- improvement: long localized messages are in HTML files instead of $lang

  array. This is the case of admin/help and about pages.

- deletion: of unused functions (ts_to_mysqldt, is_image, TN_exists,
  check_date_format, date_convert, get_category_directories,
  get_used_metadata_list, array_remove, pwg_write_debug,
  get_group_restrictions, get_all_group_restrictions, is_group_allowed,
  style_select, deprecated_getAttribute).

- new: many new contextual help pages to replace descriptions previously
  included in pages.

- modification: reorganisation of language files. Deletion of unused
  language keys, alphabetical sort. No faq.lang.php anymore (replaced by
  help.html). Only done for en_UK.iso-8859-1.

+<h2>Edit a category</h2>
+
+<p>Modify informations and options of a single category.</p>
+
+<h3>Action links</h3>
+
+<p>This page offers you link to modification page of parent categories and
+action links :</p>
+
+<ul>
+  <li>jump to category</li>
+  <li>manage category elements (if category contains elements)</li>
+  <li>manage sub-categories</li>
+  <li>manage permissions (if category is private)</li>
+  <li>delete category (if category is virtual).</li>
+</ul>
+
+<h3>Move</h3>
+
+<p>If the category is virtual, you can move it. Moving a category means
+changing its parent category.</p>
+
+<h3>Options</h3>
+
+<ul>
+
+  <li><strong>Access type</strong>: Permission management. If you make a
+  category private, all its child categories becomes private. If you make a
+  category public, all its parent categories becomes public.</li>
+
+  <li><strong>Lock</strong>: The category and its sub-categories will
+  temporary been disabled for maintenance.</li>
+
+  <li><strong>Comments</strong>: Authorize users to comment elements of this
+  category.</li>
+
+  <li><strong>Authorize upload</strong>: Authorize users to upload
+  files. This option is available only if category is physical (not
+  virtual).</li>
+
+</ul>
+
+<p>You can also manage these options with multi-categories options
+management screen (screens <span class="pwgScreen">Upload</span>, <span
+class="pwgScreen">Comments</span>, <span class="pwgScreen">Lock</span>,
+<span class="pwgScreen">Public/Private</span>, <span
+class="pwgScreen">Representative</span> in <span
+class="pwgScreen">Administration, Categories</span>).</p>
+
+<h3>Representation</h3>
+
+<p>The representant of the category is the thumbnail displayed to represent
+the category on main page (<span class="pwgScreen">category.php</span>) when
+a category contains only sub-categories (just as the root category).</p>
+
+<p>There are 4 ways to set the representative picture of a category :</p>
+
+<ul>
+
+  <li><span class="pwgScreen">picture.php</span>: in the action buttons bar,
+  one of them let you set the displayed picture as representative for the
+  displayed category. This button is available only for administrators.</li>
+
+  <li><span class="pwgScreen">Modify informations about a picture</span> in
+  administration. This screen can be reach from <span
+  class="pwgScreen">picture.php</span> or <span class="pwgScreen">Batch
+  management</span> in <em>unit mode</em>. See the help of this screen for
+  details.</li>
+
+  <li><span class="pwgScreen">Administration, Categories,
+  Representative</span>. See the help of this screen for details.</li>
+
+  <li><span class="pwgScreen">Edit a category</span> (this screen).</li>
+
+</ul>
+
+<p>The representation depends on configuration parameter
+<code>allow_random_representative</code> (see <span
+class="filename">include/config_default.inc.php</span>).</p>
+
+<p>In default mode (<code>allow_random_representative</code> set to false)
+each category containing at least one element is represented by a fixed
+element. Once set (at category creation), the representative changes only
+when an administrator ask for it. If the representant is not appropriate,
+you can ask to <strong>Find a new representant by random</strong>.</p>
+
+<p>If configuration parameter <code>allow_random_representative</code> is
+set to true, a category containing elements can have no fixed
+representant. Just use <strong>Delete representant</strong> button.</p>
+
+<p>If the category contains no element (but only sub-categories) it can be
+represented by any element thanks to screen <span class="pwgScreen">Modify
+informations about a picture</span>. The only option on the current screen
+is to <strong>Delete representant</strong> button, after using this button,
+no representant option to set anymore.</p>

 <h2>Synchronize</h2>
+
+<p>There are 2 synchronizations possible : directories/files and file
+metadata. directories/files is about synchronizing your directories tree

+
+<p>The first synchronization must be the directories/files one.</p>
