Common source for man page and info document?

[Julian Foad]

I'm getting very annoyed by the mis-match between the man page and the info 
document.  I and Debian and others don't want to lose the man page, and GNU/FSF 
don't want to lose the "info" document.  (I could probably grow to like the 
"info" format if the basic GNU "info" viewer program wasn't so primitive and 
clunky.  It even displays "man" pages (when no "info" exists) WORSE than the 
standard "man" viewer does.)

We need one of those systems that can generate both from the same source.  Any 
realistic ideas?  There must be some in fairly widespread use.
