=head1 NAME
dh_installdocs - install documentation into package build directories
=cut
use strict;
use Debian::Debhelper::Dh_Lib;
=head1 SYNOPSIS
B<dh_installdocs> [S<I<debhelper options>>] [B<-A>] [B<-n>] [B<-X>I<item>] [S<I<file ...>>]
=head1 DESCRIPTION
dh_installdocs is a debhelper program that is responsible for installing
documentation into usr/share/doc/package in package build directories.
dh_installdocs automatically installs debian/copyright if it exists. If
dh_installdocs is acting on multiple packages, debian/copyright files will be
installed into all packages. However, if you need to have separate copyright
files for different binary packages, you can use files named
debian/package.copyright.
Any filenames specified as parameters will be installed into the first
package dh_installdocs is told to act on. By default, this is the first
binary package in debian/control, but if you use B<-p>, B<-i>, or B<-a> flags, it
will be the first package specified by those flags.
Also, debian/README.Debian (or debian/README.debian) and debian/TODO, if
they exist, will be installed into the first binary package listed in
debian/control, if dh_installdocs is acting on that package. Note that
debian/TODO will be installed named TODO.Debian, if the package is not a
debian native package. Also note that README.debian is installed as
README.Debian, for consistency. Note that debian/package.README.Debian and
debian/package.TODO can be used to specify files for subpackages.
Files named debian/package.docs can list other files to be installed.
Files named debian/package.doc-base, will be installed as doc-base control
files, and will make this program automatically generate the postinst and
prerm commands needed to interface with the doc-base package. Note that the
doc-id will be determined from the "Document:" entry in the
doc-base control file in question.
If your package needs to register more than one document, you need multiple
files. To accomplish this, you can use files named debian/package.doc-base.*
=head1 OPTIONS
=over 4
=item B<-A>, B<--all>
Install all files specified by command line parameters in ALL packages
acted on.
=item B<-n>, B<--noscripts>
Do not modify postinst/prerm scripts.
=item B<-Xitem>, B<--exclude=item>
Exclude files that contain "item" anywhere in their filename from
being installed. Note that this includes doc-base files.
=item I<file ...>
Install these files as documentation into the first package acted on. (Or
in all packages if B<-A> is specified).
=back
=head1 EXAMPLES
This is an example of a debian/package.docs file:
README
TODO
debian/notes-for-maintainers.txt
docs/manual.txt
docs/manual.pdf
docs/manual-html/
=head1 NOTES
Note that dh_installdocs will happily copy entire directory hierarchies if
you ask it to (similar to cp -a). If it is asked to install a
directory, it will install the complete contents of the directory.
Note that this command is not idempotent. L<dh_prep(1)> should be called
between invocations of this command. Otherwise, it may cause multiple
instances of the same text to be added to maintainer scripts.
