Good PDF introduction to the GDL language.
Hunting around the web there are people producing extra libraries which can be downloaded :
- NASA IDL Astronomy Libraries
- SDSSIDL – a set of general IDL utilities for plotting, data analysis, and database access
- Daithi Stone IDL Libraries – Geographical, Arrays, Filesystem, Calendar, Graphics, I/O, Maths
- IIT User Community Libraries

Any .pro files downloaded from the internet can be copied to the GDL directory at:
sudo cp *.pro /usr/share/doc/gnudatalanguage/examples/pro/
Then used within your own .pro files.
Potentially Interesting Stuff
In the spirit of Gnu it would be good to have someone create an XText implementation for the Eclipse IDE. A cross-platform libre IDE for GDL would be nice, so that editing, syntax highlighting, compilation, running etc could all be done within one (Eclipse) environment.
