=head1 SYNOPSIS

B<dh_installinfo> [S<I<debhelper options>>] [B<-A>] [S<I<file> ...>]

=head1 DESCRIPTION

B<dh_installinfo> is a debhelper program that is responsible for installing
info files into F<usr/share/info> in the package build directory.

From debhelper compatibility level 11 on, B<dh_install> will fall back to
looking in F<debian/tmp> for files, if it does not find them in the current
directory (or wherever you've told it to look using B<--sourcedir>).

=head1 FILES

=over 4

=item debian/I<package>.info

List info files to be installed.

=back

=head1 OPTIONS

=over 4

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

Install all files specified by command line parameters in ALL packages
acted on.

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

Look in the specified directory for files to be installed.  This option
requires compat 11 or later (it is silently ignored in compat 10 or earlier).

Note that this is not the same as the B<--sourcedirectory> option used
by the B<dh_auto_>I<*> commands. You rarely need to use this option, since
B<dh_installinfo> automatically looks for files in F<debian/tmp> in debhelper
compatibility level 11 and above.

=item I<file> ...

Install these info files into the first package acted on. (Or in
all packages if B<-A> is specified).
