Usage:
Default usage to get a set (here Alara Reborn)
<info>mtgtutor-console set:info ARB</info>

You can specify a date format via the --date-format option
<info>mtgtutor-console set:info ARB --date-format=d.m.Y</info>

You can change the output format to json with the --json option
<info>mtgtutor-console set:info ARB --json</info>

You can add the full path to the files with --full-path
<info>mtgtutor-console set:info ARB --full-path</info>

You can combine all these options
<info>mtgtutor-console set:info ARB --date-format=d.m.Y --json --full-path</info>
