packs/network_pack.tar.bz2 : network support.
If network support is present the following may be added also :
- packs/ppp_pack.tar.bz2 : ppp support
- packs/w3m_pack.tar.bz2 : w3m text web browser
- packs/MozillaFirebird_pack.tar.bz2 : Mozilla Firebird browser (this package requires also packs/firebird_sup_pack.tar.bz2)
Usually you may add either Firebird or w3m, not the two.
