*                                       *
* This tool is capable of interpreting  *
* simple C constructs (excluding        *
* structs, unions, enums) and then      *
* visualize the memory space.           *
*                                       *
* Macros are not supported.             *
* Built-in functions include:           *
*                                       *
*    printf,                            *
*    malloc,                            *
*    calloc,                            *
*    free.                              *
*                                       *
* The version of the C language         *
* is the ISO/IEC 9899:1999              *
* (also known as C99) with some         *
* advanced keywords omitted.            *
*                                       *
* See the examples for sample C         *
* programs, or write your own code!     *
