dh_installdocs - install documentation into package build directories
<A NAME="lbAC">&nbsp;</A>
<H2>SYNOPSIS</H2>
<B>dh_installdocs</B> [<I>debhelper options</I>] [<B>-A</B>] [<B>-X</B><I>item</I>] [<I>file</I> ...]
<A NAME="lbAD">&nbsp;</A>
<H2>DESCRIPTION</H2>
<B>dh_installdocs</B> is a debhelper program that is responsible for installing
documentation into <I>usr/share/doc/package</I> in package build directories.
<P>
In compat 10 and earlier, <B><A HREF="/cgi-bin/man/man2html?1+dh_install">dh_install</A></B>(1) may be a better tool for handling
the upstream documentation, when upstream's own build system installs all the desired documentation
correctly. In this case, <B>dh_installdocs</B> is still useful for installing
packaging related documentation (e.g. the <I>debian/copyright</I> file).
<P>
From debhelper compatibility level 11 on, <B>dh_install</B> will fall back to
looking in <I>debian/tmp</I> for files, if it does not find them in the current
directory (or wherever you've told it to look using <B>--sourcedir</B>).
<P>
In compat 11 and later, <B>dh_installdocs</B> offers many of the features that
<B><A HREF="/cgi-bin/man/man2html?1+dh_install">dh_install</A></B>(1) also has. Furthermore, <B>dh_installdocs</B> also supports
the <B>nodoc</B> build profile to exclude documentation (regardless of compat
level).
<A NAME="lbAE">&nbsp;</A>
<H2>FILES</H2>
<DL COMPACT>
<DT id="1">debian/<I>package</I>.docs<DD>
List documentation files to be installed into <I>package</I>.
<P>
Supports substitution variables in compat 13 and later as
documented in <B><A HREF="/cgi-bin/man/man2html?7+debhelper">debhelper</A></B>(7).
<DT id="2"><I>debian/copyright</I><DD>
The copyright file is installed into all packages, unless a more
specific copyright file is available.
<DT id="3">debian/<I>package</I>.copyright<DD>
<DT id="4">debian/<I>package</I>.README.Debian<DD>
<DT id="5">debian/<I>package</I>.TODO<DD>
Each of these files is automatically installed if present for a
<I>package</I>.
<DT id="6"><I>debian/README.Debian</I><DD>
<DT id="7"><I>debian/TODO</I><DD>
These files are installed into the first binary package listed in
debian/control.
<P>
Note that <I></I><FONT SIZE="-1"><I>README</I></FONT><I>.debian</I> files are also installed as <I></I><FONT SIZE="-1"><I>README</I></FONT><I>.Debian</I>,
and <I></I><FONT SIZE="-1"><I>TODO</I></FONT><I></I> files will be installed as <I></I><FONT SIZE="-1"><I>TODO</I></FONT><I>.Debian</I> in non-native packages.
<DT id="8">debian/<I>package</I>.doc-base<DD>
Installed as doc-base control files. Note that the doc-id will be
determined from the <B>Document:</B> entry in the doc-base control file in
question. In the event that multiple doc-base files in a single source
package share the same doc-id, they will be installed to
usr/share/doc-base/package instead of usr/share/doc-base/doc-id.
<DT id="9">debian/<I>package</I>.doc-base.*<DD>
If your package needs to register more than one document, you need
multiple doc-base files, and can name them like this. In the event
that multiple doc-base files of this style in a single source package
share the same doc-id, they will be installed to
usr/share/doc-base/package-* instead of usr/share/doc-base/doc-id.
</DL>
<A NAME="lbAF">&nbsp;</A>
<H2>OPTIONS</H2>
<DL COMPACT>
<DT id="10"><B>-A</B>, <B>--all</B><DD>
Install all files specified by command line parameters in <FONT SIZE="-1">ALL</FONT> packages
acted on.
<DT id="11"><B>-X</B><I>item</I>, <B>--exclude=</B><I>item</I><DD>
Exclude files that contain <I>item</I> anywhere in their filename from
being installed. Note that this includes doc-base files.
<DT id="12"><B>--sourcedir=</B><I>dir</I><DD>
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).
<P>
Note that this is not the same as the <B>--sourcedirectory</B> option used
by the <B>dh_auto_</B><I>*</I> commands. You rarely need to use this option, since
<B>dh_installman</B> automatically looks for files in <I>debian/tmp</I> in debhelper
compatibility level 11 and above.
<DT id="13"><B>--doc-main-package=</B><I>main-package</I><DD>
Set the main package for a documentation package. This is used to
install the documentation of the documentation package in <I>/usr/share/doc/main-package</I> as recommended by the Debian policy
manual 3.9.7 in §12.3.
<P>
In compat 11 (or later), this option is only useful if debhelper's
auto-detection of the main package is wrong. The option can also be
used to silence a warning from debhelper when the auto-detection fails
but the default happens to be correct.
<P>
This option cannot be used when <B>dh_installdocs</B> is instructed to act
on multiple packages. If you need this option, you will generally
need to combine it with <B>-p</B> to ensure exactly one package is acted
on.
<P>
Please keep in mind that some documentation (the copyright file,
<FONT SIZE="-1">README</FONT>.Debian, etc.) will be unaffected by this option.
<DT id="14"><B>--link-doc=</B><I>package</I><DD>
Make the documentation directory of all packages acted on be a symlink to
the documentation directory of <I>package</I>. This has no effect when acting on
<I>package</I> itself, or if the documentation directory to be created already
exists when <B>dh_installdocs</B> is run. To comply with policy, <I>package</I> must
be a binary package that comes from the same source package.
<P>
debhelper will try to avoid installing files into linked documentation
directories that would cause conflicts with the linked package. The <B>-A</B>
option will have no effect on packages with linked documentation
directories, and <I>copyright</I>, <I>changelog</I>, <I></I><FONT SIZE="-1"><I>README</I></FONT><I>.Debian</I>, and <I></I><FONT SIZE="-1"><I>TODO</I></FONT><I></I> files will
not be installed.
<P>
(An older method to accomplish the same thing, which is still supported,
is to make the documentation directory of a package be a dangling symlink,
before calling <B>dh_installdocs</B>.)
<P>
Please note that this option only applies to the documentation
directory for the package itself. When the package ships
documentation for another package (e.g. see <B>--doc-main-package</B>), it
will not use a symlink for the documentation of the other package.
<P>
<B></B><FONT SIZE="-1"><B>CAVEAT 1</B></FONT><B></B>: If a previous version of the package was built without this
option and is now built with it (or vice-versa), it requires a ``dir to
symlink'' (or ``symlink to dir'') migration. Since debhelper has no
knowledge of previous versions, you have to enable this migration
itself.
<P>
This can be done by providing a &quot;debian/<I>package</I>.maintscript&quot; file
and using <B><A HREF="/cgi-bin/man/man2html?1+dh_installdeb">dh_installdeb</A></B>(1) to provide the relevant maintainer
script snippets.
<P>
<B></B><FONT SIZE="-1"><B>CAVEAT 2</B></FONT><B></B>: The use of <B>--link-doc</B> should only be done when the
packages have same ``architecture'' type. A link from an architecture
independent package to an architecture dependent package (or vice
versa) will not work. Since compat 10, debhelper will actively reject
unsupported combinations.
<DT id="15"><I>file</I> ...<DD>
Install these files as documentation into the first package acted on. (Or
in all packages if <B>-A</B> is specified).

<H2>NOTES</H2>
Note that <B>dh_installdocs</B> will happily copy entire directory hierarchies if
you ask it to (similar to <B>cp -a</B>). If it is asked to install a
directory, it will install the complete contents of the directory.
