+This script attempts to automatically convert option descriptions from
+DocBook syntax to markdown. Naturally this process is incomplete and
+imperfect, so any changes generated by this script MUST be reviewed.
+
+Possible problems include: incorrectly replaced tags, badly formatted
+markdown, DocBook tags this script doesn't recognize remaining in the
+output and crashing the docs build, incorrect escaping of markdown
+metacharacters, incorrect unescaping of XML entities—and the list goes on.
+
+Always review the generated changes!
+
+Some known limitations:
+  - Does not transform literalDocBook items
+  - Replacements can occur in non-option code, such as string literals
