[Biojava-l] Problems for testing demos

[Richard Holland]

This is a basic Java problem, not a BioJava one...

The class lives in the 'seq' folder, and is therefore part of the 'seq'
package. To run it, you must change to the 'demos' folder which contains
the 'seq' folder and type:

	java seq/TestEmbl.java

cheers,
Richard
