// Breadcrumb trail based on directory names
// Nick Negulescu, nnegulescu@fs.fed.us
// 07-10-2002 v. 1.5
// base = base URL of site w/out last "/" slash. e.g. http://me.com http://me.com/dir
// delStr = delimiter string
// defIndx = directory index page (e.g. 'index'/Apache 'Default'/IIS)
// cStyle = style sheet property for links
// tStyle = style sheet property for title page
// dStyle = style sheet property for delimiter string
// nl = 0, 1 (false, true) for printing page title on new line
// NOTE: lines commented out are for debugging purposes
// call the function in HTML by:
// <script language="JavaScript">
//  breadCrumbs("Site Name", "BASE.URL", "delimiter", "index", "style", "style", "style", "0");
/* </script> */
// 1.5: Mozilla/Netscape 6.0 fixes, takes site name as parameter
// 1.4: BC parses URL and capitalizes after "_" underscores
// 1.2: same as 1.1, minus the debugging info
// 1.0: Adopted based on code by PAUL DAVIS
