Comment #8 on issue 2336 by address@hidden: Patch: Add layout changing  
command \layout-from for getting context defs from music
http://code.google.com/p/lilypond/issues/detail?id=2336

Ok, I am not altogether happy.  The regexp example with its
\midi { \layout-from { \tempo 4 = 80 } }
makes quite obvious that this is rather \context-defs-from or \output-from  
even though it will most often be used as \layout { \layout-from ...

Its purpose is to adjust context-defs while in an output-def.  Does anybody  
have a better suggestion for its name?  It's pushed to staging already, but  
it would still be pretty painless to change its name.  The name should  
contain a hyphen (to prevent accidental use inside of music).  It serves a  
somewhat similar purpose as \settingsFrom (which is used inside of a single  
context-def and actually could also make use of a hyphen: it is  
less "dangerous" since it does not actively change variables in the current  
module but just returns a context-def).
