&lindex()

The job of &lindex() is to traverse the filesystem or specified directories, then abstract out the keywords. &lindex() does this by making a list of directories that need to be indexed first, then it repeatedly calls do_directory and do_index to index these files. The following is a quick run-down on functions involved in &lindex().

• Name : sub parse_tag

• Name : sub do_directory
  Parameter : ($root_dir, $dir_name, $depth)
