Hope you never have to do anything complex.  If you call strtok on e string
in the middle of a strtok of another string it trashes its state information
on the first string (a little known feature), which can cause extremely
elusive bugs.  My previous project got stuck with this when we started using
some library code which called it.  For this reason, I avoid strtok like the
plague in all but the simplest applications.
