Dear professor Matsumoto,

I'm contacting you about a problem we encounted in the Debian Linux
distribution, where we include the well-known PHP interpreter. It includes
Mersenne Twister code written by you.

According to Debian's free software guidelines, the following part of the
licence is not allowed for software in Debian:

" When you use this, send an email to: matumoto at math.keio.ac.jp
    with an appropriate reference to your work"

I would like to kindly ask you to give us or anyone deriving from Debian
permission to remove this condition from the source code, or to rephrase
it as a request but not a requirement (e.g.: "When you use this, please
consider to send an email to...")

If this is OK with you, all that is needed is just a reply to this email
stating that you agree. It would help us very much.

Thank you for your consideration, and we hope to hear from you.

kind regards,
Thijs Kinkhorst
Debian Developer
