  20. =head1 NAME
  21. ikiwiki Plug-in: h1title
  22. =head1 SYNOPSIS
  23. If there is a level 1 Markdown atx-style (hash mark) header on the first line,
  24. this plugin uses it to set the page title and removes it from the page body so
  25. that it won't be rendered twice. Level 1 headers in the remainder of the page
  26. will be ignored.
  27. For example, the following page will have title "My Title" and the rendered
  28. page body will begin with the level two header "Introduction."
  29. # My Title
  30. ## Introduction
  31. Introductory text with a list:
  32. * Item 1
  33. * Item 2
  34. ## Second header
  35. Second section
  36. This plugin can be used with page templates that use <h1> tags for the page
  37. title to produce a consistent header hierarchy in rendered pages while keeping
  38. the Markdown source clean and free of meta directives.
