recursive execution of make

[sharan basappa]

Hi,

I would like to have a main make file under a particular directory. Every 
time this make is invoked make should be run under the subdirectories that 
exist under this make. To this end I tried
out the following

1)
all : one two

one two :
TAB $(MAKE) --directory-$@

2)
all : one two

one :
TAB $(MAKE) --directory-$@

two :
TAB $(MAKE) --directory-$@

3)

all : one two

one :
TAB $(MAKE) -C one

two :
TAB $(MAKE) -C two

But none of these seem to work for me.
Where am I going wrong.

Second part of my question is if there is a elegant way of
automatically taking all subdirectories that exist under the current 
directory.
As you can see I am manually listing the directories where make has to be 
run ..
