# Audit the fpath to assure that it contains all the directories needed by
# the completion system, and that those directories are at least unlikely
# to contain dangerous files.  This is far from perfect, as the modes or
# ownership of files or directories might change between the time of the
# audit and the time the function is executed.

# This function is designed to be called from compinit, which assumes that
# it is in the same directory, i.e., it can be autoloaded from the initial
# fpath as compinit was.  Most local parameter names in this function must
# therefore be the same as those used in compinit.
