Setup for NeXtOpt:
1. Set the NMROOT and JAVAHOME environment variables (same as done for a normal NeXtMidas installation).
2. Start X-Midas.
3. Define the NXM option tree:
```
X-Midas> xmopt nxm $NMROOT/nxm/sys
```
4. Add NXM to the path
```
X-Midas> xmp +nxm
```
5. Use XMBOPT to build the UCL option tree.
```
X-Midas> xmbopt ucl
```
6. Now, use XMBOPT to build the NXM option tree.
```
X-Midas> xmbopt nxm
```
