Hello Dmitry!

I know this is kind of a late reply. I hope you do not mind me
unearthing this. : )

I'm not that proficient at GNU Make yet. I would like to add a way to
cleanup created md and texi files, so that, when I run `make` again, it
creates all files anew.

So I thought I could simply add a `make clean` as follows:

~~~~
.PHONY: clean
clean:
        /bin/rm --verbose *.html *.md *.texi || true;
~~~~

But then I would hardcode the location of `rm` and also it does not work:

~~~~
/bin/rm --verbose *.html *.md *.texi || true;
Symbol’s value as variable is void: /bin/rm
make: *** [Makefile:17: clean] Error 255
~~~~

I think this is, because we have `#!/usr/bin/make -f` at the top, so it
does not know what `/bin/rm/` is. How would you write the makefile to
either add a `make clean` step, or alternatively modify it so that
running `make` will always create the other formats anew?
