<h2>Source Repositories</h2>
<dl>
<dt><a href="http://git.os.pehjota.net/pkg/">Packages in Git</a></dt>
<dd>Most source packages are maintained in Git repositories. To assist in the maintenance of a package, coordinate with its maintainer(s) and the <a href="http://www.pehjota.net/contact.html">system administrator</a>.</dd>

<h2>Policies</h2>
<p>Packages must adhere to a number of policies for distribution as part of this operating system.</p>
<dl>
<dt><a href="http://policies.os.pehjota.net/packaging.html">Packaging Policy</a> (to be written)</dt>
<dd>Requirements for package naming, splitting, and data.</dd>

<dd>Legal and technical requirements to protect user freedom and to ensure that all included software can be legally distributed and effectively supported.</dd>
</dl>
<h2>Development Environment</h2>
<p>All packages are cross-built using a toolchain consisting of kernel headers, GNU Binutils, GCC, and a standard C/C++ library. The cortexa8-linux-eglibc port, for example, is <a href="http://git.os.pehjota.net/notes/free-embedded-os.git/tree/temporary-bootstrap-builder-setup-cortexa8.txt">currently built</a> using Linux-libre 3.2.7, GMP 5.0.2, MPFR 3.1.0, MPC 0.9, Binutils 2.22, GCC 4.6.2, and EGLIBC 2.15.</p>
<p>This operating system currently supports the following programming languages: C (ISO/IEC 9899 as <a href="http://gcc.gnu.org/onlinedocs/gcc/Standards.html">implemented by GCC</a>), C++ (ISO/IEC 14882 as <a href="http://gcc.gnu.org/onlinedocs/gcc/Standards.html">implemented by GCC</a>), UNIX shell command language (POSIX.1-2008 XCU), and microprocessor assembly languages (with syntax and directives as implemented in GNU as). Support for more languages (e.g. Perl and Python) will come as their respective interpreters and compilers are packaged; this may take time as these programs usually have many build-time and run-time dependencies and some of these programs cannot easily be cross-built.</p>
<h2>Remaining Tasks</h2>
<p>The following is an overview of development work that needs to be done before the operating system can be considered ready for production use.</p>
<h3>Boot Sequencing</h3>
<h3>Multiarch</h3>
<h3>Installation Bootstrap Tool</h3>
<h3>Package Cross Building Tool</h3>
<h3>Multiarch Toolchain Packages</h3>
