Hi,
Found in \value section of man page for tools::write_PACKAGES:
Invisibly returns the number of packages described in the resulting
\file{PACKAGES} and \file{PACKAGES.gz} files. If \code{0}, no
packages were found and no files were written.
Those days (don't know when this has changed exactly), PACKAGES and
PACKAGES.gz are written, even if no packages were found (which is a
good thing BTW).
Thanks,
H.
