Log message:
libspectrum is a library designed to make the input and output of some
ZX Spectrum emulator files slightly easier.  It is intended to be usable
on Unix variants, Win32 and MacOSX.

Changes 0.2.0:
        * libspectrum 0.2.0 released.

        * Various data structures (snapshots, tapes, tape blocks) which
          were previously directly accessible are now accessible only via
          wrapper functions. This should improve future binary
          compatability, but at the cost of breaking it for this release
          (Philip Kendall).

        * Change the API for reading/writing snapshots to be more general.
          The old API still exists, but is deprecated (Philip Kendall).

        * Support for reading .szx, .zxs, .sp, .snp and +D snapshots
          (Philip Kendall).

        * Support for writing .szx and .sna snapshots (Philip Kendall).

        * Support for reading Warajevo .tap files (Fredrick Meunier).

        * Support for signing RZX files with digital signatures (Philip
          Kendall).

        * Timing fixes for the TC2048 and TC2068 (Fredrick Meunier).

        * Fix reading of 128K .sna snapshots (Philip Kendall).  

        * New capabilities for the Timex dock, and built-in Sinclair and
          Kempston joysticks (Fredrick Meunier).

        * Use <stdint.h> to give us the <n>-bit types if it's available
          (Philip Kendall).

        * Ignore links to external snapshots from RZX files, rather than
          trying to interpret the path as a snapshot (Philip Kendall).
