Michael Banck did quite some effort to keep this package alife in Debian
as it is documented in bug #1075399 but finally decided[1]:
I came to the conclusion that it is not worth spending time on and agree
that psicode should be rmoved.
Its a shame to see this scientific software go and thank you Michael for
all your efforts into it but it seems its time to remove it from Debian
now. Thus filing this bug report.
Kind regards and thank you for your work as ftpmaster
Andreas.
