that you can use in our images.
I have test all with BH 0.12 image

1.Put my ipk file to/tmp >>Install ipk tools file with Green Panel>>Addons>> Manual Install Ipk packges

Now start TELNET
4.ipk file unpack with the command ipkg-unbuild filename.ipk
example:
ipkg-unbuild enigma2-plugin-extensions-oroscopoitalia-e2-dreamelite_0.1_mipsel.ipk
5.ipk folder packing with ipkg-build foldername
example:
ipkg-build enigma2-plugin-extensions-oroscopoitalia-e2-dreamelite

For pack/unpack you have to use the same folder
Tools folder /hdd/ipkg-tools
