The Include module implements a method of using #define constants from C header files. It does this by putting an extra level of indirection on the use operator. To enhance performance a cache scheme is used. When a new module is required the cache is checked first, if the package is not found then it will be generated from the C header files. Include can be configured to place any generated packages into the cache automatically, for security reasons this is turned off by default. WWW: http://search.cpan.org/dist/Include
