ASA is now also listed at http://asa-caltech.sourceforge.net
(http://asa-caltech.sf.net).

========================================================================
21 Nov 06

asa.c:
If Delta_X is set to 0, then no tangents are calculated.  No tangents
are calculated if User_Delta_Parameter[] is 0 for any parameter.

========================================================================
20 Oct 06

ASA-NOTES:
Added 2 URLS to section @@FORTRAN Issues.

========================================================================

asa.c:
When ASA_SAVE is TRUE, corrected size for Asa_Out_File to 80 in fread
and fwrite.

========================================================================
27 Jul 06

asa.c, asa.h:
Moved char exit_msg[160] from asa.h to asa.c to avoid compilation problems
on some systems with some applications that include asa.h in multiple files.

========================================================================
20 Jul 06

Makefile:
When using Cygwin to create a DLL, corrected target asadll: from
-Wl,--export-all-symbol to -Wl,--export-all .

Fixed HTML warning re hr may not occur inside p.

========================================================================
13 Jul 06

When using a DOS version of ASA, e.g., ASA.zip, on a Unix machine, some
systems do not process continuation "\" lines properly.  These lines
are now joined to long lines in the code.

========================================================================
3 May 06

asa_usr.c:
Deleted extra fclose() in ASA_TEMPLATE_SAVE.

========================================================================
26 Feb 06

ASA-README.ms, asa.c:
The final values in asa.c of *best_number_generated_saved and
*best_number_accepted_saved at the best cost function will be those of
the first instance of the final best value.

========================================================================
23 Feb 06

ASA-README.ms, asa.c:
When MULTI_MIN is set to TRUE and Multi_Specify is set to 0, and multiple
best cost functions are found, the parameters of the final cost function
reported will be the parameters of the last best cost function.

When ASA_QUEUE and ASA_RESOLTUION are TRUE, comparisons with a new
generated state are made relative to EPS_DOUBLE, since Queue_Resolution
= Coarse_Resolution.  When ASA_QUEUE is TRUE, dropped a decrement of
number_generated.

When MULTI_MIN is TRUE, asa_exit() calculates cost functions, and their
