ppwhelp starts up the PPW Java GUI help system, which lets you browse all available documentation for PPW.
To invoke ppwhelp, use the following syntax:
ppwhelp does not have any command-line options.
Note that this command requires a Java installation to work properly. If you do not have a Java installation available, please install the GUI on your workstation, or see the PPW manual section entitled `Installing PPW' for more options.
All documentation available through ppwhelp is also available on the PPW website at http://ppw.hcs.ufl.edu/.
If you did not configure PPW to use a Java installation at build time, or would like to override which version of Java PPW uses to start the GUI, you may set the JAVA_CMD environment variable to the full path of a Java interpreter.
