Manual Manager is an add-on for Alfresco Share that adds hierarchically structured documents written using markdown syntax. The editor has live preview and syntax help. The result is kind of a classic help file.
The standard document converters that ship with Alfresco uses OpenOffice (or LibreOffice) for conversion of some documents to PDF. When it comes to converting Microsoft Office documents to PDF or PDF/A, with OpenOffice the end result is sometimes not as good as the original.
