# A simple utility for watching a given directory for temporary files,
# directories, etc.  Primarily used to casually discover applications that
# are vulnerable to race conditions or symlink foo.
#
# The irony?  There is no mktemp that creates temporary directories, so
# here in code that is designed to point out temporary directory/file
# issues, I have to reinvent the wheel.
#
# Temporary files -- yer doing it wrong.
