+======
+
+THIS IS NOT A DOCUMENTATION.
+NO WARRANTIES OF ANY KIND, EITHER EXPRESSED OR IMPLIED!
+
+these are just random notes on what i found useful in getting dmx4linux running.
+it might freeze your computer or boil your lights.
+
+
+A. setting up dmx4linux
+=======================
+note: there are debian(etch)-packages for dmx4linux,
+ but these seem to be pretty old (2.5)
+ i haven't really tried these.
+ instead i used dmx4linux-2.6.1
+
+first get dmx4linux from http://llg.cubic.org/dmx4linux/
+and extract it.
+
+the drivers should compile fine with 2.6.18 kernels, but
+alas! i am using 2.6.25 and there are some quirks to make
+these work.
+
+first of all i had problems compiling the ISA/PCI/parport drivers,
+but since i only wanted to use a USB device, i just disabled those.
+second, dmx4linux's build-system tries to override CFLAGS when building
+the kernel-modules, which newer kernel versions (e.g. 2.6.25) do not like
+at all. i had to modify the makefiles in order to use the EXTRA_CFLAGS
+
+all the changes i did can be found in the dmx4linux2.6.1.patch
+just run:
+% patch -p1 < dmx4linux2.6.1.patch
+
+then do
+% ./configure
+(which will produce a /tmp/dmxconfig.mk)
+and run
+% make
+
+finally become root and do
+# make install
+
+after all has gone well, load the appropriate kernel modules
+
+
+btw, it is always a good idea to read the readme that comes with dmx4linux...
+
+
+B. permissions
+==============
+the dmx device-files created by udev will be owned by root.root and not be
+read/writeable by anyone but root.
+in order to use them as an ordinary user, become root and create a group
+"dmx" and add users who need access to the dmx-devices to this group:
+# addgroup dmx
+# adduser zmoelnig dmx
+
+in theory this should be enough to allow you access to your dmx devices
+the next time you load a dmx-driver
+if you have problems, try plugging your device out and in again
+
+if you don't care for a clean setup, you could also just grant everyone read/write permissions.
+# chmod a+rw /dev/dmx*
+be aware that this might be a security risk.
+
+
+
+C. more drivers
+===============
+for using a "JMS USB2DMX" device, i had some driver problems.
+finally i found
+http://www.opendmx.net/index.php/Linux_ArtNet_Node
+which directed me to
+http://www.erwinrol.com/index.php?opensource/dmxusb.php
+and the "dmx_usb" module which seems to work fine.
+i guess, it will also work for the "enttec opendmx" device

you should now have 2 binary files in the src/ folder called [dmxin] and [dmxout]
-go on and use em!
+B. Installation
+===============
+you should install the binaries (+helpfiles) somewhere Pd can find them.
+i would suggest to put them into
+ </path/to/pd>/extra/dmx512/
+and add this path to the startup-flags of Pd.
+C. Usage
+========
+there should be help-files in the ./help directory
+if not, the useage should be very similar to that of [ctlin] and [ctlout]
+(it's just using DMX512 instead of MIDI)
