-B<dh_auto_install> [S<I<debhelper options>>] [S<B<--> I<params>>]
+B<dh_auto_install> [S<I<build system options>>] [S<I<debhelper options>>] [S<B<--> I<params>>]
=head1 DESCRIPTION
dh_auto_install is a debhelper program that tries to automatically install
-built files. If there's a Makefile and it contains a "install" target,
-then this is done by running make (or MAKE, if the environment variable is
-set). If there is a setup.py or Build.PL, it is used.
-
-The files are installed into debian/<package>/ if there is only one binary
-package. In the multiple binary package case, the files are instead
-installed into debian/tmp/, and should be moved from there to the
-appropriate package build directory using L<dh_install(1)> or
-L<dh_movefiles(1)>.
+built files. It does so by running the appropriate command for the build
+system it detects the package uses. For example, if there's a Makefile and
+it contains a "install" target, then this is done by running make (or MAKE,
+if the environment variable is set). If there is a setup.py or Build.PL,
+it is used. Note that the Ant build system does not support installation,
+so dh_auto_install will not install files built using Ant.
+
+Unless --destdir option is specified, the files are installed into
+debian/<package>/ if there is only one binary package. In the multiple binary
+package case, the files are instead installed into debian/tmp/, and should be
+moved from there to the appropriate package build directory using
+L<dh_install(1)>.
DESTDIR is used to tell make where to install the files.
If the Makefile was generated by MakeMaker from a Makefile.PL, it will
