 * The following description is from Linux Programmer's Manual (strtok(3)):
 *
 * #include <string.h>
 * char *strtok(char *str, const char *delim);
 *
 * The  strtok() function breaks a string into a sequence of zero or more
 * nonempty tokens.  On the first call to strtok() the string to be parsed
 * should be specified in str. In each subsequent call that should parse
 * the same string, str must be NULL.
