* Emulator tools - converting between real floppy discs and disc images, as CPCTRANS / PCWTRANS do under DOS.
* Filesystem utilities - CPMTOOLS is configurable to use LIBDSK, thus allowing the use of CPMTOOLS on emulator .DSK images. To do this, install LIBDSK and then build CPMTOOLS, using "./configure --with-libdsk". For CPMTOOLS 1.9 or 2.0, you will also need to apply this patch.
* Emulators - it is possible to use LIBDSK as part of an emulator's floppy controller emulation, thus giving the emulator transparent access to .DSK files or real discs.
