logic_Type Byte Nat Decimal Hexadecimal Number Peano Specif Tactics Tauto Wf (Prelude)
