To use clone.exe, the following syntax is required:

clone <source> <destination>

For example:

clone a a

will make a copy of drive a to drive a with prompts to the user when
discs are to be swapped.

The program will use all available memory to avoid having to get the 
user to swap the discs too many times.

The source and destination discs must be identical media: the program
will check for this.  Both discs must be formatted.

The program will not perform any action on a fixed disc.

Only drives A and B are recognised.

Some useful information about the source disc is given when it is first
inserted.

Clone will make an identical copy of the disc in every way: the directories,
files, volume label, whether the disc is bootable or not, etc.  All of this
is copied.  The program will stop, however, if any sectors in the source or
destination cannot be read due to physical defects.

A version of the program is available to allow a single disc to be copied
onto several destination discs which is useful in copy software for 
distribution.  This advanced version also has the option of using a fixed
disc as the swap file buffer.  This prevents the source disc having to
be inserted several times.
