README file needs update

[User8192]

• The links in the README file for obtaining Java Runtime Environment are old; sun.com has been absorbed into oracle.com.
• Various style, grammar, punctuation and syntax corrections needed.

CURRENT TEXT: (as of version 4597)

This is a readme.txt to the Java OpenStreetMap Editor


Install Notes
-------------

To run JOSM, you need:

* The jar file (e.g. josm.jar)
* The latest Java Runtime Environment 1.6. 


How to get Java
---------------

You need at least Version 1.6 (called Java6). 

Microsoft Windows people should just visit java.sun.com and
download the latest Java6 executable. 

To get Java under linux, either download the environment 
directly from Sun at http://java.sun.com (there is a linux 
binary installer which you have to execute from a console) or
use the mechanisms of your distributions packaging system.

How to launch
-------------

Microsoft Windows people launch by double clicking on the jar file.
If this does not help, open a command shell and type 
"java -jar josm-latest.jar" in the directory that holds the file.
(Please replace josm-latest.jar with the name of your jar file, if
you don't used the latest version.)

Under Linux open a shell, go to the file directory and type
"java -jar josm-latest.jar" to launch. If this don't help, try to set
your JAVA_HOME variable to the java location (the root location, not
the bin)

MacOS people just click on the jar-file.


How to get the Source
---------------------

Download it directly from the subversion at 
https://josm.openstreetmap.de/svn/trunk. To use the command line
subverion client, type

svn co https://josm.openstreetmap.de/svn/trunk

SUGGESTED REVISED TEXT:

Supplemental information for JOSM -- the Java OpenStreetMap Editor


Installation notes
------------------
To run JOSM, you need:

* The JOSM .jar file, e.g., josm-tested.jar or josm-latest.jar
* Java Runtime Environment (JRE) 1.6, or later. 


How to get Java Runtime Environment
-----------------------------------
You need JRE Version 1.6 (also called Java6), or later. 

Microsoft Windows users should visit 
http://www.oracle.com/technetwork/java/index.html 
and download the latest Java6 executable for Windows systems.

Linux users should visit http://www.oracle.com/technetwork/java/index.html
There is a Linux binary installer, which you must execute from a console, or 
use the mechanism of your distribution's packaging system.


How to launch
-------------
Microsoft Windows users launch by double-clicking on the .jar file.
If this does not work, open a command shell and type "java -jar josm-latest.jar" 
in the directory that holds the file. (Please replace josm-latest.jar with the 
name of your .jar file, if you aren't using the latest version.)

Under Linux, open a shell, go to the file directory and type
"java -jar josm-latest.jar" to launch. If this does not work, try to set
your JAVA_HOME variable to the java executable location (the root location, 
not the bin).

MacOS users just click on the .jar file icon.


How to get the source code
