=head1 SYNOPSIS

B<dh_installdirs> [S<I<debhelper options>>] [B<-A>] [B<--sourcedir=>I<dir>] [B<--create-in-sourcedir>] [S<I<dir> ...>]

=head1 DESCRIPTION

B<dh_installdirs> is a debhelper program that is responsible for creating
subdirectories in package build directories.

Many packages can get away with omitting the call to B<dh_installdirs>
completely.  Notably, other B<dh_*> commands are expected to create
directories as needed.

=head1 FILES

=over 4

=item debian/I<package>.dirs

Lists directories to be created in I<package>.

Generally, there is no need to list directories created by the
upstream build system or directories needed by other B<debhelper>
commands.

Supports substitution variables in compat 13 and later as
documented in L<debhelper(7)>.

=head1 OPTIONS

=over 4

=item B<-A>, B<--all>

Create any directories specified by command line parameters in ALL packages
acted on, not just the first.

=item B<--create-in-sourcedir>, B<--no-create-in-sourcedir>

Whether to create the specified directories in the source directory
(usually F<debian/tmp>) I<in addition to> in the package build directory
(usually F<< debian/I<package> >>).

The default is B<--no-create-in-sourcedir>.

=item B<--sourcedir=>I<dir>

Consider I<dir> the source directory for the packages acted on instead
of the default (which is usually F<debian/tmp>).

Please note that this option is dependent on the
B<--create-in-sourcedir> option (when B<--no-create-in-sourcedir> is
in effect, this option does nothing in B<dh_installdirs>).

=item I<dir> ...

Create these directories in the package build directory of the first
package acted on. (Or in all packages if B<-A> is specified.)

		# specified.
