 ## Choose a width for Emacs.

-## We'd like it to be as wide as possible, allowing for a column of xterms
-## down the right hand side.  However, I'd prefer a double-width Emacs to a
-## single-width Emacs and xterms.  If it's not going to work at all, a single
-## Emacs column will have to do.  Also, there's a strange thing with Emacs21
-## and the toolbar, so we add on some rows which are later mysteriously
-## subtracted.

+## We're going to make a single frame of Emacs, which will be automatically
+## divvied into columns; the rest of the space will be tiled with xterms.  If
+## we have multiple screens, then Emacs can have the first screen and we'll
+## fill the rest with terminals.  Otherwise, we'll try to have N columns of
+## Emacs, and N - 1 columns of xterms; if that doesn't work, we'll make do
+## with N - 2 columns of xterms.
+##
+## So, let W be the available width; let E and T be the widths of an Emacs
+## column (e_colwd) and terminal (t_wd), respectively, and let E0 be the
+## additive width of Emacs's existence (e_hextra).  If we have more than one
+## screen, then instead, let T be zero.  To start out, then, we let N = 1 +
+## floor((W - E - E0)/(E + T)).  If W - E0 - (N + 1) E - (N - 1)*T >= 0, then
