-# spellcheck
-
-This filter checks the spelling of words in the body of the
-document (omitting metadata).  The external program `aspell` is
-used for the checking, and must be present in the path.
-
-Why use this instead of just running `aspell` on the
-document's source?  Because this filter is sensitive to
-the semantics of the document in ways that `aspell` is
-not:
-
-- Material in code spans, raw HTML, URLs in links,
-  and math is not spell-checked, eliminating a big
-  class of false positives.
-
-- The filter is sensitive to the `lang` specified in
-  the document's metadata; this will be treated as the
-  default language for the document.
-
-- It is also sensitive to `lang` attributes on native
-  divs and spans. Thus, for example, in an English
-  document, `[chevaux]{lang=fr}` will not be registered
-  as a spelling error.
-
-To run it,
-
-    pandoc --lua-filter spellcheck.lua sample.md
-
-A list of misspelled words (or at any rate, words not
-in the appropriate dictionary) will be printed to stdout.
-If the word is in a div or span with a non-default `lang`
-attribute, the relevant language will be indicated in
-brackets after the word, separated by a tab.
-
-To add words to the list for a language, you can add files
-with names `.aspell.LANG.pws` in your home directory.  Example:
-
-```
-% cat ~/.aspell.en.pws
-personal_ws-1.1 en 0
-goopy
-```
