README file for CUNIT version 1.0. July 1995. 1) Why CUNIT? ============= There are several shareware programs available which also perform unit conversions. Why was CUNIT written? I have tried some of these programs and although they have all kinds of nice feeatures, I am not entirely comfortable with them - especially if you want to add units. One allows you to edit an entire table. This is unnecessary and it is very easy to currupt the table. I did not feel comfortable with this program and decided to write my own. With CUNIT you can easily add your own groups and units. It is very easy to use and you should have no problem if you are a Windows user. CUNIT also comes with a full set of units for chemical engineers - with values for R etc. Very handy for a quick conversions.... CUNIT is also FREE - no shareware fee is required and you may use it anywhere you wish. The program may also be freely distributed provided that you distribute the original version. You may also distribute your own CUNIT.DAT file if you have added new units - but in this case please mention that the file is NOT the original supplied with CUNIT. CUNIT is also a very small program and required very little space. The units supplied with it were taken from several text books and verified again. 2) Installation instructions ============================ First of all create the directory where you want the program to be installed, eg: md \cunit Now unzip the archive to this directory. Now go back to Windows and select the group in which you want the cunit icon to appear. Now from the File Manager menu do the following: Click on File, New, Program Item, OK. Type CUNIT and press TAB. Now enter the full path to the exe file, eg c:\cunit\cunit.exe. Now click on OK. The icon should now appear and you can run cunit! 3) Operating System =================== CUNIT was designed for Windows 3.1. It used only standard Windows API functions and should therefore execute with now problem on Windows 95, NT and OS/2. 4) FREEWARE =========== CUNIT may be freely used and copied by all who like it. No royalties or registration fees are charged. If you enjoy the program, it is all the reward I require. CUNIT is copyright by BJ van der Merwe. This means that you may NOT change the file CUNIT.EXE in any way. 5) About the author =================== CUNIT was written by BJ van der Merwe, a professional chemical engineer and author of several other programs. The program was carefully written to check for many potential situations and should run without a glitsch. The conversion factors used by CUNIT are stored in the file CUNIT.DAT. This is an ASCII file which may be edited if you so desire. Editing it is NOT recommended as CUNIT reads the entire file and overwrites it again every time you change any unit or group. If you must edit the file, do not change the format and use extreme CAUTION! Ideally you should make all changes using the program itself! 6) Networks =========== If you install CUNIT on a LAN and want users to be able to add units, they needs writing rights to the file CUNIT.DAT. For secutiry purposes it is recommended that you limit this access. 7) Disclaimer ============= Although every effort was made to ensure the absolute reliability of CUNIT, the final responsibility for using CUNIT rests with the USER. The author accepts no liability in any way. 8) Borland ========== CUNIT was written with the Borland C++ compiler version 4.0. It is an excellent development system and is highly recommended.
