Many of the translations have been modified since since they were first submiited,
so the people mentioned here should not be blamed for any errors
that are found.
I am especially grateful to
Dave Bayer (The Hand of John Nash)
who suggested that this translation project should be automated!
Any errors that remain are my own responsibility.
If you see any mistakes please let me know
