		How to use the -mf slide macros
			by Rob Kolstad

The RBK slide-making macros (aka foil-making macros) are so easy to use
it's almost unbelievable.  There are only a very small number of macros.
We'll cover each of them here.

Overview

The macros have fixed sizes, fonts, and formats for the slides.  I believe
that a fixed format allows the audience to concentrate on the information
rather than the boilerplate of the slide itself.  Each slide has a
pleasant border with rounded corners and the current date in the lower
left corner.  Optionally, you can put a small phrase centered in the
bottom line of the border (e.g., your initials and/or a slide number).
Page numbers appear below the border on the right side of the slide.

You'll have to figure out how to do landscape style output for 
site.  I'll call the program `troff' and assume that -L does landscape
mode.

Print slides using the following command (or its equivalent):
	% troff -L foilmacros file.with.slides

Don't forget the -L on the troff commands as the slides are
printed rotated (i.e., in landscape mode).

Using the macros

Include
    .au "author information"	\" or anything else
if you wish to have some information printed in the middle of the
lower line.  I personally do this:
    .au  "RBK \- FileName"
at the front of EACH file I use for slides.  I generally separate
slides into many many files for easy editing and reprinting.  You may
choose a different technique.

It's easy to print text on slides.  Lines can be centered (.c), left
justified (.1), left justified with a solid round bullet (.2), left
justified with a hollow round bullet (.3), or left justified with a hollow
square bullet (.4).  I never use the .1 (unbulleted) headings.  I like
bullets.

To specify a line, choose one of two formats:

	.c "Line to be centered"

or

	.c
	Bunch of text to be centered	\" one line only for .c

I find the second way much easier to type and a bit easier to
read/debug.  Both schemes create the same results.  The .c
macro takes only a single line to be centered if invoked without the
text.  The other macros work just find with multiple lines of text.
I like to start my slides with a .c line -- but always put a blank
line before it so it looks nice on the page.

You must enter your own page breaks:
	.bp
between each slide.

Here's a typical example of a slide:

					<--- blank line
	.c
	This is an example slide	<--- title of this slide
					<--- blank line
	.2
	This is the important first bullet
	.3
	This is a semi-important sub-bullet
	.3
	This is a semi-important sub-bullet
					<--- blank line
	.2
	This is the important second bullet
	.3
	This is a semi-important sub-bullet
	.3
	This is a semi-important sub-bullet
	.bp				<--- to next page

Good luck!
