#2 Help output for command-line tool needs to be tidied up

[Zencat]

Currently, the output from using the -h or --help option with the command-line tool produces the following output:

usage: timeclockj [command] [OPTIONS]
Tool to clock-in and -out and produce reports. Commands: in | out | report

It should be changed so that the output produces:

usage: timeclockj [command] [OPTIONS]
Tool to clock-in and -out and produce reports.
Commands: in | out | report.
Try timeclockj [command] -h or --help for individual commands.
