	R now needs NAMESPACE file ==> Edited NAMESPACE file

	read.gnumeric.sheet: warning in read.csv(pipe(cmd), head = head,
	encoding = "UTF-8", ...): partial argument match of 'head' to
	'header' ==> now use 'header' for read.csv

	(version 0.7-1)

	(Sun Mar 27 22:07:19 2011)

	Using --export-type=Gnumeric_stf:stf_assistant (instead of
	--export-type=Gnumeric_stf:stf_csv) for better control of output
	from ssconvert.

	When reading full sheets, now we avoid using an undocumented
	option of ssconvert (--export-range). We are still using it though
	for partial sheets.

	read.gnumeric.sheet:
	    - bottom.right defaults to NA instead of 'IV65536'
	    - new arg: locale='C', ## value for: ssconvert -O "locale=C"
	    - new arg: field.format='automatic',
	                     ## For: ssconvert -O "format=value".
                             ## Options: raw automatic preserve

	(Mon Mar 21 09:43:25 2011)
	Merged documentation of read.gnumeric.range to read.gnumeric.sheet.
	Removed assignments from \usage{} sections.

	(version 0.6-2)

	(Wed Feb  9 22:51:36 2011)
	Use  single quotes (not double quotes) around sheet name in
	ssconvert --export-range="'Sheet1'!A1:Z100"
	ssconvert 1.10.13 appears to require this.
	Also:  use double quotes (not single) around "filename.gnumeric",
	otherwise file not found. Windows does not understand single quotes?

	(version 0.6-1)

	(Thu Sep  2 08:58:24 2010)
	'grep ,' workaround to exclude diagnostic messages from
	ssconvert's standard output removed

	Value returned by Sys.which() tested with file.exists

	read.gnumeric.sheet adds double quotes around sheet name for
	ssconvert. This should allow reading from sheets with spaces and
	hyphens in their names.

	(version 0.5-3)

	(Tue Sep 1 11:23:35 2009) under unix, use 'LANG=C ssconvert' to
	avoid decimal comma instead of decimal dot in ssonvert output
	under e.g. hungarian locale

	(Thu Sep 17 00:20:17 2009) add gnumeric.xml.read.sheet.names,
	gnumeric.xml.read.sheet.info, gnumeric.xml.read.sheets. Now depends on
	package XML
