 configuration file for `/usr/bin/opkg-cl`.  It also provides a new
 `/usr/bin/opkg-feed` script (similar to Ubuntu's add-apt-repository) that
 manages `src` options in opkg configuration files, e.g. to add a new packages
-feed.  Example usage, for adding the feed for the `dev/platconf` suite, `src`

+    # opkg-feed -a dev/platconf i686-linux-glibc platconf base
     # opkg update
 
 `ppt-make` (which generates a new `config-*` package) from `platconf-pkg-tools`

 A new `ppt-configure` tool is added to `platconf-pkg-tools`.  This tool finds
 and installs all of the available `*-kconfig` packages, builds a single unified
