Subject: ConvertComments changes

George:

I found your ConvertComments program right after I tried to javadoc the Acme
classes. I wanted to convert all the files so I modified your program to
recursively process directories. So now if I call "java ConvertComments
Acme", all the .java files in the "Acme" directory will be converted.

I changed main() and added a class called addToFileList(). I thought I'd
send you my changes in case you are interested. The code isn't very good for
two reasons: first, I only spent a few minutes on it, and second, I haven't
done much with java.io before.

Also, I only tested it with passing in a directory name, not a file name. I
only needed the program to work once.


Thanks for writing this program, and thanks for putting the source out
there!
Erik
