Ideas and suggestions for next edition

Based on the questions of the students I think that in the next edition we should show:

1. an example with a shp files. Maybe one from GADM (its licence says "The data are freely available for academic use.").
2. how to work with the user-dir?
3. the DCW-collections.
4. how to add a north and scale (basemap -Td and -L).
5. add transparency (-t)

Other suggestions to discuss:
1. Add legends?
2. how to work with makecpt ?
3. how to add text on the map (gmt text)?

Start by reviewing the existing course material and identifying where the proposed examples and topics belong. The issue mentions SHP files, user directories, DCW collections, basemaps, transparency, legends, makecpt, and gmt text; done would require deciding the scope and updating the relevant materials.
