Scripting problems...

[Niclas Hedhman]

This script goes through a directory structure and builds up Java
package names out it, so that a directory
abc/def/ghi  will become abc.def.ghi, IF there is a Java file in it
(*.java is given as input).

Now, this is rather slow, and running
find . -name *.java
is a lot faster. But I need to convert the output, so that
a)  the filename is dropped.
b)  the slashes are exchanged for dots

How can this be achieved?
