[[!meta title="Needed Packages"]]

ProteanOS currently has few software packages.  This page lists software that
ProteanOS should eventually provide.


For ProteanOS 1.0
=================

IANA Time Zone Database (`tzdata`)
----------------------------------

https://www.iana.org/time-zones

Time Zone Data represents the history of local time for many representative
locations around the globe. It is updated periodically to reflect changes made
by political bodies to time zone boundaries, UTC offsets, and daylight-saving
rules.


Development
===========

file (`file`)
-------------

http://www.darwinsys.com/file/

file determines file type using magic numbers.

Perl 5 (`perl`)
---------------

http://www.perl.org/

Perl 5 is a language interpreter, especially popular in systems administration
and software build and installation systems.

Unmodified Perl 5 source is impossible to cross build without executing software
on the host system (in GNU Autoconf terms, the system for which the package is
built).  For more information, see this [mailing list thread][perl-cross] and
the [work by Neil Williams for Debian][debian-perl-cross].

GNU M4 (`m4`)
-------------

https://www.gnu.org/software/m4/

GNU M4 is a macro processor, notably used by GNU Autoconf.

Depends on: `perl`

GNU Autoconf (`autoconf`)
-------------------------

https://www.gnu.org/software/autoconf/

GNU Autoconf generates `configure` scripts that are used to configure software
packages for building.

Depends on: `m4`

GNU Automake (`automake`)
-------------------------

https://www.gnu.org/software/automake/

GNU Automake generates `Makefile.in` files that are used to build software
packages.

Depends on: `perl`, `autoconf`

GNU Libtool (`libtool`)
-----------------------

https://www.gnu.org/software/libtool/

GNU libtool is a generic library support script.  Libtool hides the complexity
of using shared libraries behind a consistent, portable interface.

Depends on: `file`, `autoconf`, `automake`


Administration
==============

Dropbear (`dropbear`)
---------------------

http://matt.ucc.asn.au/dropbear/dropbear.html

Dropbear is a small SSH server and client, in many ways compatible with OpenSSH.

A service script (`/etc/init.d/dropbear`) will need to be written, along with
`postinst` and `postrm` maintainer scripts to generate and delete the SSH host
key pair.

libnfnetlink (`libnfnetlink`)
-----------------------------

http://www.netfilter.org/projects/libnfnetlink/index.html

libnfnetlink is the low-level library for netfilter related kernel/userspace
communication.

iptables (`iptables`)
---------------------

http://www.netfilter.org/projects/iptables/index.html

iptables is the userspace command line program used to configure the Linux 2.4.x
and later IPv4 packet filtering ruleset.  It is targeted towards system
administrators.

Depends on: `libnfnetlink`

Lua 5.1 (`lua-5.1`)
-------------------

http://www.lua.org/

Lua is a powerful, fast, lightweight, embeddable scripting language interpreter.

LuCI (`luci`)
-------------

http://luci.subsignal.org/trac

LuCI is a free, clean, extensible and easily maintainable web user interface for
embedded devices.

One or more makefiles may need to be patched to support cross compiling.

There are lots of embedded code copies under `contrib/`; some or all of these
(e.g. uhttpd) should not be built.

Depends on: `iptables`, `lua-5.1`, maybe more
