Command Line Syntax
The general usage models of the CCTK utilities are as follows:
CCTK --option1=[arg1]
or
cctk --option1=[arg1]...--optionX=[argX]
NOTE: Some of the options in CCTK are followed by an asterisk. You can use such options only for reporting
purposes and cannot use the reporting options with set options.
The following table lists the generic command line characters and arguments present in the command line options with
a short description of these characters.
