I could use Pandoc to build HTML from my site sources.
I could use it to convert them to different sources.
I’m not saying I would. But I could.
Okay I might.
$ pandoc --to org _posts/programming/2014-12-13-duplicate-files.markdown -o 2014-12-13-duplicate-files.org
$ pandoc --to asciidoc _posts/programming/2014-12-13-duplicate-files.markdown -o 2014-12-13-duplicate-files.adoc
$ pandoc _posts/programming/2014-12-13-duplicate-files.markdown -o 2014-12-13-duplicate-files.html
Honestly at this point I’d say it’s pretty likely.
