/** Get the value to display for the bsh interactive prompt. This command checks for the variable bsh.prompt and uses it if set. else returns "bsh % "

Remember that you can override bsh commands simply by defining the method in your namespace. e.g. the following method displays the current working directory in your prompt:

	String getBshPrompt() {
		return bsh.cwd + " % ";
	}
	
*/ String getBshPrompt() { if ( bsh != void && bsh.prompt != void ) return bsh.prompt; else return "bsh % "; }
