  Wumpus - (W)riter (M)onad (P)ost (S)cript. 
  .
  Wumpus is a library for generating 2D vector pictures, its 
  salient feature is portability due to no FFI dependencies. 
  It can generate PostScript (EPS) files and SVG files. The 
  generated PostScript code is plain [1] and quite efficient 
  (no unnecessary stack operations).
  .
  Pictures in Wumpus are made from /paths/ and text /labels/. 
  Paths themselves are made from points. The usual affine 
  transformations (rotations, scaling, translations) can be
  applied to geometric objects. Unlike PostScript there 
  is no notion of a current point, Wumpus builds pictures in a
  coordinate-free style. There is a set of combinators for 
  composing pictures (more-or-less similar to the usual pretty
  printing combinators).
  .
  With revision 0.15.0 I\'ve added three extra helper modules
  that are not really part of the \"core\", but they provide 
  lists of named colours and fonts.
  .
  WARNING...
  .
  wumpus-core is likely to change quite a bit with the next 
  revision as I want to see if I can make Primitives 
  support affine translations. Hopefully this will not change 
  the API significantly though it will mean the generated 
  SVG and PostScript files will be different (possibly 
  clearer). Also the Core.BoundingBox module is not too well
  designed, too many functions that do not offer distinct
  functionality. Some functionality was removed in this revision
  (0.17.0) and more is likely to follow. 
  .
  GENERAL DRAWBACKS...
  .
  For actually drawing pictures, diagrams, etc. Wumpus is very 
  low level. I\'ve worked on a complementary package 
  @wumpus-extra@ with higher-level stuff (polygons, arrows etc.)
  but it is too unstable for Hackage. Preview releases can be
  found at <http://code.google.com/p/copperbox/> though.
  .
  Some of the design decisions made for wumpus-core are not 
  sophisticated (e.g. how attributes like colour are 
  handled, and how the bounding boxes of text labels are 
  calculated), so Wumpus might be limited compared to other 
  systems. However its design permits a simple implementation - 
  which is a priority. Text encoding an exception - I\'m not 
  sure how reasonable the design is. The current implementation 
  appears okay for Latin 1 but I\'m not sure about other 
  character sets, and I may have to revise it significantly.
  .
  With revision 0.14.0, I've added the first draft of a user 
  guide. Source for the guide is included as well as the PDF as 
  there is an extra example picture.  @wumpus-extra@ hasn\'t 
  received any more attention unfortunately, so Wumpus is still 
  really a bit too primitive for general use. However, if you 
  want FFI-free vector graphics and Wumpus seems to otherwise 
  fit the task, please email me and I will try to help.
  .
  \[1\] Because the output is simple, straight-line PostScript 
  code, it is possible to use GraphicsMagick or a similar tool to 
  convert Wumpus'\s EPS files to many other formats (bitmaps).

  Changelog:
  .
  0.16.0 to 0.17.0:
  .
  * Added Core.WumpusTypes to export opaque versions of
    datatypes from Core.PictureInternal. This should make
    the Haddock documentation more cohesive.
  . 
  * Moved the Core.PictureLanguage module into the Extra
    namespace (Extra.PictureLanguage). This module change
    in detail, if not in spirit in the future as I'm not 
    to happy with it. Also this model is somewhat 
    \"higher-level\" than the modules in wumpus-core, so 
    a different home seems fitting. 
  . 
  * Removed CardinalPoint and boundaryPoint from BoundingBox.
  .
  * Argument order of 'textlabel' and 'ztextlabel' changed so
    that Point2 is the last argument.
  .
  * PathSegment constructor names changed - this is an internal
    change as the constructors are not exported.
  .
  * Primitive type changed - moved Ellipse properties into 
    PrimEllipse type - internal change.
  .
  * Removed dependency on \'old-time\'.
  .
  0.15.0 to 0.16.0:
  .
  * Additions to Core.Geometry (direction, pvec, vangle, 
    circularModulo).
  .
  * Fixed error with langle due to not accounting for circle 
    quadrants in Core.Geometry.
  .
  * Point2 now derives Ord - so it can be used as a key for
    Data.Map.
  .
  * Added escape-character handling to text output in PostScript.
    This was causing a nasty bug where a drawing would completely
    fail when special chars shown (GhostView gives little hint of 
    what is wrong when such errors are present).
  . 
  * Changed BoundingBox operation 'corners' to return a 4-tuple
    rather than a list.
  .  
  * Added centeredAt to PictureLanguage
