D-BUS is a simple IPC library based on messages.

See http://www.freedesktop.org/software/dbus/ for lots of documentation,
mailing lists, etc.

Note
===

A core concept of the D-BUS implementation is that "libdbus" is
intended to be a low-level API, similar to Xlib. Most programmers are
intended to use the bindings to GLib, Qt, Python, Mono, Java, or
whatever. These bindings have varying levels of completeness.

Configuration flags
===

These are the dbus-specific configuration flags that can be given to
the ./configure program.

--enable-tests enable unit test code
--enable-ansi enable -ansi -pedantic gcc flags
--enable-verbose-mode support verbose debug mode
--enable-asserts include assertion checks
--enable-checks include sanity checks on public API
--enable-xml-docs build XML documentation (requires xmlto)
--enable-gcov compile with coverage profiling instrumentation (gcc only)
--with-xml=libxml/expat XML library to use
--with-gnu-ld assume the C compiler uses GNU ld [default=no]
--with-tags[=TAGS] include additional configurations [automatic]
