GroupWikiTool.php
==============

GroupWikiTool is used to manage the integrity of resource folders for
wiki pages of Yioop Groups. The tool has a command to look up what is
the path for a wiki page of a given group for a locale. To maintain
previous version of wiki page resources, Yioop writes a .archive folder
in the wiki page's resource folder and uses it to maintain
previous versions of this folder. Before changes to the .archive
folder are made, a LOCK file is written. In the event of a crash before
completion of an operation, this LOCK file might be present and
prevent further changes to the resources in a wiki. This tool let's one
clear this lock. It also allows one to remove the existing .archive folder
and rebuild it from scratch. Finally, it allows a user to save a new version
snapshot of the current resource folder.

Usage
=====
php GroupWikiTool.php command folder

php GroupWikiTool.php clear-lock folder
  if folder is the name of a Group Wiki page resource folder, then this
  operation will remove any LOCK file on the .archive folder

php GroupWikiTool.php path group_name page_name locale_tag
  returns the resource and thumb folders for the given group, page,
  and locale.

php GroupWikiTool.php reset folder
  if folder is the name of a Group Wiki page
  resource folder, then this will delete the current .archive folder and replace
  it with a freshly computed one

php GroupWikiTool.php version folder
  if folder is the name of a Group Wiki page resource folder, then this
  will save a save a new version snapshot to the .archive subfolder
