#generate(force_build = false) ⇒ Object

Generates and writes the HTML files for the blog. If force_rebuild is false, it will only rebuild pages with posts that have changed, otherwise it rebuilds everything. This does not check for changes to templates or other content – if you make any changes to templates, you must force a rebuild.
