[Edu-sig] Hello Greece (plus greek xhtml)

Greetings to subscribers in Greece!

That *is* good news.  Python is certainly a fine language and
an excellent one for teaching programming, as it gives you
many of the key concepts relatively painlessly.  Your skills
are transferrable to other, more difficult languages.

Administrators who "haven't heard of Python" and so don't
consider allowing it as a teaching language in their schools
are really missing the boat!

By the way, just recently I was playing around with generating
an xhtml web page listing greek characters, encoding in UTF-8,
which the most recent browsers will decode as an option.

The module below will generate either latin.html or greek.html
from the command line.
