-      Skribilo is a free document production tool that takes a

+      and LaTeX for high-quality hard copies.
 
       The input document can use Skribilo's markup language to provide
-      information about the document's structure, which is similar to
-      HTML or LaTeX and does not require expertise. Alternatively, it
-      can use a simpler, "markup-less" format that borrows from Emacs'
-      outline mode and from other conventions used in emails, Usenet
-      and text.
