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