Release Notes:
______________


    Mn_Fit version 4.04/15 is hereby released.

    The install scripts for all Unix machines have been merged into
one - install.unix.  I need to know the value of the environment
variable SYSTEM on the relevant unix machine. The installation script
for VMS systems is now called install.vms.

    Mn_Fit can also be installed using patchy rather than cmz. The cmz
installation works with version 1.47 of cmz (95a Cernlib). It should
also work with the 1.46 (94b) version, although I have not tested it.
It gives errors with the 94a version. The patchy installation uses
nypatchy if possible. This works well for 95a, but there is a problem
with splitting files in the 94b version, so that you cannot make the
test files.

    The default version of Mn_Fit is now X11 for all platforms.

    Note that this version of Mn_Fit is only compatible with versions
94b, 95a and 96a of the CERN libraries. Most testing has been
done with 95a.

    The C. Rippich version of MINUIT file, minuit.cmz (or .car) has
been renamed to cgr_minuit.cmz. You should delete any minuit.cmz,
minuit.kumac file in you cmz directory.

    Mn_Fit should also be available via my home page on www:
http://wwwcn.cern.ch/~brock

    Some machine dependent information is given below.

HP:
___

There appears to be a bug in the optimizer using the -O option unless
patch http://wsspinfo.cern.ch/patch/PHSS_6311 has been
included. It seems to blow up on lego plot transformations when doing
calculations such as (-2.0 - -2.0)!!
I have therefore changed the default optimization to +O1 for
this version of Mn_Fit.

SGI:
____

Compiling readline with the CC command causes an unresolved external
alloca on the L3 SGI machine. I do not know if this happens elsewhere.
Compiling with gcc is OK.

Sun:
____

The cc command gives an error in hkuip_h.h. This error does not occur
with gcc. If gcc is in /usr/local/lib, this directory is not put in
the default path when compiling from cmz so you must make a link from
your bin directory. e.g. cd ~/bin; ln -s /usr/local/bin/gcc gcc.
Alternatively, when you are prompted for the c compiler command you can
change it to: /usr/local/bin/gcc ...

VMS machines:
_____________

The standard way to define the cmz command on the VMS is:

cmz == "@cern:[pro.exe]cmz"

    This did not work with cmz/batch. You therefore had to redefine cmz to be
something like:

cmz == "$cern:[cmz.pro.exe]cmz.exe"

With the 95a release of the Cernlib the standard definition appears to
work properly, so thee change of the cmz command is no longer necessary.

Apollo:
_______

This version of Mn_Fit has not been tested on an Apollo.
