[Objcryst-foxx] Test version for Fox 1.1.2

[Vincent Favre-N. <vi...@us...>]

	Hi all,

    First, I would like to thank those among you who have downloaded 
the source and compiled Fox. It has proven slightly more difficult than 
expected (especially with the woes of the wxWindows setup.h files for 
2.2.9), but now the instructions should be OK. I hope that by updating 
more regularly from the CVS tree between realses, there will be more 
feedback and therefore less bugs, especially under windows. (btw, last 
small changes in CVS were made yesterday)

    I have put a new version of Fox (1.1.2, precompiled for windows), 
which is available from:
ftp.unige.ch/soft/pub/crystal/Fox/test/

   This new version will fix-I hope- most annoying bugs (zmatrix faulty 
input, changing spacegroup/unitCell +recomputing crash), and will also 
introduce a few useful features such as introducing a limit in the 
extent of calculations in sin(theta)/lambda, and an *experimental* 
option for twinned single crystal data (contact me for this, as I have 
made absolutely no test on it !).
   I hope to bring more major changes in the next version, ideally 
texture and a new modelization for molecules.

   On an aside note, the license has been changed to the GNU GPL, in 
order to bring more protection to the source code while still keeping 
it free (see http://www.gnu.org/philosophy/philosophy.html).
   Note that if some people want to use ObjCryst++ without being forced 
to reveal their own source code, it will still be possible by asking me 
directly, and it will be granted depending on the mode of distribution 
of the program (freely available being the idea).

    Cheers,

Changelog:
#### 1.1.2 - 2002/02/18
License changed to the GNU General Public License.
NEW FEATURES
   * Added a maximum value of sin(theta)/lambda for diffraction
     data objects. All data above is ignored.
   * Added an *experimental* option in single crystal data for
     twinned data, to work on the sum of metrically-equivalent
     reflections. Entirely untested (contact me to use it !)
	* Some parameter are automatically fixed for global optimizations
	  (unit cell, background & profile parameters).
   * Fox will write a few messages for some key events
     (importing data, creating spacegroup,...)

BUG FIXES
   * Spacegroup and Unit Cell values can now be changed even if
     scattering data has already been computed, without crash.
   * Importing a Z-Matrix would give the 3rd and 4th atoms the same
	  number, and if atoms were of the same type, both atoms would
	  have the same name in the .xml saved file, and would crash
     on reloading. Molecules thus created need to be re-imported.
