=head1 SYNOPSIS

B<dh_installdeb> [S<I<debhelper options>>]

=head1 DESCRIPTION

B<dh_installdeb> is a debhelper program that is responsible for installing
files into the F<DEBIAN> directories in package build directories with the
correct permissions.

=head1 FILES

=over 4

=item I<package>.postinst

=item I<package>.preinst

=item I<package>.postrm

=item I<package>.prerm

These maintainer scripts are installed into the F<DEBIAN> directory.

Inside the scripts, the token B<#DEBHELPER#> is replaced with
shell script snippets generated by other debhelper commands.

=item I<package>.triggers

=item I<package>.shlibs

These control files are installed into the F<DEBIAN> directory.

Note that I<package>.shlibs is only installed in compat level 9 and
earlier.  In compat 10, please use L<dh_makeshlibs(1)>.

=item I<package>.conffiles

This control file will be installed into the F<DEBIAN> directory.

In v3 compatibility mode and higher, all files in the F<etc/> directory in a
package will automatically be flagged as conffiles by this program, so
there is no need to list them manually here.

=item I<package>.maintscript

Lines in this file correspond to L<dpkg-maintscript-helper(1)> commands and
parameters.  Any shell metacharacters will be escaped, so arbitrary shell
code cannot be inserted here.  For example, a line such as C<mv_conffile
/etc/oldconffile /etc/newconffile> will insert maintainer script snippets
into all maintainer scripts sufficient to move that conffile.
