Find lexical use of variables that are dynamically declared in other
files by recording 'defvar' declarations in files that can be read
in by the compiler in a second compilation. This is particularly
useful when converting code to use lexical-binding.
The facility is controlled by setting environment variables:
EMACS_GENERATE_DYNVARS -- set to non-empty to generate a .dynvars file
corresponding to each .elc.
EMACS_DYNVARS_FILE -- set to the name of a .dynvars file to use
as defvar information during compilation,
enabling the new warnings.

suggestion that `setf' has superseded, or is in the process of superseding,
`setq'. Make minor corrections to the English.
* doc/lispref/variables.texi (Local Variables): Make more clear
that local bindings of 'let' are in effect only within the body.
