Sorry for giving you a non-working example.  I should have tried it...

It's probably best to use the same functions that are used for the
default uninstall actions (in the default.aap recipe):

	uninstall-local:
	   @uninstall_files(_no.DIAGNOSTICSCRIPTDIR, _no.INSTALL_DIAGNOSTICSCRIPT)

For installing a similar construct could be used:

	install-local:
	   @install_files(_no.DIAGNOSTICSCRIPTDIR, _no.INSTALL_DIAGNOSTICSCRIPT, '0644')

Where "0644" is the mode of the installed file.  This time I verified it
actually works! :-)

Now, this isn't obvious.  It would be possible to define actions to hide
the Python function, but it requires passing two arguments.  Something
like:

	:do install {dir = $DIAGNOSTICSCRIPTDIR} $INSTALL_DIAGNOSTICSCRIPT
	:do uninstall {dir = $DIAGNOSTICSCRIPTDIR} {mode = 0644} $INSTALL_DIAGNOSTICSCRIPT

I suppose the Python functions are actually simpler to use.  They should
be documented though.
