> The Linux kernel's IEEE 1394 subsystem provides access to the raw 1394 bus
through the raw1394 module. This includes the standard 1394 transactions
(read, write, lock) on the active side, isochronous stream receiving and
sending and dumps of data written to the FCP_COMMAND and FCP_RESPONSE
registers. raw1394 uses a character device to communicate to user
programs using a special protocol.

> libraw1394 was created with the intent to hide that protocol from
applications so that

handling a complicated command structure.

> To fully achieve the goals (especially 3) libraw1394 is distributed under
the LGPL (Lesser General Public License - see file COPYING.LIB for more
information.) to allow linking with any program, be it open source or
binary only. The requirements are that the libraw1394 part can be
replaced (relinked) with another version of the library and that changes
to libraw1394 itself fall under LGPL again. Refer to the LGPL text for
details.
