Update information for AUSTAL2000 2.4.4:

1) Native Language Support

Several times in the past AUSTAL2000 had to be made available in countries 
with a language other than German. To facilitate this, the language-
specific text has been removed from the program code and placed in a 
separate file. Without the use of such a language package all text is in 
English and without special characters. Further information is provided in
Section 2 and Appendix C of the program documentation.

The English version of AUSTAL2000 is packed with the English language
packages, for Windows with latin1 encoding (codepage 1252), for Linux with
UTF8 encoding.

Beside the German version, a thorough English version of the programm 
system is provided on the webpage www.austal2000.de.


2) Rated odour hour frequencies

In addition to the past procedure of merging all odourants into a single
trace substance "odor", animal-type-specific odourants can be defined and
rated according to the regulation GIRL 2008.  Further information is 
provided in Section 3.10 of the program documentation.


3) Statistical uncertainty at monitor points

The statistical uncertainty is now also written out in the log file for
the concentration values at given monitor points, likewise for the time
series of concentration at monitor points.

In the past it could occur that the estimated uncertainty for the 
concentration of dust has been too low. With the new calculation method
the uncertainty is correctly evaluated for a single source but may be too
high for a set of sources.

4) Other

* Application of a minimum value of 10m for the construction height when
estimating the average surface roughness length.

* Optionally specification of an absolute path for parameter rb.

* Extension of the program documentation.
