Re: New documentation targets (pdf & txt)

| Okay, I did.  I also got motivated and made the whole kit and kiboodle work,

| I did notice something strange while working on this.  I didn't test it, but

I like your patch, thanks!  Do you have write access?

But the documentation and NEWS bits are lacking.  Also, I confess I
don't understand why, if on the one hand, you define
am_info_CLEANstuff, then, on the other hand, mostlyclean-aminfo is not
simplified.  AFAICS, it still contains hard coded things, right?
