-=head1 SYNOPSIS
-
- dh_link [debhelper options] [-A] [source destination ...]
-
-=head1 DESCRIPTION
-
-dh_link is a debhelper program that creates symlinks in package build
-directories.
-
-dh_link accepts a list of pairs of source and destination files. The source
-files are the already existing files that will be symlinked from. The
-destination files are the symlinks that will be created. There B<must> be
-an equal number of source and destination files specified.
-
-The list can be specified in two ways. A file named debian/package.links
-can list pairs of files. If you use this file, you should put each pair
-of files on its own line, and separate the files within the pair with
-whitespace. Also, pairs of files can be specified as parameters - these
-pairs will only be created in the package build directory of the first
-package dh_link 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.
-
-Be sure you B<do> specify the full filename to both the source and
-destination files (unlike you would do if you were using something like
-L<ln(1)>).
-
-dh_link will generate symlinks that comply with debian policy - absolute
-when policy says they should be absolute, and relative links with as short
-a path as possible. It will also create any subdirectories it needs to to put
-the symlinks in.
-
-=head1 OPTIONS
-
-=over 4
-
-=item B<-A>, B<--all>
-
-Create any links specified by command line parameters in ALL packages
-acted on, not just the first.
-
-=item I<source destination ...>
-
-Create a file named "destination" as a link to a file named "source". Do
-this in the package build directory of the first package acted on.
-(Or in all packages if -A is specified.)

-=head1 EXAMPLES
-
- dh_link usr/share/man/man1/foo.1 usr/share/man/man1/bar.1
-
-Make bar.1 be a symlink to foo.1
-
- dh_link var/lib/foo usr/lib/foo \
- usr/X11R6/man/man1/foo.1x usr/share/man/man1/bar.1
-
-Make /usr/lib/foo/ be a link to /var/lib/foo/, and bar.1 be a symlink to
-the X man page foo.1x
