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
