...

$ cp autobook.info* $HOME/usr/share/info
$ /usr/bin/install-info --info-dir=$HOME/usr/share/info autobook.info

or automated:

# Under Debian you need use 'ginstall-info' instead 'install-info'.
for i in `find . -name "*.info" -o -name "*.info-*"`; do
  cp  $i ~/usr/share/info
  install-info  $i ~/usr/share/info/dir
done
