"""
Script to import multiple directories with textile files into Confluence Wikis. Can be used with OnDemand instances.

To use as redmine migration tool, you need to export wiki pages in textile format. One way is described in: http://stbuehler.de/blog/article/2011/06/04/exporting_redmine_wiki_pages.html


~/redmine $ RAILS_ENV=production ./script/console -s

def export_text(p)
  c = p.content_for_version(nil)
  "#{c.text}"
end

def export_wiki(dir, wiki)
  dir = dir + "/" + wiki.project.identifier
  Dir.mkdir(dir)
  wiki.pages.each { |p|File.open(dir + "/" + p.title + ".textile", "w") { |f| f.write(export_text(p)) } }
  true
end

Project.all

export_wiki("/tmp", Project.find(2).wiki)

Thanks for the script.
I've extended it a bit to allow attachments conversion.
