A problem nowadays with e-mails seems to be that services are HTML-based,
the "text-only" mode reconstructs ".txt" from the HTML source,
and indentations get lost.
Cheers,
Uwe.

Obviously this is best viewed with a fixed-width font. You can run it
by pasting into a file and running 'tex' on it (plain - not latex), or
there's a PDF link on my blog.

can you explain how it works? I am quite familiar with LaTeX however I can't make head or tail of the magic used in your example.
