24.4 Options in the mc File

When you create a configuration file with the mc configuration technique (see Chapter 4), you can tune each option by including an appropriate statement in your .mc configuration file:^[5]

^[5] Some mc macros use the define m4 directive, while others don't require that directive. Those that don't are suffixed with parentheses in the table.

define(`option',`value')         enclose in opposing single quotes 
define(`confAUTO_REBUILD',`True')    for example
DAEMON_OPTIONS(`Port=1097')      for example

The option is selected from one of the mc option names shown in the leftmost column of Table 24-3. The value is an appropriate value for that option, as described in the reference section at the end of this chapter. Note that the option and the value should each be enclosed in opposing single quotes to prevent m4 from wrongly recognizing either as a keyword or macro. The leftmost single quote is the reverse apostrophe, and the rightmost is the normal apostrophe.
