# - Single-page document.
# - Requirements to the md-souces:
# - Don't use links without anchors. It means, that you can not just link file. You should specify an anchor at the top of the file and then link to this anchor
# - Anchors should be unique through whole document.
# - Implementation:
# - Script gets list of the file from the `pages` section of `mkdocs.yml`. It gets commented files too, and it right.
# - Files are concatenated by order with incrementing level of headers in all files except the first one
# - Script converts links to other files into inside page links.
# - Skipping links started with 'http'
# - Not http-links with anchor are cutted to the anchor sign (#).
# - For not http-links without anchor script logs an error and cuts them from the resulting single-page document.
