Configuration parameter syntax

Each line in the configuration files consists of a keyword identifying the option being specified, and a value which is a parameter to be used for this option. The keyword and value can be separated by only white space:

keyword            value

or the keyword and value can be separated by an equal sign and white space:

keyword      =     value

Blank lines in the configuration file are ignored. Comments are prefaced by a # and may appear on the end of a line with actual values:

keyword            value          #  This is a comment

or may be at the beginning of a line:

#  This entire line is a comment . . .

The specification of the keywords is case insensitive so that any combination of upper and lower case letters will have the same meaning. Hence, DCDfile and dcdfile are equivalent. The capitalization in the values, however, may be important. Some values indicate file names, in which capitalization is critical. Other values such as on or off are case insensitive.
