Environment set-up for IKEYCMD command-line interface

Set up the environment variables to use the IKEYCMD command-line interface as follows:

For Windows platforms, do the following:

Using the user interface or by modifying autoexec.bat on a command window, set/modify the PATH variable to include the location of the Java executable files:
```
set PATH=c:\Program Files\IBM\Host On-Demand\hod_jre\jre\bin;%PATH%;
```
Using the user interface or by modifying autoexec.bat on a command window, set/modify the CLASSPATH environment variable as follows:
```
set CLASSPATH=c:\Program Files\IBM\GSK7\classes\cfwk.zip;C:\
```
```
Program Files\IBM\GSK7\classes\gsk7cls.jar;%CLASSPATH%;
```

For AIX platforms:

First ensure that your xlC files (which constitute the run-time library for the standard AIX C++ compiler) meet one of the following requirements:

Use the following command to confirm your version:

lslpp -ha "xlC.aix*.rte"

(If your xlC fileset is outdated and you start the Host On-Demand ServiceManager with Certificate Management active, errors occur.)

Next make the following specifications:

Set your PATH to where your Java or JRE executable resides:
```
EXPORT PATH=/opt/IBM/Host On-Demand/hod_jre/jre/bin:$PATH
```

Set the following CLASSPATH environment variable:

EXPORT CLASSPATH=/usr/local/ibm/gsk7/classes/cfwk.zip:/
usr/local/ibm/gsk7/classes/gsk7cls.jar:$CLASSPATH

Once you have completed these steps, IKEYCMD should run from any directory. To run an IKEYCMD command, use the following syntax:

java com.ibm.gsk.ikeyman.ikeycmd <command>
