18 dh_installdebconf is a debhelper program that is responsible for installing
19 files used by the debconf package into package build directories.
21 It also automatically generates the postrm commands needed to
22 interface with debconf. See L<dh_installdeb(1)> for an explanation of how
25 Files named debian/package.config and debian/package.templates are
26 installed into the DEBIAN directory in the package build directory.
27 If a file named debian/package.config.debhelper exists, the contents
28 of that file are merged into the config script as follows: If the script
29 exists, then anywhere in it that "#DEBHELPER#" appears, the text of the
30 .debhelper file is inserted. If the script does not exist, then a script
31 is generated from the .debhelper file. The .debhelper files may be created
32 by other debhelper programs, and are shell script fragments.
34 Note that if you use debconf, your package probably needs to depend on it
35 (it will be added to ${misc:Depends} by this program).
37 Note that for your config script to be called by dpkg, your postinst
38 needs to source debconf's confmodule. dh_installdebconf does not
39 install this statement into postinst automatically as it it too hard to
42 =head1 LOCALIZED TEMPLATE FILES
44 Debconf also supports localized template files, and this program has some
45 support to aid is working with them. It is best to keep the translations in
46 .po files under debian/po, and merge them only at build time. See
47 L<po2debconf(1)> and L<debconf-getlang(1)> for details.
49 This program will look to see if you have a debian/po directory and if so will
50 automatically call L<po2debconf(1)> to generate a merged templates file. Or
51 if you have debian/templates.ll files, it will use the older
52 L<debconf-mergetemplate(1)> program to merge those together.
54 Note that if your package has a debian/po directory it should build-depend on po-debconf.
56 For example, if you have a German translation,
57 strings from debian/po/de.po are merged with debian/package.templates.
