Class ExeName

java.lang.Object
  ccs.utils.ExeName

public class ExeName
extends java.lang.Object

Executables have different names on different platforms. E.g. "jstart" on linux will be "jstart.exe" on win32. We might in future institute some kind of convention to decorate executable names to distinguish the various flavours of unix / linux / solaris / etc. Use this class to translate.
