+Skribilo -*- Outline -*-
+========
+
+Skribilo is a port of Skribe to GNU Guile.
+
+Here are a few goals.
+
+* Usability
+
+** Integration with Guile's module system
+
+** Better error handling, automatic back-traces, etc.
+
+** Add useful markups
+
+- `document': add `:keywords' and `:language', maybe `:date'
+
+- numbered references
+
+- improved footnotes
+
+** Add an option to continuously watch a file and re-compile it
+
+* Font-ends (readers)
+
+** Implement a new front-end mechanism (see `(skribilo reader)')
+
+** Skribe front-end (read Skribe syntax)
+
+Done.
+
+** Texinfo front-end
+
+Use guile-library's `stexi'.
+
+** Simple markup front-end (à la `txt2tags', Emacs' outline mode, or Wiki)
+
+Almost done (Emacs `outline-mode').
+
+* Back-ends (engines)
+
+** Easier to plug-in new back-ends (no need to modify the source)
+
+** Better HTML (or XHTML?) back-end
+
+** Lout back-end (including automatic `lout' invocation?)
+
+Done, except automatic invocation.
+
+** Info back-end
+
+* Packages
+
+** Pie charts
+
+** Equations
+
+* Toys
+
+** Document browser with guile-gnome
+

+;; Note on writers
+;; ---------------
+;;
+;; `writers' here is an `eq?' hash table where keys are markup names
+;; (symbols) and values are lists of markup writers (most of the time, the
+;; list will only contain one writer). Each of these writer may define a
+;; predicate or class that may further restrict its applicability.
+;;
+;; `free-writers' is a list of writers that may apply to *any* kind of
+;; markup. These are typically define by passing `#t' to `markup-writer'
+;; instead of a symbol:
+;;
+;; (markup-writer #f (find-engine 'xml)
+;; :before ...
+;; ...)
+;;
+;; The XML engine contains an example of such free writers. Again, these
+;; writers may define a predicate or a class restricting their applicability.
+;;
+;; The distinction between these two kinds of writers is mostly performance:
+;; "free writers" are rarely used and markup-specific are the most common
+;; case which we want to be fast. Therefore, for the latter case, we can't
+;; afford traversing a list of markups, evaluating each and every markup
+;; predicate.
+;;
+;; For more details, see `markup-writer-get' and `lookup-markup-writer' in
+;; `(skribilo writer)'.
