/**
	Return directory portion of path based on the system default file separator.
	Note: you should probably use pathToFile() to localize the path relative
	to BeanShell's working directory and then file.getAbsolutePath() to get
	back to a system localized string.
	
	
	Example: to change to the directory that contains the script we're 
	currently executing:

	
	// Change to the directory containing this script
	path=pathToFile( getSourceFileInfo() ).getAbsolutePath();
	cd( dirname( path ) );
	
*/

bsh.help.cd = "usage: dirname( path )";

String dirname( String pathname ) 
{
	String dirName = ".";
	// Normalize '/' to local file separator before work.
	int i = pathname.replace('/', File.separatorChar ).lastIndexOf( 
		File.separator );
    if ( i != -1 )
		dirName = pathname.substring(0, i);

	return dirName;
