You may even include the source code, modified or unmodified
in free/commercial open source/proprietary programs that you write and distribute.
May be used freely for any purpose but military.

All Java jars and source code are included.

----

Prerequisites:

This program runs under any OS,
(e.g. Win2K/XP/Vista/W7x86/W7-64/OSX/Linux/Solaris/AIX...) so long as you have
<><> Java version 1.1 <><> or later installed (32-bit or 64-bit Java).
See http://mindprod.com/jgloss/installingjava.html for details.

----

Installing on a PC:

Download source and compiled class files to run on your own machine as an application.
First install a recent Java JDK or JVM.
See http://mindprod.com/jgloss/installingjava.html.
To install, extract the zip download with WinZip
(or similar unzip utility) into any directory you please,
often J:\ --  ticking off the "use folder names" option.
To run as an application,type:
java -ea -jar J:\com\mindprod\screws\screws.jar {put any parms here}

adjusting as necessary to account for where the jar file is.

----

Installing on a MacIntosh:

Use Safari to download source and compiled class files to run on your own machine as an application.
Safari will automatically unpack the zip into ~/Downloads (version 10.5)
[or on the Desktop (version 10.4 and earlier)].
First install a recent Java JDK or JVM.
See http://mindprod.com/jgloss/installingjava.html.
You may optionally move the download tree to a permanent home.
I don't have a MacIntosh, just a PC, so I can't test my Java programs for Mac compatibility.
In theory they should work without problems, but in practice that does not always happen.
If you have problems please, let me know, preferably with screenshots and complete verbatim error messages.
To run as an application, without parameters, just double click the jar file.

To run as an application with parameters, in bash shell type:
open Terminal.app
cd ~/Desktop
java -ea -jar com/mindprod/screws/screws.jar {put any parms here}

adjusting as necessary to account for where the jar file is.

----

Rebuilding:

The zip already contains the necessary class and jar files, so unless you modify
the program, there is no need to recompile the source or rebuild the jar.
Configure.java basedir="E:/" in rebuild.xml to the drive where your files are.
Use ANT and rebuild.xml, not build.xml, to recompile and recreate the jar.

----

Use:

CMP Screws and Screwdrivers draws eight types of screw
heads. It is a teaching example for how to use Java Canvas,
fillRect, fillOval, fillPoly and AffineTransform to draw.

Java source is included for you to cannibalise.

It draws 8 types of screw heads.

see http://mindprod.com/bgloss/cables.html#SCREWDRIVERS
for more information on the cosmic significance
of the output.

To run as an application, type:

java -jar C:\com\mindprod\screws\screws.jar

adjusting as necessary to account for where the jar file is.
