##  Source packaging support


##  Debian packaging support

##  Adding files such as debian/rules.in and debian/control.in to the
##  list of AC_CONFIG_FILES does not work as one would expect.  Files
##  listed become candidates for removal by `make distclean`.
##
##  With the regular Debian build machinery doing exactly that at the
##  very start of just about any build, said build machinery will, as
##  a result, have understandable trouble finding usable debian/rules
##  and debian/control files.
