          description: `The keys of this object are tag names, and the values are configuration
objects indicating what will be checked for these whole-file tags.

Each configuration object has 3 potential boolean keys (which default
to \`false\` when this option is supplied).

1. \`mustExist\` - enforces that all files have a \`@file\`, \`@fileoverview\`, or \`@overview\` tag.
2. \`preventDuplicates\` - enforces that duplicate file overview tags within a given file will be reported
3. \`initialCommentsOnly\` - reports file overview tags which are not, as per
  [the docs](https://jsdoc.app/tags-file.html), "at the beginning of
  the file"–where beginning of the file is interpreted in this rule
  as being when the overview tag is not preceded by anything other than
  a comment.

When no \`tags\` is present, the default is:

\`\`\`json
{
  "file": {
    "initialCommentsOnly": true,
    "mustExist": true,
    "preventDuplicates": true,
  }
}
\`\`\`

You can add additional tag names and/or override \`file\` if you supply this
option, e.g., in place of or in addition to \`file\`, giving other potential
file global tags like \`@license\`, \`@copyright\`, \`@author\`, \`@module\` or
\`@exports\`, optionally restricting them to a single use or preventing them
from being preceded by anything besides comments.

For example:

\`\`\`js
{
  "license": {
    "mustExist": true,
    "preventDuplicates": true,
  }
}
\`\`\`

This would require one and only one \`@license\` in the file, though because
\`initialCommentsOnly\` is absent and defaults to \`false\`, the \`@license\`
can be anywhere.

In the case of \`@license\`, you can use this rule along with the
\`check-values\` rule (with its \`allowedLicenses\` or \`licensePattern\` options),
to enforce a license whitelist be present on every JS file.

Note that if you choose to use \`preventDuplicates\` with \`license\`, you still
have a way to allow multiple licenses for the whole page by using the SPDX
"AND" expression, e.g., \`@license (MIT AND GPL-3.0)\`.

Note that the tag names are the main JSDoc tag name, so you should use \`file\`
in this configuration object regardless of whether you have configured
\`fileoverview\` instead of \`file\` on \`tagNamePreference\` (i.e., \`fileoverview\`
will be checked, but you must use \`file\` on the configuration object).`,
