In the first example you want it to chop off the /sub/ directory.  Why?  =
What is the indicator as to how many lower directories you want chopped =
off?  In the second example, how can it turn a relative path into an =
absolute path considering that there may be multiple "top" directories =
scattered all over the file system?  How should it know which "top" you =
want it to build an absolute path to?  For example, why not /top/sub or =
/user/top/sub?
