[556]	12	! 07/09/10 - Siggi - bugfix in 2201 statement: closing " was missing
	13	! unknown - Siggi - mrun environment variables are read from NAMELIST instead
	14	! of using GETENV. Variables are always assigned a value,
	15	! also if they already got one. These values are re-assigned
	16	! later in mrun.
[72]	17	! 28/02/07 - Siggi - empty lines in configuration file are accepted
	18	! 01/11/05 - Siggi - s2b-Feld erlaubt den Wert locopt
	19	! 29/06/05 - Siggi - Fehlermeldung ins englische uebertragen und ergaenzt
	20	! 29/04/05 - Siggi - extin wird auch fuer Input-Dateien ausgegeben
	21	! 18/11/97 - Siggi - Komma in 2010-FORMAT hinzugefuegt
[1]	22	! 21/07/97 - Siggi - Erste Fassung

[72]	24	! Description:
[1]	25	! -------------
[72]	26	! This program reads the mrun-configuration file .mrun.config and outputs
	27	! its content in form of ksh-commands, which can then be executed by mrun.
	28	! mrun is also able to directly read from the configuration file by using
	29	! the option "-S" (but with much slower speed).
