    (description
     "D-Bus is a message bus system, a simple way for applications to
talk to one another.  In addition to interprocess communication, D-Bus
helps coordinate process lifecycle; it makes it simple and reliable to
code a \"single instance\" application or daemon, and to launch
applications and daemons on demand when their services are needed.

D-Bus supplies both a system daemon (for events such as \"new hardware
device added\" or \"printer queue changed\") and a
per-user-login-session daemon (for general IPC needs among user
applications).  Also, the message bus is built on top of a general
one-to-one message passing framework, which can be used by any two apps
to communicate directly (without going through the message bus
daemon).  Currently the communicating applications are on one computer,
or through unencrypted TCP/IP suitable for use behind a firewall with
shared NFS home directories.")

    (description
     "ITS Tool allows you to translate your XML documents with PO files, using
rules from the W3C Internationalization Tag Set (ITS) to determine what to
translate and how to separate it into PO file messages.

PO files are the standard translation format for GNU and other Unix-like
systems.  They present translatable information as discrete messages, allowing
each message to be translated independently.  In contrast to whole-page
translation, translating with a message-based format like PO means you can
easily track changes to the source document down to the paragraph.  When new
strings are added or existing strings are modified, you only need to update the
corresponding messages.

ITS Tool is designed to make XML documents translatable through PO files by
applying standard ITS rules, as well as extension rules specific to ITS Tool.
ITS also provides an industry standard way for authors to override translation
information in their documents, such as whether a particular element should be
translated.")
