Not sure if the default reply="reply to list feature" has become
obvious again(?).   Would have to check if there was any printed 
matter on the subject but am under the impression if anything 
stamped "official" came out of the CCP14, it would have be stamped 
and approved by the CCP14 steering committee.  (Am presently in 
Melbourne (and a flakey ISP internet link) so is 
difficult to rummage through the filing cabinets)
Though CCP14 steering committee members may have more 
authoritative and correct statements on the above.

Thus as with all public posts, just my opinion follows.

----

While the original CCP14 promotional material mentions putting
together the "best" software.  With modern internet connectivity, 
I am not sure if this is still applicable as I think it is more of a 
matter of the user matching the most appropriate software to the 
scientific problem at hand; and also having a healthy 
"genetic diversity" of software implying a healthy variation of 
algorithms, methods and approaches are either available or being 
developed.   Using the internet, there is little reason why software 
cannot be routinely "checked out" by users as new problems 
present themselves.  In the Rietveld refinement sphere, that
probably mean around a dozen or more publically available programs
to choose from, all having specialist functionality -  as well 
as numerous vendor supplied products.

In terms of PowderX, following runthrough should speak for itself
to some extent in allowing a quick distance evaluation:
      "Indexing of Y2O3 in 5 easy steps Using PowderX"
       http://www.ccp14.ac.uk/tutorial/powderx/y203.htm

Though this is not exclusive of other software for experimenting
with the data and cross-validating of results.

e.g.,:  Winplotr (peak find/peak profiling) and Windicvol 
       (part of Fullprof98)
     ftp://charybde.saclay.cea.fr/pub/divers/fullprof.98/
     http://www.ccp14.ac.uk/ccp/ccp14/ftp-mirror/fullprof/pub/divers/fullprof.98/

EFELCH/INDEX peak find/profiling/integrated indexing 
from the BGMN Website,
     http://www.bgmn.de/related.html
     http://www.ccp14.ac.uk/ccp/web-mirrors/bgmn/related.html

XFIT or WinFIT, etc for Peak Profiling, CRYS2RUN (which links ITO, 
DICVOL, TREOR) for indexing:

Crys2run:
     http://www.ccp14.ac.uk/tutorial/crys/index.html

CMPR for manual indexing, fundamentals based:

Etc,
