<p>Markdown.awk can run in GNU awk (<code>gawk</code>) and in Busybox awk. It is <em>not</em> fully POSIX compliant and does not run in <code>mawk</code> or <code>nawk</code>. In particular it makes heavy use of the <code>gensub()</code> function and its ability to use paranthesized subexpressions in the replacement text. This feature is not available in the POSIX specified <code>sub()</code> and <code>gsub()</code> functions. Hence it cannot be replaced without effort.</p>

<p>Shellwiki is a Wiki and Content Management System with minimal dependencies. It can run on embedded devices, as well as full size web servers. Its goals are:</p>
<ul>
<li><p><strong>easy deployment</strong></p>

<p>Shellwiki is based on <a href="/software/cgilite/">cgilite</a>, which is included in the installation. It is written in posix compliant shell script, and the markdown renderer is written in <del>posix compliant</del> AWK. The entire wiki system can run with nothing more than a busybox. In fact it can be served from the rescue shell in a Debian initrd, or from an OpenWRT router.</p>
<p><strong>Its precise requirements are:</strong></p>
<li><p><em>Optional:</em> Sendmail for sending password reminders, etc.</p>
</li>

<p>In addition to the Markdown syntax, wiki pages can include Macros, which perform additional functions on a page, like generating an image gallery, including parts of other pages, etc. Macros make Shellwiki truly dynamic and flexible.</p>
<p>Macros are the most easy to write type of extension. See <a href="macros/">Macros</a> for a full list of available macros.</p>

<p>While Shellwiki supports plugins for <a href="dev-theming/">theming</a>, it's apearance can mostly be configured by the user. Pages can be configured to use custom CSS files. In addition page headers and footers are themselves wiki pages which can be modified to add menus, custom logos, links, etc. The same goes for error pages.</p>
<p>For an example, see the <a href="/[wiki]/">technical pages</a> for this wiki.</p>

<p>To enable a multilingual setup you must set a default language in your configuration environment:</p>
<pre><code>export LANGUAGE_DEFAULT=en</code></pre>
<p>Header, footer, and error pages will be included from their respective language version, as will all macro includes, etc. Should a page not exist in a given language, the default page will be displayed instead. However, included elements will still be taken from the respective language version, possibly mixing languages between the selected user language and the default.</p>
