{{{start up files
loads in a startup file called emacs_rc from directory pointed at by
emacs$dir
My default emacs_rc loads in <emacs$dir>.ue_mac_rc, which defines
various macros, not all of which are used.
Also, all my key bindings are established - customise freely.
It also defines the fold-marks - what comment characters to use
for various file types.
File type is recognised _either_ by a trailing _c, for example, or
a leading c.
It also establishes a read-hook - a subroutine called every time a
file is opened - for example, this sets cmode for _c and _h

{{{u-emacs survival course
META means escape
^X means ctrl-x
META and ^X are the first part of two-keystroke sequences.
^X-^C (ctrl-x then ctrl-c) is exit
^X-^S is save
M-Z (escape then z) is save-and-exit
^S is search
^X-? is describe key - press any key or combination, and it will
tell you what it does.
META-^X gives a : prompt at the bottom line
: help - loads in a help file ( <emacs$dir:emacs_hlp )
: describe-bindings opens a window with all key bindings listed
: describe-variables opens a window showing all variables and pseudo-vars

{{{recompiling
All config opts (should) go in h.estruct
I dont think I bothered putting in mouse support, but it can be done.
In fact, there are many things I didn't bother doing.
I changed the screen update to be like TWIN - it updates from cursor
posn down, then from cursor posn up.
I fixed a bug that sems to have been in u-emacs for years, concerning
smooth-scrolling and small files (between one and two screenfuls long)

Erm - I'm bored now - write if you need anything else
