KDAriane

h1. Eval operators

KDAriane is provided with basic components for executing shell scripts. 

The choice depends on how many 

* parameters (p), 

* input (i) 

* output (o) you want. 

The operators are named @"eval" + p + i + o @ and call the eponymous .sh script.

When an operator is executed, Ariane launches the script (for example @script.sh@) associated to the operator with giving the following arguments:

<pre>

script.sh parameter-1 parameter-2 ... parameter-p input-1 input-2 ... input-i output-1 output-2 ... output-o

</pre>

In Ariane, every operator has a return value, even if it has no output.
