Utility to create standard test course. (Also available in GUI interface.)

Not for use on live sites; only normally works if debugging is set to DEVELOPER
level.

Options:
--shortname      Shortname of course to create (required)
--fullname       Fullname of course to create (optional)
--summary        Course summary, in double quotes (optional)
--size           Size of course to create XS, S, M, L, XL, or XXL (required)
--fixeddataset   Use a fixed data set instead of randomly generated data
--filesizelimit  Limits the size of the generated files to the specified bytes
--bypasscheck    Bypasses the developer-mode check (be careful!)
--quiet          Do not show any output

-h, --help     Print out this help

Example from Moodle root directory:
\$ php admin/tool/generator/cli/maketestcourse.php --shortname=SIZE_S --size=S
