• summary usage: summary help/usage (--help)
• summary directory: directory option
• summary end-date: end-date option
• summary output-directory: output-directory option

summary help/usage (--help)

This is the automatically generated usage text for summary.

The text printed is the same whether selected with the help option (--help) or the more-help option (--more-help). more-help will print the usage text by passing it through a pager program. more-help is disabled on platforms without a working fork(2) function. The PAGER environment variable is used to select the program, defaulting to more. Both will exit with a status code of 0.
