=head1 SYNOPSIS
B<dh_auto_install> [S<I<build system options>>] [S<I<debhelper options>>] [S<B<--> I<params>>]
=head1 DESCRIPTION
B<dh_auto_install> is a debhelper program that tries to automatically install
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 F<Makefile> and
it contains a B<install> target, then this is done by running B<make> (or B<MAKE>,
if the environment variable is set). If there is a F<setup.py> or F<Build.PL>,
it is used. Note that the Ant build system does not support installation,
so B<dh_auto_install> will not install files built using Ant.
In compat 15 or later, B<dh_auto_install> will use F<debian/tmp> as the default
B<--destdir> and should be moved from there to the appropriate package build
directory using L<dh_install(1)> or similar tools. Though if the B<single-binary>
addon for L<dh(1)> is activated, then it will pass an explicit
B<< --destdir=debian/I<package>/ >> to B<dh_auto_install>.
For earlier compat levels then unless B<--destdir> option is
specified, the files are installed into debian/I<package>/ if there is only one
binary package. In the multiple binary package case, the files are instead
installed into F<debian/tmp/>, and should be moved from there to the
appropriate package build directory using L<dh_install(1)> or similar tools.
B<DESTDIR> is used to tell make where to install the files.
If the Makefile was generated by MakeMaker from a F<Makefile.PL>, it will
automatically set B<PREFIX=/usr> too, since such Makefiles need that.
This is intended to work for about 90% of packages. If it doesn't work, or
tries to use the wrong install target, you're encouraged to skip using
B<dh_auto_install> at all, and just run make install manually.
=head1 OPTIONS
See L<debhelper(7)/B<BUILD SYSTEM OPTIONS>> for a list of common build
system selection and control options.
=over 4
=item B<--destdir=>I<directory>
Install files into the specified I<directory>. If this option is not specified,
destination directory is determined automatically as described in the
L</B<DESCRIPTION>> section.
=item B<--> I<params>
Pass I<params> to the program that is run, after the parameters that
B<dh_auto_install> usually passes.
