<p>Uploads/pastes are deleted after <?php echo $upload_max_age; ?> days<?php if($small_upload_size > 0): ?>
  unless they are smaller than <?php echo format_bytes($small_upload_size); ?>
  <?php endif; ?>. Maximum upload size is <?php echo format_bytes($max_upload_size); ?></p>
<p><h2>Features</h2></p>
<p>For shell uploading/pasting and download information for the client go to <a href="<?php echo site_url("file/client"); ?>"><?php echo site_url("file/client"); ?></a></p>
<p>You can use the <?php echo anchor("file/upload_history", "history"); ?> to find old uploads using the password supplied when creating the upload.</p>
<p>How to link your pastes:</p>
<ul>
	<li><span class="example">/&lt;ID&gt;/</span> automatically highlight the paste</li>
	<li><span class="example">/&lt;ID&gt;</span> set the detected MIME type and let the browser do the rest</li>
	<li><span class="example">/&lt;ID&gt;/plain</span> force the MIME type to be text/plain</li>
	<li><span class="example">/&lt;ID&gt;/&lt;file extension&gt;</span> override auto detection and use the supplied file extension or language name for highlighting</li>
	<li><span class="example">/&lt;ID&gt;/qr</span> display a qr code containing a link to <span class="example">/&lt;ID&gt;/</span></li>
	<li><span class="example">/&lt;ID&gt;/rmd</span> convert markdown to HTML</li>
	<li><span class="example">/&lt;ID&gt;/ascii</span> convert text with ANSI (shell) escape codes to HTML</li>
</ul>
<p>If your upload is not detected as text, only <span class="example">/&lt;ID&gt;/qr</span> will work as above and all others will simply return the file with the detected MIME type.</p>
