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.
