Improved jtalk compiler, now named jtalkc in nodejs directory. Not specific to Node anymore.

 These are some experiments of using JTalk together with Node.js:

 trivialserver2  - A variation on trivialserver that tries to do more in JTalk.
 
 You will need "node" in your path to try examples.

-The "compiler" is simply a bash script that uses Nicolas' Exporter/Importer to compile .st files into .js files. The source code should be easy to follow but basically it does the following:
-
-1. Collect all listed (as arguments) .st and .js files. We also check in the JTalk js and st directories if not found.
-
-2. Create a "compiler" by concatenating these files (this means we always use freshest from git):
-        boot.js Kernel.js Parser.js Compiler.js init.js nodejs/nodecompile.js 
-
-3. Run this "compiler" using node and give .st files as command line arguments. This produces corresponding .js files. If not all .js files exist afterwards we abort.
-
-4. Build final program.js by concatenating:
-
-        boot.js
-        Kernel.js
-        ...all .js libraries collected in step 1.
-        ...all .js files produced from the .st files in step 3.
-        init.js (either locally or from JTalk js directory)
-        main.js (if found locally)
-
-5. Run program.js using node if "-r" was specified.

+Usage: $0 [-N|D] [-K|C] [-m class] [-M file] [-i file] [-I] [-r] file1 file2 ... file3 Program
+
+   Will compile Jtalk programs in a variety of ways.
+   Files listed will be handled using these rules:
+
+     *.js files are concatenated as is. If not found we look in $JTALK/js
+
+     *.st files are compiled into .js files. If not found we look in $JTALK/st.
+     Each file is currently considered to be a fileout of a single class
+     category of the same name as the file.
+
+  -N or -D
+     Compile for Node.js or D8 (V8 shell). Defaults to "-KIm Main" so boot.js and Kernel.js
+     are added first and init.js is added last with a call to Main class>>main.
+
+  -K
+     Add libraries to get minimal JTalk Kernel running. Implies -i.
+
+  -C
+     Add libraries to get minimal JTalk Compiler running. Implies -i.
+
+  -I
+     Add library standard initializer $JTALK/js/init.js
+
+  -i file
+     Add library initializer <file>.
+
+  -M file
+     Add javascript file <file> last acting as main.
+
+  -m class
+     Add call to #main in class <class>. 
+
+
+     Example invocations:
+
+     Compile Kernel.st to Kernel.js:
+
+        jtalkc Kernel.st
+
+     Compile Hello.st to Hello.js and create complete program called
+     Hello-all.js for Node.js including boot.js, Kernel.js, init.js and
+     adding a call to class method #main in class Hello:
+
+        jtalkc -N Hello.st
+
+     Compile two different class categories into corresponding .js files,
+     and manually link with specific boot.js, Kernel.js, init.js and main.js
+     and create complete program called Program.js:
+
+        jtalkc boot.js Kernel.js CategoryOne.st CategoryTwo.st init.js main.js Program
