-#!/bin/bash
-#find-debuginfo.sh - automagically generate debug info and file list
-#for inclusion in an rpm spec file.
-#
-# Usage: find-debuginfo.sh [--strict-build-id] [-g] [-r] [-m]
-# [-o debugfiles.list]
-# [--run-dwz] [--dwz-low-mem-die-limit N]
-# [--dwz-max-die-limit N]
-# [[-l filelist]... [-p 'pattern'] -o debuginfo.list]
-# [builddir]
-#
-# The -g flag says to use strip -g instead of full strip on DSOs or EXEs.
-# The --strict-build-id flag says to exit with failure status if
-# any ELF binary processed fails to contain a build-id note.
-# The -r flag says to use eu-strip --reloc-debug-sections.
-#
-# A single -o switch before any -l or -p switches simply renames
-# the primary output file from debugfiles.list to something else.
-# A -o switch that follows a -p switch or some -l switches produces
-# an additional output file with the debuginfo for the files in
-# the -l filelist file, or whose names match the -p pattern.
-# The -p argument is an grep -E -style regexp matching the a file name,
-# and must not use anchors (^ or $).
-#
-# The --run-dwz flag instructs find-debuginfo.sh to run the dwz utility
-# if available, and --dwz-low-mem-die-limit and --dwz-max-die-limit
-# provide detailed limits. See dwz(1) -l and -L option for details.
-#
-# All file names in switches are relative to builddir (. if not given).
-#
-
-# With -g arg, pass it to strip on libraries or executables.
-strip_g=false

-# with -r arg, pass --reloc-debug-sections to eu-strip.
