====== Global Requirements ======

If you want to define a global requirement file you can use the --require parameter. Due to this you can include a genesys extension file (*.gex).
In your extension folder you should create folders for your domain (i.e. "pro/genesys"). Let's create an extension named gloablreq.gex

<code>add is code( a, b is int ) := return a+b;</code>
That file you store at ''extention/your/domain/globalreq.gex'' within your local work folder.

Now you create your main procedure and put it into your work folder as ''main.g''.
<code>print add( 1, 2 )$;</code>

If you try to run your main procedure by
<code>gsys -r main.g</code>
you got an error:

<code>~/global_requirement$ gsys --require de.xsd.globalreq main.g 
In File 'main.g'
[ Err]: 9/1: identifier 'add' unknown</code>

To successfully run this, you can add an global known requirement:
<code>gsys -r main.g --require your.domain.globalreq</code>
and you should get the correct result:
<code>3</code>
