=head1 NAME

B<installdeb-ispell> - debhelper-like utility for
maintainers of ispell dictionary Debian packages

=head1 SYNOPSIS

 installdeb-ispell [debhelper options] [options]

=head1 DESCRIPTION

B<installdeb-ispell> is a debhelper like program that is
responsible for installing appropriate debconf config and templates
files and debhelper snippets in
an ispell dictionary package,
according to the Debian Spell Dictionaries and Tools Policy.

For more details, see
 /usr/share/doc/dictionaries-common-dev/dsdt-policy.txt.gz

The actions executed by B<installdeb-ispell> are the
following:

=over

=item * Maintainer Scripts

B<installdeb-ispell> installs the necessary
scraps of code in the F<postinst> and F<postrm> scripts.

=item * Language info file

B<installdeb-ispell> also checks a file containing
ispell dictionary information, called
F<debian/info-ispell> or
F<debian/package.info-ispell>.  If this file is
successfully parsed, it is installed in the
F</var/lib/dictionaries-common/ispell> directory.

=item * Substvars substitutions

This script will populate a F<substvars> file, so Depends line in
control file can contain
${ispell:Depends} to
automatically care for dictionaries-common dependencies.

This requires C<Build-Depends> on at least dictionaries-common-dev
1.23.0 and is highly recommended.

=item * Debconf files

=over

=item o templates and config files

B<installdeb-ispell> installs the Policy compliant
Debconf files from the information contained in the
F<info-ispell> file.  These files are created as
F<debian/config> (or F<debian/package.config>) and F<debian/templates>
(or F<debian/package.templates>).  No intervention is needed here,
since B<installdeb-ispell> will make a call to
dh_installdebconf(1).

If the package needs to have special code in the F<config> file, the maintainer
should supply files called F<debian/config.in> (or
F<debian/package.config.in>). In the F<config.in> file, the string
C<#DEBHELPER#> must appear alone in one line and start at the first
column.  B<installdeb-ispell> will replace that
token with the necessary Policy compliant code (this works with
F<config.in> is either a Bourne shell or Perl script).

If the package needs to define its own questions via the F<templates>
file the maintainer should either supply files F<debian/po-master.templates>
(or F<debian/package.po-master.templates>) together with the appropriate
po files if the package handles template localization through po-debconf,
or F<debian/templates.in> (or F<debian/package.templates.in>) otherwise.
See the po-debconf(7) manual page for more details and remember that the
master templates name is now different.

The templates defined in the F<templates.in> or F<po-master.templates> files
are merged into the Policy compliant templates by
installdeb-ispell and a call to dh_installdebconf(1)
is internally done.

=item o The elanguages template field

This field is useful if you want to override the debconf languages string
with something different (since the master string remains the same, this
will not trigger a new debconf call) or if you really think that the
languages string should be internationalized for your package. Note that
for most packages the poor man default localization should be enough, and
translators should have another priorities.

installdeb-ispell default behavior is not adding an
C<elanguages> field to the templates file. If you want it added you have
to call the script with the explicit B<--write-elanguages> option.

This field will be added with value taken from the C<Elanguage> entry in
the info file if present, or after the C<Language> value otherwise. Note
that this is useful only if:

=over

=item - You want to fix a buggy entry

In this case just fill the C<Elanguage> field in the info file with the
new value. This will be shown at the debconf prompt.

=item - You want to fully internationalize your entries

In this case some black magic is needed at first time for smooth use,

=over

=item (a) Run B<installdeb-{ispell,wordlist} --no-installdebconf --write-elanguages> for
      every package whose string should be internationalized. Edit the
      created F<.templates> files and remove the leading underscores in
      the elanguages entry if present.

=item (b) Run B<debconf-gettextize templates_to_be_internationalized>.
      Check that all the desired F<.templates> files are in
      F<debian/po/POTFILES.in> and remove old F<.config> and
      F<.templates> files.

=item (c) Run again B<installdeb-{ispell,wordlist} --no-installdebconf --write-elanguages> and
      B<debconf-updatepo> (no edit here) to remove references to
      non-translatable strings. Check that the desired strings are in the po
      master file (F<debian/po/templates.pot>) and remove F<.config> and
      F<.templates> files. You are done. If the master C<Elanguages> string
      is changed, repeat (c) afterward.

=item * Extra installdeb-ispell options in Language info file

For benefit of ispell dictionaries using B<ispell-autobuildhash>,
B<installdeb-ispell> script will look for C<'auto-compat'> fields in
F<$dict.info-ispell>, containing base name(s) of your compat file(s).
If C<'auto-compat'> entry is found two debhelper snippets are added,
one to create/reset compatfile(s) in postinst and the other to remove
files in a removal list from postrm.
Removal list will contain compat file(s) and associated hash(es) with
the same basename.

F</usr/lib/ispell/$dict.hash -E<gt> /var/lib/ispell/$dict.hash>
symlinks are no longer created automatically by this script.
They are now created by new ispell-autobuildhash together with the
relevant hashes.
Make sure to depend on at least dictionaries-common 1.23
(See F<dictionaries-common.checklist>). 

=back

=head1 OPTIONS

The usual dephelper(1) options are accepted. Options below are specific
to B<installdeb-ispell>

=over

=item B<--no-installdebconf>

Do not run B<dh_installdebconf> nor remove templates and config file.

=item B<--no-pre-post>

Do not install {pre,post}{inst,rm} snippets.

=item B<--write-elanguages>

Create the elanguages stuff.

=item B<--debug>

Show some extra info.

=head1 NOTES

This program is not part of debhelper, although it is intended to be used
in ispell dictionary packages using debhelper in its
building.
