OpenGroupware Coils Optional Dependencies

Installing OpenGroupware Coils via easy_install or pip will automatically install a variety of required dependencies.  There are however serveral optional dependencies.  The server will run without the availability of these modules but some features will be automatically disabled.  Installing the following modules will extend the capabilities of your OpenGroupware Coils instance.

• informixdb - Allows an Informix RDBMS to be used as an external data source.  This means you can define an Informix database via OIESQLDataSources and utilize it for SQL related workflow actions such as sqlInsertAction, sqlSelectAction, etc... 
• z3c.rml / zope.interface - Installing these modules will enable the conversions of XML to PDF.  Using XSLT transforms you can turn your data into RML, and then using the rmlToPDF workflow action convert the data into sophisticated PDF documents.
• pysmbc - Enables the OIE workflow engine to retrieve and upload files from or to a CIFS / SMB volume. 
• PIL - Enables the OSSF module for retrieving thumbnails of images stored in OpenGroupware projects or attachments. 
• paramiko - Presence of this module activates the SSH related OIE workflow actions such as sshExecuteCmmand. 
• python-ldap - The availability of the LDAP module enables both support for LDAP authentication (such as when using Active Directory, OpenLDAP, etc... as your user database) and support for querying an LDAP DSA from a workflow process using OIE's ldapSearchAction.

Once your OpenGroupware Coils instance is up and running you should evaluate which additional, optional, dependencies would be useful in your environment.
