    _______________________________________________________

Details:

The exist() function can accept a type which is one of:
builtin, dir, file, var, class.

Octave accepts anything as the second argument and returns 0 without a
warning.  It would probably be nicer to check the type argument during input
validation.

Example:


exist ("sin", "foobar")
=> 0
