* 1.0
    - initial release

* 1.1
    - Changed binary name from 'nc' to 'noiseclock' to remove name clash
    with the netcat project. Oops. Also changed man page, etc.
    - Added -c option to produce a grand total (like in du)
    - Replaced calls to ftw with an internal procedure. This should make
    noiseclock more portable across unices that don't have ftw at all, or
    have something like fts instead. Also, it makes program execution 
    roughly 33% faster overall. See dirwalk.c for knowledge. 
    - Added some documentation inside of Makefile on what to change to 
    enable compilation on MacOS X.
    - Found and fixed a memory leak which only happened when using format
    strings.
    - Did minor editing on help text and man page.
