   Two useful functions that are not in 'awk' are 'chdir()' (so that an
'awk' program can change its directory) and 'stat()' (so that an 'awk'
program can gather information about a file).  In order to illustrate
the API in action, this minor node implements these functions for 'gawk'
in an extension.
