Here is updated jaotc --help output I will push.
Note, I did not change any jaotc functionality.

The output has more general wording for --search-path and --directory options so we can extend them later.
And " A : separated list " is mentioned only at the beginning of output:

% jaotc --help
Usage: jaotc <options> list

   list       A : separated list of class names, modules, jar files
              or directories which contain class files.

where options include:
   --output <file>            Output file name
   --class-name <class names> List of classes to compile
   --jar <jarfiles>           List of jar files to compile
   --module <modules>         List of modules to compile
   --directory <dirs>         List of directories where to search for files to compile
   --search-path <dirs>       List of directories where to search for specified files
   --compile-commands <file>  Name of file with compile commands
   --compile-for-tiered       Generate profiling code for tiered compilation
   --compile-with-assertions  Compile with java assertions
   --compile-threads <number> Number of compilation threads to be used
   --ignore-errors            Ignores all exceptions thrown during class loading
   --exit-on-error            Exit on compilation errors
   --info                     Print information during compilation
   --verbose                  Print verbose information
   --debug                    Print debug information
   --help                     Print this usage message
   --version                  Version information
   -J<flag>                   Pass <flag> directly to the runtime system


Thanks,
Vladimir
