bridge-hub

Bridge hub_enabled patch:
this patch adds the hub_enabled option for bridge.

By default the hub_enabled flag is set to 1. In this case nothing changes, the
bridge, as usually, acts as a hub and flood_forward the input pkts to all its
ports. When hun_enabled is set to 0, the bridge stops to flood_forward the input
traffic and takes only the pkts sent to it.
Disabling the hub option is useful to join multiple interfaces into a unique virtual
one, thus becomes possible to have easily ad-hoc network topology using multiple
interfaces. 

For example:


	A(eth0) --- (eth1)B(eth0) --- (eth1)C
		       BRIDGE

evolvotron

This is a patch for `evolvotron_match' a program of Evolvotron (
http://www.bottlenose.demon.co.uk/share/evolvotron/index.htm ).

Instead of comparing the source image and the target one with the
sum-of-squares of pixel value, we use a variation of the Normalized
Compression Distance ( http://www.complearn.org/ncd.html ).

It gets a better result, but still not optimal. After a lot of iteration it
converges with a unique color. 

Maybe the convergence problem is not because of the compare_image()
function...

That's all.

getopt-opt-arg

		glibc getopt() optional argument


This is the problem: 

	foo -abcRdefg

If 'R' is an element that specifies an optional argument, then the "defg"
string is taken as its argument, it is pointed by optarg,
but this is not what the user wants, in fact, he expects that the "defg"
characters are parsed as other option elements. In other words the user
expects this:
	
	foo -abc -R -defg

The solution is to assign arguments to 'R' only in these cases:

mailwrapper

Simple patch to let mailwrapper read ~/.mailer.conf first.
This is useful to let users choose their own wrapper.

rwm

		    Rectangle Window Manager
	  http://www.freaknet.org/alpt/src/patches/rwm

rwm is a modified version of http://www.suckless.org/wiki/dwm.

It adds a new tiling layout: the screen is divided equally for all
the windows. Each window tries to occupy the greatest available space.

Instructions: in config.h in layouts[], add 
 	{ "\\o/",               tilebisect },

Note: this layout has been created and (ab)used for sucast:
