INFO: Installing dependency: coyote
INFO: Installing dependency: cmtotal
```

In this example IDLAstro, coyote, and cmtotal are installed to `share/` and Spextool-4.1 is installed to `spex/4.1`:

**Activate Spextool**

To activate a Spextool in your current shell:

```
source spexactivate 4.1
```

The activation script prepends `share/` and `spex/4.1` to `IDL_PATH`, and any previous activations are replaced. If you activate 4.1, then 4.0 in the same shell, then 4.1 will no longer be present in `IDL_PATH`.

**Test it**

*As of v4.0:*

```
$ idl
IDL> mc_testspextoolpath
```

*or earlier:*
