# The idea behind this is storing changes produced by autoreconf as a
12
# separate patch on quilt stack (on top of stack actually).
13
# The only usable target here is 'autoreconf`. Other targets are not
14
# supposed to be called directly. DO NOT invoke them, unless you know what
16
# The autoreconf target will check if files with names in $(RECONF_CHECKFILES)
17
# were changed during patching (from upstream version or from previously
18
# autoreconfed version) and call actual autoreconfing if they were.
19
# The actual autoreconfing target (doautoreconf) WILL FAIL after
20
# calling autoreconf and pushing changes into quilt stack by design. It
21
# should never be invoked by automatic build process.
22
# The proposed use is adding autoreconf into clean's prerequisites before
25
# + clean: autoreconf xsfclean
26
# This will ensure it is called when you build package with dpkg-buildpackage.
28
# This dir will be used for producing diff of autoreconfed tree
