- * Replacement for strtok() (a.k.a. poor man's flex)
- *
- * The calling convention is similar to that of strtok.
- * s -			string to parse, if NULL continue parsing the last string
- * delim -		set of characters that delimit tokens (usually whitespace)
- * quote -		set of characters that quote stuff, they're not part of the token
- * escape -		character than can quote quotes
- * was_quoted - if not NULL, stores the quoting character if any was encountered
- * token_pos -	if not NULL, receives a count to the start of the token in the
- *				parsed string
- *
- * Note that the string s is _not_ overwritten in this implementation.
