    int main(int argc, char *argv[])
    argc is the number of arguments, including the program name, which is always the first argument.

    argv[0]..argv[argc-1] are the arguments in order as null terminated strings. The effects of wildcards, quotes and environmental variables depends on your compiler and shell. Some usefull functions are atoi() and the boost libraries lexical_cast
