3.4 Options for Programs that Walk File and Directory Trees.

The programs mkid and xtokid accept the names of files and directories on the command line. Files are scanned if there is a scanner available and enabled for the file's source language. Directories are recursively descended, searching for files whose names match the rules listed in the language map file (see Language map).

The following option controls the file tree walker:

`-p names'

`--prune=names'

One or more file or directory names may appear in names. The file tree walker will stop short at these files and directories and their contents will not be scanned.
