awk or sed

[ali hagigat]

I have a variable like this:
var1=Makefile .xcompile /root/build/.config src/arch/i386/Makefile.inc
means some words separated by spaces. I want to print each word on a
separate line. I think I have to use "awk" or "sed" string processing
tools. I wonder if anybody have experience with them or any other
means to do it.
