By default, title, author, date and email lines appear in dark blue
with the initial keywords greyed out. The title is in a larger font
than the others. This is implemented by the following new faces:
org-document-title
org-document-info
org-document-info-keyword
In addition, the variable org-hidden-keywords can be used to make the
corresponding keywords disappear.
This new code will search #+INDEX lines in the buffer. For LaTeX, it
will simple convert these into LaTeX \index{} commands. For other
backends, it will copy thee entries to a new file, with extension
orgx. These files can then later be post-processed to create the index.
