I just moved my site to Octopress, which comes preconfigured with the rdiscount Markdown parser, but my archives have a lot of posts that were written with the PHP Markdown Extra syntax. The main syntax I need is for footnotes:
This is my sentence.[^1]
[^1]: This is my footnote.
Kramdown does it, but it's slowing down site generation. As far as I understand rediscount is by far the fastest parser, but it doesn't handle this footnote syntax. Are there others that are faster and have this syntax built in? Thanks so much.
