-# This shell script produces a header file fragment that defines
-# SYSROOT_SUFFIX_SPEC.  It assumes that the sysroots will have the same
-# structure and names used by the multilibs.
-
-# Invocation:
-#   print-sysroot-suffix.sh \
-#          MULTILIB_OSDIRNAMES \
-#          MULTILIB_OPTIONS \
-#          MULTILIB_MATCHES \
-#      > t-sysroot-suffix.h
-
-# The three options exactly correspond to the variables of the same
-# names defined in the tmake_file fragments.
-
-# Example:
-#   sh ./gcc/config/print-sysroot-suffix.sh "a=A" "a b/c/d" ""
-# =>
-#   #undef SYSROOT_SUFFIX_SPEC
-#   #define SYSROOT_SUFFIX_SPEC "" \
-#   "%{a:" \
-#     "%{b:A/b/;" \
-#     "c:A/c/;" \
-#     "d:A/d/;" \
-#     ":A/};" \
-#   ":}"
-
-# The script uses temporary subscripts in order to permit a recursive
-# algorithm without the use of functions.
