// Tracker file system calls.

// APIs/code in FSUtils.h and FSUtils.cpp is slated for a major cleanup -- in
// other words, you will find a lot of ugly cruft in here

// ToDo:
// Move most of preflight error checks to the Model level and only keep those
// that have to do with size, reading/writing and name collisions.
// Get rid of all the BList based APIs, use BObjectLists.
// Clean up the error handling, push most of the user interaction out of the
// low level FS calls.
