The goal of &kturtle; is to make programming as easy and accessible as possible. This makes &kturtle; suitable for teaching kids the basics of math, geometry and... programming. The commands used to program are in the style of the &logo; programming language. The unique feature of the &logo; programming language is that the commands are often translated into the speaking language of the programmer.</para> <para>&kturtle; is named after <quote>the turtle</quote> that plays a central role in the programming environment. The user programs the turtle, using the &logo; commands, to draw a picture on <link linkend="the-canvas">the canvas</link>.</para> <sect1 id="what-is-logo"> <title>What is &logo;?</title> <para>The first version &logo; programming language was created by Seymour Papert of MIT Artificial Intelligence Laboratory in 1967 as an offshoot of the LISP programming language. From then many versions of &logo; have been released. By 1980 &logo; was gaining momentum, with versions for MSX, Commodore, Atari, Apple II and IBM PC systems. These versions were mainly for educational purposes. LCSI released <application>&Mac;&logo;</application> in 1985 as a tool for professional programmers, but it never caught on. MIT is still maintaining a site on &logo; which can be found on <ulink url="http://el.media.mit.edu/logo-foundation/">http://el.media.mit.edu/logo- foundation/</ulink>.</para> <para>Today there are several versions of &logo; around which can easily be found on <ulink url="http://el.media.mit.edu/logo-foundation/">MIT's &logo; site</ulink> and by a simple <ulink url="http://www.google.com/search?q=logo+programming+kids">Google search</ulink>. This version of &logo; (&kturtle;) is only focused on the educational qualities of the programming language and will not try to suit professional programmers' needs.</para> </sect1> <sect1 id="features-of-kturtle"> <title>Features of &kturtle;</title> <para>&kturtle; has some nice features that make starting to program a breeze.
