NAME

       dh_autoreconf - Call autoreconf -f -i and keep track of the changed files.

SYNOPSIS

       dh_autoreconf [debhelper options] [-Xitem] [--mode=mode] [program -- params]

DESCRIPTION

       dh_autoreconf is responsible for calling autoreconf and creating the files debian/autoreconf.before and debian/autoreconf.after which
       contain checksums of all files before/after the build. It is complemented by dh_autoreconf_clean which creates a list of all changed and
       added files and removes them.

       Please note that dh_autoreconf can only be run once. Thus, if you need to run multiple commands, use a script or similar. An example is
       given in dh-autoreconf(7).

FILES

       debian/autoreconf
	   This file can contain a list of directories. If present, dh_autoreconf will only scan the given directories for changes. If no special
	   command is given to dh_autoreconf, it will also forward the directory list to autoreconf which causes it to be run only on those sub
	   directories.

OPTIONS

       -Xitem --exclude=item
	   Exclude files that contain "item" anywhere in their filename from being checked for changes. This means that those files won't be
	   deleted by "dh_autoreconf_clean" even if there are changes. You may use this option multiple times to build up a list of things to
	   exclude.

	   Starting with version 3, the directories of common version control systems such as cvs, git, hg, svn, and bzr are excluded
	   automatically.

       --mode=mode
	   Change the way in which modifications to files are detected. The default mode is md5 for using MD5 checksums, but there is also
	   timesize for using the time of the last modification and the file size.

       --as-needed
	   Enable support for -Wl,--as-needed in all ltmain.sh files identical to the one of the libtool package. This only works in the MD5 mode
	   (the default one). The changes are reverted in dh_autoreconf_clean. You should not prevent LIBTOOLIZE from running with this, as it
	   only works correctly with libtoolize running.

       program -- params
	   Run the program given by program with the arguments given by params instead of autoreconf -f -i. If you need to run multiple commands,
	   put them in a script and pass the script instead (or add a target to debian/rules).

ENVIRONMENT

       For each tool executed by autoreconf(1), one can export a variable with the uppercase name of the tool to the specific program which shall
       be run, including true to prevent the tool in question from being run. The following example shows the beginning of a debian/rules for a
       package where automake 1.10 shall be run instead of the default automake version and libtoolize shall not be run:

	   #!/usr/bin/make -f
	   export AUTOMAKE = automake1.10
	   export LIBTOOLIZE = true
