+
+Enigma is an interpreted programming language. With it you can create computer
+software. Enigma is not recommended for industrial use. It does work, however.
+
+An Enigma interpreter along with a few tests can be downloaded
+[[enigma-0.1.tar.gz][*here*&large]]. It's relatively stable. I had to write it in Java, as I had to do
+an exam project in Java and I didn't want to create a programming language
+*and* a random Java program at the same time. I would've liked to write it in C
+otherwise (for the experience and for a FFI).
+
+** Documentation
+
++ [[doc/enigma-0.1.pdf][PDF]]
++ [[doc/enigma-0.1-html/][HTML]]
++ [[doc/enigma-0.1.xml][DocBook]]
++ [[doc/enigma-0.1.texinfo][Texinfo (source)]]
+
+Documentation is also included in the program download.
+
+But before you do anything, here's an example of a program:
+
+
+#+BEGIN_SRC
+{/num/
+    1 = res;
+    {/n,r/
+        r n ! multiply;
+        n 1 ! subtract;
+        n 1 ! greater = return;
+    } = facfunc;
+    facfunc num res ! loop;
+    res = return;
+} = factorial;
+
+5 ! factorial | stdout "5! =" temp "\n" ! write;
+7 ! factorial | stdout "7! =" temp "\n" ! write;
+#+END_SRC
+
+This is a factorial program. It will output this:
+
+: 5! = 120 
+: 7! = 5040 
+
+So, while the syntax may be different than eg. C, it's not completely
+incomprehensible.
