// javascript menu builder
// tkennedy@lycos-inc.com
// versions:
// 0.5: regexp tomfoolery
// 1.0: replication of perl script to javascript
// 1.1: regexp tomfoolery removed -- logic too clunky and cumbersome
// 1.2: angelfire specific menu seperation code added
// 1.3: af specific code generalized for use on other sites without modification to menu builde code, only configuration file
// 1.4: added code for creation of sub menu
// notes:
// this script must be used in conjunction with a site specific datafile in javascript format
