Two new utilities on the info server: 'iconbarclock' and 'xpand'.

Submitted by Stuart Hickinbottom.

Descriptions:

Icon Bar Clock v1.11
--------------------

This module will display a clock on the desktop icon bar. The clock is
similar in appearance to the clock displayed by !Alarm on the RiscOS
Applications discs.

An additional feature is that the date is displayed on the clockface when
the face is clicked on.

Since the clock is a module it will start up every time the desktop is
started, and also it runs as a module task so that it will only take 3500
bytes of application space (as opposed to a minimum of 16k if it was run as
a normal task).

The clock can be killed by selecting the Quit option from its menu - but it
will reappear when the desktop is next started. To kill it completely use:

*RMKill IconBarClock

Which will permanently remove it from the module area.


xpand version 1.01
------------------

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).

To retrieve a file a file from the archive, send a message to 
info-server@newcastle.ac.uk with the following content:

line-limit 1000
request: sources
topic: archimedes filename
request: end

where filename is replaced by the name of the file that you want.
A filename of 'index' will send you the latest index file.
