Relative links to markdown and static files within a page will be evaluated relative to the
location of that page, and then converted to html links during rendering. For example,
`[example](../other/page.md)` in `content/total/overview.md` will be linked to
`content/other/overview.md`, and then rendered to `/other/overview/` in the HTML output.

<td class="purpose-description" colspan="2">Source file based relative linking Hugo Project sub-folder.<br>
When `sourceRelativeLinksEval` is enabled, source level paths may contain an absolute respository path to the
markdown or static file which needs to be removed before trying to match it with the intended link.
For example, if your documentation is in `/docs/content`, then
`[example](/docs/content/other/page.md)` in `/docs/content/total/overview.md` will be linked to
`/docs/content/other/overview.md`, and then rendered to `/other/overview/` in the HTML output.
