## NAME
       aspell-autobuildhash - Autobuilding aspell hash files for some dicts

## SYNOPSIS
        aspell-autobuildhash [--force]

          Options:
           --debug      Show extra info about aspell-autobuildhash internal
                        work. Will also enable aspell affix validation.
           --dry-run    Show what would be done, but do nothing real.
           --force      Rebuild the hash file for all dicts providing a
                        compat file skipping the test.
           --triggered  Tell the script that is run in the triggers stage.

## DESCRIPTION
       **aspell-autobuildhash** is a script that will manage aspell hash files autobuild, intended to be
       called from the dictionaries-common tools.  Depending on the aspell compatibility level and
       on the compatibility level used for the hash file if present, will decide whether it must be
       rebuilt or not. This script will only work on aspell packages prepared to use it, it will do
       nothing for other aspell dict packages.

## OPTIONS
        --debug      Show some extra information about aspell-autobuildhash
                     internal work. Will also enable aspell affix validation.
        --dry-run    Show what would be done, but do nothing real.
        --force      Rebuild the hash file for all dicts providing a compat
                     file regardless of the compatibility levels found.
        --triggered  Tell the script that is run in the triggers stage. When
                     run under dpkg control, do not try to set the
                     'aspell-autobuildhash' trigger, but run real
                     B<aspell-autobuildhash> code. When not run under dpkg
                     control, real code will always be run and '--triggered'
                     option has no real effect.

## PACKAGE MAINTAINERS
       To use this system, **aspell-autobuildhash** expects a _$lang.compat_ file in _/var/lib/aspell_
       (_$lang_ stands for the lang basename with variant if any, e.g. _$lang_ is something like _gl-_
       _minimos_ or _en_)) containing aspell compatibility version for last successful build or "0" or
       en empty file if hash is to be rebuild, as is for dictionary installation and upgrades.

       When upgrading **aspell**, script will check if version in _$lang.compat_ is different from
       _aspell.compat_ and rebuild if so, updating _$lang.compat_ with the new value.

       Wordlists should previously be compressed either with gzip (and their extensions set as
       _.mwl.gz_ or _.wl.gz_) or preferably first with aspell prezip and then gzipped (with _.cwl.gz_
       extension).  This applies both for plain wordlists and munched wordlists (in the ispell way)
       if you use affix compression.

       If your package will provide a single hash, install prezipped+gzipped wordlist as
       _/usr/share/aspell/$lang.cwl.gz_ or, if prezip is not used, as _/usr/share/aspell/$lang.mwl.gz_.

       If your package will provide more than one aspell hash for the same $lang, you will need to
       place each compressed wordlist as e.g.  _/usr/share/aspell/$subdict.cwl.gz_, and the common
       _$lang.compat_ as above. Then create a _/usr/share/aspell/$lang.contents_ file with the base
       names of the subdicts, one in a line. For English that will contain, amongst other possible
       lines

        en-common
        en-variant_0
        en-variant_1
        en-variant_2
        en_CA-w_accents-only

       No need to use this file if a single hash is being created.

       Dictionaries-common scripts will call internally this script and create a single hash file at
       _/var/lib/ispell/$lang.rws_, or hash files at _/var/lib/ispell/$subdict.rws_. You must set a
       symlink to that files from _/usr/lib/aspell/$lang.rws_ or _/usr/lib/aspell/$subdict.rws_ as
       appropriate.

       Aspell dictionary packages using this script must make sure that _$lang.compat_ is reset on
       every new install/upgrade, so hash is rebuilt.  They must also make sure that _$lang.compat_
       and all of _/var/lib/aspell/$lang.rws_ or _/var/lib/aspell/$subdict.rws_ are removed on package
       removal.

       As of version 1.10, **installdeb-aspell** script will understand 'auto-compat' and
       'auto-contents' fields in _$dict.info-aspell_ file to help with this by adding needed debhelper
       snippets.  Put in that entry the base name(s) of your compat and contents file(s) and
       carefully check resulting maintainer scripts after build.

       Note that you are no longer suggested to ship empty files at any of
       _/var/lib/aspell/$lang.compat_, _/var/lib/aspell/$lang.rws_ or _/var/lib/aspell/$subdict.rws_, but
       explicitly create/update them on install and explicitly remove them on removal.

       **aspell** maintainer should also call this script from package postinst.  When comparing
       versions it will get the aspell version from file _/usr/share/aspell/aspell.compat_.
