+define Package/debootstrap/description
+ debootstrap is used to create a Debian base system from scratch, without
+ requiring the availability of dpkg or apt. It does this by downloading .deb
+ files from a mirror site, and carefully unpacking them into a directory which
+ can eventually be chrooted into.
