+#!/usr/bin/perl
+# This program will print the RTLD and shared libraries paths for all
+# architectures.
+# It provides the list of directories that need to be kept up to date
+# in directories_to_merge() in convert-usrmerge and in setup_merged_usr()
+# in debootstrap when new architectures are added to Debian.
+#
+# The command line argument is the path to the debian/sysdeps/ directory
+# of the glibc package. It can be downloaded with the command:
+# git clone --depth=1 https://salsa.debian.org/glibc-team/glibc.git
