Greetings Guilers,

I am happy to announce the release of Sly 0.1.=C2=A0 I've been sitting = on
this code for a long time now, and it's great to finally release it.

About Sly
---------

Sly is an experimental 2D/3D video game engine written in pure Guile
Scheme.=C2=A0 It builds upon OpenGL and SDL to provide a fun, hackable
environment for writing games.=C2=A0 Think of it like Emacs but for games.<= br> Unlike traditional game engines which focus on imperative
object-oriented programming with mutable data, Sly exposes a functional
interface and promotes the use of persistent, immutable data structures.
The REPL takes center stage in Sly, as it should.=C2=A0 Rather than the
traditional edit, compile, restart cycle of game development, games
written in Sly can be easily changed at runtime thanks to the integrated REPL server.=C2=A0 To develop a game with Sly, you start with a blank scree= n,
connect to the REPL server, and iteratively build the game model and
interactive features.=C2=A0 Using Emacs + Geiser for this is a joy, BTW.
Video game state changes are very asynchronous which manifests in most
game engines as a collection of event-based callback functions, or
"callback hell" for short.=C2=A0 In Sly, this is abstracted and f= ormalized
into a "functional reactive" programming interface.=C2=A0 "S= ignals" are
used to represent time-varying values, and hackers can use analogs of
the usual functional friends (map, fold, filter, etc.) to transform
signal values with respect to time.=C2=A0 The result is a more declarative<= br> program that automatically responds to state changes.

This initial alpha release of Sly features many example programs
(found in the 'examples' directory) to show off basic features.=C2= =A0 This
includes things like a Minesweeper clone, a 2048 clone, and Conway's game of life.

Sly is still a young project with many limitations:

* No 3D model loading
* Half-baked interface to GLSL shaders
* Slow rendering engine
* No sound effects or music
* No lighting
* No sprite batching
* No instanced rendering
* Still using SDL 1.2 instead of the much improved SDL 2.0
* Incomplete documentation

Help wanted!=C2=A0 I've learned a lot about OpenGL so far, but I could = use
more hands to help improve the renderer's feature set and performance.<= br>
Sly is licensed under the GNU GPL version 3 or later, because there's enough permissively licensed game engines as it is.

In lieu of a mailing list or bug tracker, feedback and bug reports can
be sent directly to my personal email address.=C2=A0 Please join #sly on Freenode for friendly discussion about the project.

More information, including (incomplete) documentation, can be found
on Sly's home page: <http://dthompson.us/pages/sof= tware/sly.html>

My search for a more enjoyable way to build video games was what lead me to the Guile community just over 3 years ago now.=C2=A0 It's been quite= the
ride!=C2=A0 I hope that you enjoy Sly and see the potential for its future<= br> development.

Happy hacking!
