n3s is a preprocessor and command line editor for the Notation3 [1]
serialization of RDF, written in Python [2], and available as a binary. It
converts abbreviated N3 into "proper" N3, pretty printing along the way -
getting rid of quirky whitespace and so on.

Example use:-

   $ n3s -s '{ ?x rdfs:label ?z } => { ?z :labelOf ?x }'

   @prefix : <#> .
   @prefix log: <http://www.w3.org/2000/10/swap/log#> .
   @prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> .

   this log:forAll :z , :x .
   { :x rdfs:label :z } log:implies { :z :labelOf :x } .

It's for those of you who are sick of typing "@prefix log:..." constantly,
and always liked echo. Note that there are some other funky features, such
as the -i cmdline option (which can use a set of prefixes etc. from a
local/Web file); all documented, at the homepage.

Note also that n3s also understands the @keyword, @use, and @prefix default
constructs suggested by TimBL in [3]. Although I'm not quite sure of the
utility of these yet, I thought it would be a nice proof-of-concept to
implement them.
