1. Introduction

The squirrel standard libraries consist in a set of modules implemented in C++. While are not essential for the language, they provide a set of useful services that are commonly used by a wide range of applications(file I/O, regular expressions, etc…), plus they offer a foundation for developing additional libraries.

All libraries are implemented through the squirrel API and the ANSI C runtime library. The modules are organized in the following way:

• I/O : input and output

• blob : binary buffers manipilation

• math : basic mathematical routines

• system : system access function

• string : string formatting and manipulation

• aux : auxiliary functions

The libraries can be registered independently,except for the IO library that depends from the bloblib.
