Thank you, I'll study this command.

the problem is that the file with the variable to substitute must be read
later, so I must effectively sustitute the value in the file itself.

This is my solution, so far:
I renamed the file with the variable to substitute from themes.scm to 
themes.scin. Then I modified Makefile.am adding:

SUFFIXES = .scm

%.scm: %.scin
	sed -e 's%scwm_themedir%$(scwm_themedir)%' $< > $@
	
and 

DISTCLEANFILES = themes.scm

Now, when I type make, themes.scm is build from themes.scin substituting
scwm_themedir with the value of scwm_themedir. It's not a perfect solution
(problems may arise with file containing "$"), though.
