NAME

       dh_dwz - optimize DWARF debug information in ELF binaries via dwz

SYNOPSIS

       dh_dwz [debhelper options] [-Xitem] [-- params]

DESCRIPTION

       Caveat: This tool is experimental and may disappear or change behaviour without any
       notice.

       dh_dwz is a debhelper program that will optimize the (uncompressed) size of the DWARF
       debug information in ELF binaries.  It does so by running dwz(1) on all the ELF binaries
       in the package.

OPTIONS

       -Xitem, --exclude=item
           Exclude files that contain item anywhere in their filename from being stripped. You
           may use this option multiple times to build up a list of things to exclude.

       -- params
           Pass params to dwz(1) when it processes ELF binaries.  This is mostly useful for
           setting memory related parameters (e.g. -l and -L).

NOTES

       If the DEB_BUILD_OPTIONS environment variable contains nostrip, nothing will be stripped,
       in accordance with Debian policy (section 10.1 "Binaries").

       While this tool technically does not remove debug information from binaries, it is still
       skipped when the DEB_BUILD_OPTIONS environment variable contains nostrip.  This is because
       nostrip is often used to optimize build times (e.g. for "build and test"-cycles) rather
       than optimizing for size.
