# This is a perl rewrite of the flatten subsection of
# the slink_cd script.
#flatten: expects a list of files as standard
# input. leaves symlinks into the current tree alone,
# changes other links. Needs the directories of the mirror
# and the non-us mirror.
# syntax: "cat <files > | flatten mirror non-us debug_level"
