=head1 NAME
dh_installman - install man pages into package build directories
=cut
use strict;
use File::Find;
use Debian::Debhelper::Dh_Lib;
=head1 SYNOPSIS
dh_installman [debhelper options] [manpage ...]
=head1 DESCRIPTION
dh_installman is a debhelper program that is responsible for installing
man pages into the correct locations in package build directories. You tell
it what man pages go in your package(s), and it figures out where to
install them based on the section field in their .TH line and their filename
extention.
Any man page filenames specified as parameters will be installed into the
first package dh_installman is told to act on. By default, this is the
first binary package in debian/control, but if you use -p, -i, or -a flags,
it will be the first package specified by those flags.
Files named debian/package.manpages can list other man pages to be
installed.
After the man page installation step, dh_installman will check to see if
any of the man pages in the temporary directories of any of the packages it
is acting on contain ".so" links. If so, it changes them to symlinks.
=head1 OPTIONS
=over 4
=item B<-A>, B<--all>
Install all files specified by command line parameters in ALL packages
acted on.
=item I<manpage ...>
Install these man pages into the first package acted on. (Or in all
packages if -A is specified).
=back
=head1 NOTES
An older version of this program, L<dh_installmanpages(1)>, is still used
by some packages, and so is still included in debhelper.
It is, however, deprecated, due to its counterintuitive and inconsistent
interface. Use this program instead.
