[Yann E. MORIN <yann.morin.1998@free.fr>]

Thomas, All,

On 2014-08-15 15:40 +0200, Thomas De Schampheleire spake thusly:
> This patch introduces support for asciidoc configuration files, specific for
> each output format (html, text, pdf, ...). This is useful to make certain
> tweaks in the document generation.
> 
> If a file docs/manual/asciidoc-<format>.conf is present, it is passed to
> asciidoc as configuration file. If no file for the current format is
> present, the options passed to asciidoc are empty.
