       debhelper-obsolete-compat - List of no longer supported compat levels

       This document contains the upgrade guidelines from all compat levels
       which are no longer supported.  Accordingly it is mostly for historical
       purposes and to assist people upgrading from a non-supported compat
       level to a supported level.

       For upgrades from supported compat levels, please see debhelper(7).

       The following is the list of now obsolete compat levels and their

       v1  This is the original debhelper compatibility level, and so it is
           the default one. In this mode, debhelper will use debian/tmp as the
           package tree directory for the first binary package listed in the
           control file, while using debian/package for all other packages
           listed in the control file.

           This mode is deprecated.

       v2  In this mode, debhelper will consistently use debian/package as the
           package tree directory for every package that is built.

           This mode is deprecated.

       v3  This mode works like v2, with the following additions:

           -       Debhelper config files support globbing via * and ?, when
                   appropriate. To turn this off and use those characters raw,
                   just prefix with a backslash.

           -       dh_makeshlibs makes the postinst and postrm scripts call

           -       Every file in etc/ is automatically flagged as a conffile
                   by dh_installdeb.

           This mode is deprecated.

       v4  Changes from v3 are:

           -       dh_makeshlibs -V will not include the Debian part of the
                   version number in the generated dependency line in the
                   shlibs file.

           -       You are encouraged to put the new ${misc:Depends} into
                   debian/control to supplement the ${shlibs:Depends} field.

           -       dh_fixperms will make all files in bin/ directories and in
                   etc/init.d executable.

           -       dh_link will correct existing links to conform with policy.

           This mode is deprecated.

       v5  This is the lowest supported compatibility level.

           Changes from v4 are:

           -       Comments are ignored in debhelper config files.

           -       dh_strip --dbg-package now specifies the name of a package
                   to put debugging symbols in, not the packages to take the
                   symbols from.

           -       dh_installdocs skips installing empty files.

           -       dh_install errors out if wildcards expand to nothing.
