-=head1 NAME
-
-B<makefile> - make (Makefile)
-
-=head1 SYNOPSIS
-
-B<dh_auto_*> [B<--buildsystem>=I<makefile>] ...
-
-=head1 DESCRIPTION
-
-Makefile based projects use C<make> to control build process. C<make> utility
-is the most popular tool on *NIX for building & installing packages from
-source. It is also a basis for most other popular build systems. For example,
-GNU Autoconf (autoconf) or CMake (cmake) generate F<Makefile>s during I<configure>
-step and leave the rest of build process for C<make> to handle.
-
-=head1 DH_AUTO NOTES
-
-Since C<make> itself does not strictly define standard target names, a couple
-of the most popular targets are tried for each building step. Whichever first
-of them is discovered to exist, it is run. If neither of the tried targets
-exist in the actual, the building step is assumed to have completed
-successfully. However, if executed C<make> target fails, the respective dh_auto
-program will fail too.
-
-If MAKE environment variable is set, its value is executed rather than default
-C<make> command.
-
-Both in source (default) and out of source tree building modes are supported.
-Either F<Makefile>, F<makefile> or F<GNUmakefile> file should be present in the
-build directory for this debhelper build system to work.
