========================================================================

Bicycle Ride Calorie Calculator was originally an OS/2 PM 
program that I ported to Linux using the FLTK widget library.
The program calculates the number of calories expended on a bicycle 
ride and is based on an article in the May 1989 issue of Bicycling
Magazine, pp. 100-103.  It provides a good estimate of the
number of calories burned based on time, distance, rider weight,
wind speed and direction, drafting, and climbing.  It is not 
meant to be a completely accurate calculator and playing with
the input values will reveal that the equations break down for
very small and very large average speed values.  Calorie
expediture values seem very reasonable for average speeds
between 5 and 30 mph.

The interface is very straight-forward--click on the appropriate
radio buttons and set the text field values appropriate to your
ride and press the Calculate button.  The results appear at the
bottom of the screen.  

The program defaults to English units, but can toggle and convert
between English and Metric via the Units menu on the menubar.

In order to compile the program, you must have the FLTK library
and header files installed.  The most recent version of Fltk
can be found on the FLTK Home Page at http://fltk.easysw.com.

If you use this software, please email me and let me know.  I
am curious to see how widely used it becomes.  I am also eager
to hear any user questions/comments/suggestions.  Feel free 
to email me at kondrag@geocities.com.

This edition matches the capabilities found in v1.01 REXX version
for OS/2.  The version will likely add support for saving a
default starting state for the program's fields and units.  I'd 
also like to add some additional cycling-related calculations,
probably through a tabbed interface.  A spoke length calculator
and gear calculator are two I can think of offhand.  If anyone has
any further suggestions, please let me know!

Enjoy!
