Quick Starting JLambda

To play with JLambda really only requires three things: a jar file, an executable script, and setting an environment variable. So lets do this step by step.

The first thing is to download the jar file and jlambda script. The latest version is 630, and can be found here: jlambda-v630.zip. Its only 236K, so comes in a flash!

This unzips to a directory of the same name: jlambda-v630, which contains two files, the iop.jar file, and the jlambda script.

[~/Desktop]$ unzip jlambda-v630.zip 
Archive:  jlambda-v630.zip
   creating: jlambda-v630/
  inflating: jlambda-v630/jlambda    
  inflating: jlambda-v630/iop.jar    
[~/Desktop]$

The jlambda script can be moved to anywhere you like to keep executable scripts, for example:
```
mv jlambda-v630/jlambda  ~/bin/
```
Make sure that the script is still executable, and that your OS knows where it is:
```
[pvs@serrano ~]$ which jlambda
~/bin/jlambda
[pvs@serrano ~]$ 
```
A rehash may be in order here.

All you need to do now, is set the environment variable IOPBINDIR so that it points to where the iop.jar sits.

[pvs@serrano ~]$ setenv IOPBINDIR ~/jlambda-v630
[pvs@serrano ~]$ jlambda

A fun example to start with would be the clicker example: clicker.lsp. Save this file, and try
```
jlambda clicker.lsp
```
