                             What Is Shareware?
                             ------------------

  There are many ways a software author can release his program to the public.

  You are all probably familiar with RETAIL software.  This is the software you
  purchase at a store or over the Internet.  RETAIL software offers you no way to
  actually try the software before you try it.  You have to depend on the
  description on the box, reviews by others who may not have the same needs as you
  or friends/associates wbo have used the software.  All that advertising and
  marketing has a cost and that cost increases the cost of the software.

  PUBLIC DOMAIN software is software that the author has released to the public.
  That means it is not copyrighted and anyone can use it any fashion.  Sometimes
  PUBLIC DOMAIN software will contain the source code.  In that case, you are
  free to change it to your heart's content with no thought as to what the orginal
  author may think.

  FREEWARE is somewhat similar to public domain software.  However, the big
  difference is that with FREEWARE, the original author retains the copyright.
  This allows the author to retain some level of control over the software.
  Usage of the software is free.

  DEMOWARE is usually retail software that will only "show" you how the software
  works.  Usage of the software is severely limited if available at all.

  CRIPPLEWARE is typically a retail software software package that has key features,
  such as saving to a file or printing, "crippled" or disabled.  This allows you to
  use the program but not to use some important functions.

  SHAREWARE, though, is different from all the above.  SHAREWARE allows you to fully
  use the program.  All functions are available with none disabled.  As with Freeware,
  the original author retains the copyright and both the ability and the responsibility
  to maintain the program.

  As a SHAREWARE user, your responsibility is to use the program for the amount of
  time designated by the author and, if you find it useful, register with the author.
  Yes, that means sending the author money.  There are usually benefits attached to
  registering your copy of a shareware program.  These may vary according to the
  program and the author.
  

The first file, PERFMISC.EXE©, is a "compendium" of formulas, most of which are already on the website. This current version is 01.3.0. This program will be updated periodically as more formulas are added.

This program was written in freeBASIC and as such, it is a Windows console program or a DOS 32 bit program. Please read the "README.TXT" file included with the program. It will unzip to C:\PERFMISC automatically. Please note that the help file included with this program only works in Windows.

The second file is called PERFMISC_W.EXE©, version 1.3.0. It is a full Windows version of the above console program.

Once you have installed the Windows program, if you go to the main subdirectory, C:\Program Files\Keller Racing\PerfMisc, you will see a file like pmbwx13x.exe. Here is the "code" for our files: The "PM" stands for "Performance Miscellaneous". The next "B" stands for the language the program was written in, in this case a dialect of BASIC, LibertyBASIC. The following "W" means it is a Windows program. If you downloaded the PERFMISC.EXE© file, when you unzip it and go the same subdirectory, you will see the file, pmbcx13x.exe. In this case, the the "PM" stands for Performance Miscellaneous, the next "B" stands for a different BASIC dialect, in this case freeBASIC and the "C" stands for console or DOS program.

The "X"'s will be the version number eventually. Our version numbers will be in the form XX.X.X. The first two X's are for the version number. The next X will be for temporary upgrades and the final X will be for bug fixes for that version.

The second program is PERFORMANCE TUNER©. This program allows the user to input current atmospheric conditions and not only tune the carb but also predict performance based on the current atmospheric conditions. This program also comes in two versions, a DOS/Console version and a Windows version. These programs are currently version 01.0.0 (see above for explanation of version code). We would appreciate any feedback that users can give us.

The next programs due down the pipeline are an analysis program and a drag race simulation. Please stop by later for these programs.
