Usage: ./bootstrap PKG_PROTO PKG_USER PKG_HOST PKG_PATH [PKG_DIR]
PKG_PROTO : the protocol type, e.g. ssh, file or git.
PKG_USER : user on the package root host. May be left out if it
is identical to the local user name.
PKG_HOST : remote host to connect to
PKG_PATH : package root path on the remote host
PKG_DIR : the path where caretaker and all further packages will be installed,
by default ${default_path}
Examples: ./bootstrap ssh '' aneurysm /home/derf/var/packages_root
./bootstrap file '' '' /home/derf/var/packages_root
./bootstrap ssh derf derf.homelinux.org /home/derf/var/packages_root
etc.
