Hi, 

Important update information for PowderX program is in the following:

First, I hope every one who want to use PowderX program will send me 
the signed agreement for using PowderX in duplicates. The last page 
of the User's Manual is the agreement. If you sign it, you will be
informed about the bug fixes and updates of PowderX. 

In addition, please send me e-mail with a reply-to address to single
person, not the whole Rietveld mailing list. In addition, users 
should send me the following information about their Title, 
affiliations, mailing address and Tel. Fax numbers.

Jan. 7, 1999, update information:
    Changes have been made for windows sizes and positions in order to 
fit in the low resolution screen (800x600). (The recommended monitor 
resolution is 1024x768.)
    Now, PowderX can read multi-range *.raw data (begin with raw2) 
collected using Siemens D5000. The program author thanks for kind 
help from Dr.Gyorgy A. Lovas (Eotvos L. University) and Dr.Srebri 
Petrov (Univ. of Toronto).    
    The routines for "ine Print" has been changed, and high quility 
diffraction pattern can be ploted using a laser printer now.    
    The zoomed plot window can be resized and printed out with high 
resolution now.

Dec.28,1998.update information:
   Now, the PowderX can read and process the energy dispersive data from 
Institute of High Energy Physics, Chinese Academy of Sciences. Last item 
the import submenu- Maestro ORTEC (*.chn).

Dec. 27,1998: recent update:

I have fixed a bug in reading Siemens *.raw data. It can read a 
sample data recorded on a new D8 Bruker diffractometer. The data was
supplied by Prof. Armel Le Bail.
 
The problem in reading RIE7 energy-dispersive data then write in 
X-Y two columns XRD data is solved. The "Bragg angle" which might 
be ambiguous is changed to "2theta angle of detector" as suggested
by Dr. Lachlan Cranswick. 
 
------------------------------------------------
Dec. 22,1998: update:
The updated version of PowderX, which now can processing 
energy-dispersive diffraction data of RIET7 and CPI formats. 
In addition, the on-line help may be OK now.

I improve the plot routines to make the resize window
looks better. Printer output is changed too.
