====== Add a Cluster (recursive) and Class======

Each cluster (to group a set of classes) can be associated with its own folder. In Settings below, a cluster (e.g. cluster "root") is set to recursive. Below we show how to add a new sub-cluster ''model'' to the ''root'' cluster.

===== Add a Cluster =====


For the recursive case, use the terminal (or windows explorer/finder) to create subfolders in cluster "root". To add cluster ''model''"

<code>
>pwd
.../project
>ls
EIFGENs/     project.ecf  root/
> cd root
> mkdir model
> ls
application.e  model/
</code>

===== Add a Class =====


On compiling, the new cluster name ''model'' appears. Right click on ''model'' to add a new class in that cluster.

If we add the file FOO, we obtain

<code>
project/
├── project.ecf
└── root
    ├── application.e
    └── model
        └── foo.e
</code>

===== The ECF File =====

The ECF file looks as follows

<code xml>
<?xml version="1.0" encoding="ISO-8859-1"?>
