xpand version 1.01 - ) Stuart Hickinbottom 25-Feb-1991
------------------------------------------------------
This application will expand object code which has been compacted using the
Acorn utility 'squeeze', which is part of both the Software Developers Toolbox
and ANSI C. It is actually possible to manually 'unsqueeze' the code, but this
is messy - and after all this utility is only about 900 bytes of ARM code.
Unlike other 'unsqueezers' I have seen, this version SHOULD expand code
compacted with any version of 'squeeze', although I have not tested this
too extensively (if you find one it won't uncompact, then please let me know).
Use 'xpand' just like 'squeeze' - for example:
xpand -h - display program version and date, and also syntax help
xpand prog - expand the squeezed file 'prog', and call the expanded
code 'prog' also - thus OVERWRITING the original
xpand prog bigprog - expand the squeezed file 'prog', and call the expanded
code 'bigprog' - original is unchanged
The expander should notice if the source file is not actually squeezed, and
will also report filing errors (can't find source file, or can't open object
file).
If an error such as 'Abort on data transfer...' or 'No writable memory at
this address' is obtained while expanding then there is not enough memory to
expand the file (either increase Next on the task manager or something
similar).

It may be freely copied and distributed for non-profit making purposes (a
small charge to cover cost of distribution is allowed, however), so long as
the code is not altered and this text file remains present and unaltered. If
you have any queries/suggestions then I would be chuffed to hear from you, so
