bibtex-set-dialect is an interactive compiled Lisp function in `bibtex.el'.

(bibtex-set-dialect &optional DIALECT LOCAL)

Select BibTeX DIALECT for editing BibTeX files.
This sets the user variable `bibtex-dialect' as well as the dialect-dependent
internal variables. Allowed dialects are listed in `bibtex-dialect-list'.
If DIALECT is nil use current value of `bibtex-dialect'.
If LOCAL is non-nil make buffer-local bindings for these variables rather than
setting the global values. The dialect-dependent internal variables
are also bound buffer-locally if `bibtex-dialect' is already buffer-local
in the current buffer (for example, as a file-local variable).
LOCAL is t for interactive calls.
