#### 6.7.1 Private Module Installation

The `emodule-define` command arranges for a module to appear in Geomview's Modules browser. The command takes two string arguments; the first is the name that will appear in the Modules browser. The second is the shell command for running the module; it may include arguments (see `(emodule-define ...)`). Geomview executes this command in a subshell when you click on the module's entry in the browser. For example

         (emodule-define "Foo" "/u/home/modules/foo -x")

adds a line labeled "Foo" to the Modules browser which causes the command "/u/home/modules/foo -x" to be executed when selected.

You may put `emodule-define` commands in your `~/.geomview` file to arrange for certain modules to be available every time you run Geomview; See Customization. You can also execute `emodule-define` commands from the Commands panel to add a module to an already running copy of Geomview.

There are several other GCL commands for controlling the entries in the Modules browser; for details, See GCL.
