Pablo Goloboff has generously made available the latest update of his
phylogenetic software PIWE and NONA free of charge as demo versions.
These versions are fully functional though they do require that you hit
an extra key each time that you execute a command.
The software and the documentation are available by anonymous ftp from the
Willi Hennig Society anonymous ftp site: ftp.vims.edu
in the directory: pub/hennig
as file: pars-pag.exe
(a self-extracting DOS zip file)
Or from the Willi Hennig Society's software pages:
but make sure in your browser Preferences' Helper Applications that
files of extension type .exe are set to "SAVE".
