The cwrap package helps you to automate the generation of Lua/C wrappers around existing C functions, such that these functions would be callable from Lua. This package is used by the torch package, but does not depend on anything, and could be used by anyone using Lua. The documentation is organized as follows :

• Example Use Case
• High Level Interface
• Argument Types
• User Types

DISCLAIMER Before going any further, we assume the reader has a good knowledge of how to interface C functions with Lua. A good start would be the Lua reference manual, or the book Programming in Lua.
