First things first. Because I use =org-babel= and literate programming

|

possible. For that reason, I want Emacs to put all of its generated

fluff into a separate file that is actually outside the Emacs

directory.

startup messages, the splash screen, tool bar, and tooltips.

** Spelling
|

|

Spelling is important (I'm terrible at spelling). This block configures
|

=ispell=. It relies on an external dictionary program; first it will check
|
||||
to see if =aspell= is available, and if so, set it as the default spell
|
||||
checking program. If that's not found, it will search for =hunspell= and set
|
||||
that. If neither is found, oh well, no spell checking program for us.

=scroll-step= controls the number of lines that the window will scroll

||||
will jump you so that the cursor is centered (vertically) after
|
||||
scrolling. I really don't like this behavior, so I set it to =1= so the
|
||||
window will only move by a single line.
