the author considers the package obsolete; its results are (he says) far better achieved by regular use of xetex or luatex.
i have therefore, at his request, moved the package on ctan
from fonts/auto1 to obsolete/fonts/auto1
the change will propagate as usual with ctan mirroring. the catalogue entry
http://www.tex.ac.uk/ctan/help/Catalogue/entries/auto1.html
will have changed by tomorrow morning (cambridge time).
