"A @dfn{variable} is a name used in a program to stand for a value. In Lisp, "
"each variable is represented by a Lisp symbol (@pxref{Symbols}). The "
"variable name is simply the symbol's name, and the variable's value is "
"stored in the symbol's value cell@footnote{To be precise, under the default "
"@dfn{dynamic scoping} rule, the value cell always holds the variable's "
"current value, but this is not the case under the @dfn{lexical scoping} "
"rule. @xref{Variable Scoping}, for details.}. @xref{Symbol Components}. "
"In Emacs Lisp, the use of a symbol as a variable is independent of its use "
"as a function name."

"This constant is the name of the file where Emacs expects to find the "

"@file{.dir-locals.el}@footnote{ The MS-DOS version of Emacs uses "
"@file{_dir-locals.el} instead, due to limitations of the DOS filesystems. "
"}. A file by that name in a directory causes Emacs to apply its settings to "
"any file in that directory or any of its subdirectories (optionally, you can "
"exclude subdirectories; see below). If some of the subdirectories have "
"their own @file{.dir-locals.el} files, Emacs uses the settings from the "
"deepest file it finds starting from the file's directory and moving up the "
"directory tree. This constant is also used to derive the name of a second "
"dir-locals file @file{.dir-locals-2.el}. If this second dir-locals file is "
"present, then that is loaded in addition to @file{.dir-locals.el}. This is "
"useful when @file{.dir-locals.el} is under version control in a shared "
"repository and cannot be used for personal customizations. The file "
"specifies local variables as a specially formatted list; see @ref{Directory "
"Variables, , Per-directory Local Variables, emacs, The GNU Emacs Manual}, "
