dh_varnishabi - calculate the Varnish ABI dependencies

       Originally written by Chris  Boot  <bootc@debian.org>  as  dh_ppp(7),  then  Marco  d'Itri  <md@linux.it>
       modified it for Varnish.

perl v5.40.1                                       2025-03-18                                  DH_VARNISHABI(1p)

dh_varnishabi is a debhelper program that adds appropriate varnishabi-* dependencies on packages that
       build varnish modules.

       By default, a varnishabi-* entry is added to misc:Depends to ensure that packages which contain modules
       that are loaded by Varnish depend on an appropriate version of the varnish package.

       If --strict is specified, then a dependency on varnishabi-strict-* is added too.

       When building the varnish binary package the program will generate instead misc:Provides entries for
       varnishabi-* and varnishabi-strict-*.

       Substvars entries are only added if a Varnish module is detected in the build products, unless --force is
       specified.  Modules are detected by searching a package's build products for libraries installed in the
       Varnish vmods directory and containing a symbol named vmod_version.

       Please note there is a dh addon named varnishabi which can be used to automatically invoke dh_varnishabi
       for you.

       Note that this command is not idempotent. dh_prep(1) should be called between invocations of this command
       (with the same arguments). Otherwise, it may cause multiple instances of the same text to be added to the
       substition variables.

       Note  that  dh_varnishabi  should be run before dh_gencontrol.  The varnishabi sequence addon for dh does
       the right thing, this note is only relevant when you are calling dh_varnishabi manually.

--force
           Do not try to detect Varnish modules in the package, and always assume that a module is present. This
           will cause misc:Depends to always be populated.
