Rigaku data format specifications

[Armel Le Bail]

Hi,

Some data conversion programs are able to read Rigaku
powder diffraction standard formats (PowderX, I guess). 
But I have not found any program reading powder data
(in Bruker, Philips, etc) and saving in Rigaku format.

Does such a program exist ?

If not, do the specifications of the Rigaku data formats 
are available somewhere ? What are the formats used 
in the Jade+ software for a search/match with the PDF-2 
database ? Thanks.

Best,
