+;;; Commentary:
+
+;;;; I wrote this since I saw one mode for yacc files out there roaming the
+;;;; world.     I was daunted by the fact the it was written in 1990, and Emacs
+;;;; has evolved so much since then (this I assume based on its evolution since
+;;;; i started using it).     So I figured if i wanted one, I should make it
+;;;; myself.     Please excuse idiosyncrasies, as this was my first major mode
+;;;; of this kind.     The indentation code may be a bit weird, I am not sure,
+;;;; it was my first go at doing Emacs indentation, so I look at how other
+;;;; modes did it, but then basically did what I thought was right
+
+;;;; I hope this is useful to other hackers, and happy Bison/Yacc hacking
+;;;; If you have ideas/suggestions/problems with this code, I can be reached at
+;;;; beuscher@eecs.tulane.edu

+
+;;;; Bison Sections:
+;;;; there are five sections to a bison file (if you include the area above the
+;;;; C declarations section.     most everything in this file either does
+;;;; actions based on which section you are deemed to be in, or based on an
+;;;; assumption that the function will only be called from certain sections.
+;;;; the function `bison--section-p' is the section parser
+
+;;;; Indentation:
+;;;; indentations are done based on the section of code you are in.    there is
+;;;; a procedure `bison--within-braced-c-expression-p' that checks for being in
+;;;; C code.    if you are within c-code, indentations should occur based on
+;;;; how you have your C indentation set up.     i am pretty sure this is the
+;;;; case.
+;;;; there are four variables, which control bison indentation within either
+;;;; the bison declarations section or the bison grammar section
+;;;; `bison-rule-separator-column'
+;;;; `bison-rule-separator-column'
+;;;; `bison-decl-type-column'
+;;;; `bison-decl-token-column'
+
+;;;; flaw: indentation works on a per-line basis, unless within braced C sexp,
+;;;; i should fix this someday
+;;;; and to make matters worse, i never took out c-indent-region, so that is
+;;;; still the state of the `indent-region-function' variable
+
+;;;; Electricity:
+;;;; by default, there are electric -colon, -pipe, -open-brace, -close-brace,
+;;;; -semicolon, -percent, -less-than, -greater-than
+;;;; the indentation caused by these work closely with the 4 indentation
+;;;; variables mentioned above.
+;;;; any of these can be turned off individually by setting the appropriate
+;;;; `bison-electric-...' variable.     or all of them can be turned off by
+;;;; setting `bison-all-electricity-off'
+
+;;;; todo:  should make available a way to use C-electricity if in C sexps
