+This simple mod uses nodeboxes to supply a complete set of 3D flanged pipes, 
+along with "valve" and "pump" devices.
+
+Unlike the previous version of this mod, these pipes are rounded, and when 
+placed, they'll automatically join together as needed.  Pipes can go vertically 
+or horizontally, and there are enough nodes defined to allow for all possible 
+connections.  Valves and pumps can only be placed horizontally, and will 
+automatically rotate and join with neighboring pipes as objects are added, as 
+well as joining with each other under certain circumstances.
+
+Pipes come in two variants: one type bears one or more dark windows on each 
+pipe, suggesting they're empty, while the other type bears green-tinted 
+windows, as if full (the two colors should also be easy to select if you want 
+to change them in a paint program).  These windows only appear on straight 
+lengths and on certain junctions.
+
+There are no crafting recipes, yet, but you can use /giveme as usual, namely 
+"/giveme pipeworks:pipe 999" or so, and then place them as needed.  See 
+init.lua for more details.
+
+This mod is intended to be used as a basis or at least as sort of a model for 
+something else to build on (perhaps a nicer-looking oil mod?), and does not 
+provide any of the code necessary to cause anything to flow through them.  Like 
+the pipes, the valve and pump don't do anything useful yet, but you can punch 
+them to turn them "on" and "off".  Note that the valve and pump textures and 
+shapes are not yet complete (hence their boxy appearance).
+
+This mod is a work in progress.
+
+Please note that owing to the nature of this mod, I have opted to use 64px 
+textures.  Anything less just looks terrible.
+
+If you don't need the old node names from the previous version of this mod, 
+edit init.lua and comment-out the 'dofile' line at the top.

+Changelog
+---------
+
+2012-08-24: Added square-ish pneumatic tubes, with their own autoplace code 
+(they do not connect to the steel pipes or their related devices).
+
+2012-08-22: Added outlet grate, made it participate in autoplace algorithm.  
+Extended storage tank to show fill level in 10% steps (0% to 100%).  Added 
+"expansion tank" that appears if the user stacks tanks upwards.  (Downwards is 
+not checked).
+
+2012-08-21: Made storage tank participate in autoplace algorithm.  Tuned API a 
+little to allow for more flexible placement.  Re-organized code a bit to allow 
+for some upcoming rules changes.  Made storage tanks' upper/lower fittins and 
+intake grate participate in autoplace algorithm.
+
+2012-08-20: Added temporary nodes for storage tank and intake grating, but 
+without autoplace.
+
+2012-08-19: Pumps and valves now fully participate in the 
+auto-rotate/auto-place algorithm.
+
+2012-08-18: Total rewrite again.  All pipes are now nice and round-looking, and 
+they auto-connect!  Also added temporary nodes for pump and valve (each with an 
+on/off setting - punch to change).  No crafting recipes yet and the pipes still 
+don't do anything useful yet.  Soon.
+
+2012-08-06:  Moved this changelog off the forum post and into a separate file.
+
+2012-08-05 (multiple updates): Rewrote pipeworks to use loops and tables to 
+create the nodes. Requires far less code now. Added -X, +X, -Y, +Y, -Z, +Z 
+capped stubs and a short centered horizontal segment. Changed node definitions 
+so that the aforementioned "short centered" segment is given on dig/drop.  
+Renamed it to just "pipeworks:pipe" (and pipe_loaded). Added empty/loaded 
+indicator images to the capped ends, removed some redundant comments. Made the 
+empty/loaded indication at the capped end more prominent.
+
+2012-07-21: Added screenshot showing pipes as they look now that nodebox 
+texture rotation is fixed.
+
+2012-07-18: Changed the mod name and all internals to 'pipeworks' instead of 
+'pipes'... after a couple of mistakes :-)
+
+2012-07-12: moved project to github.
+
+2012-06-23: Initial release, followed by reworking the textures a bit.
