=head1 Data structures & functions

=head2 Languages

=over

=item our %lang

The key is the  lang name (locale name for some (~5) special cases needing
extra distinctions)

The fields are:

=over 4

=item 0 lang name in English

=item 1 transliterated locale name in the locale name (used for sorting)

=item 2 default locale name to use for that language if there is not
an existing locale for the combination language+country chosen

=item 3 geographic groups that this language belongs to (for displaying
in the menu grouped in smaller lists):

=over 4

=item 1=Europe,

=item 2=Asia,

=item 3=Africa,

=item 4=Oceania & Pacific,

=item 5=America

=back

If you wonder, it's the order used in the Olympic flag...

=item 4 special value for LANGUAGE variable (if different of the default
of 'll_CC:ll_DD:ll' (ll_CC: locale (if exist) resulting of the
combination of chosen lang (ll) and country (CC), ll_DD: the
default locale shown here (field [2]) and ll: the language (the key))

The key is the ISO 639-1 country name code (that should be YY in xx_YY locale).

The fields are:

=over 4

=item 0: country name in natural language

=item 1: default locale for that country

=item 2: geographic groups that this country belongs to (for displaying
in the menu grouped in smaller lists):

=over 4

=item *1=Europe,

=item *2=Asia,

=item *3=Africa,

=item 4=Oceania & Pacific,

=item 5=America

If you wonder, it's the order used in the Olympic flag.

Note: for countries for which a glibc locale do not exist (yet) I tried to
put a locale that makes sense; and a '#' at the end of the line to show
the locale is not the "correct" one. 'en_US' is used when no good choice
is available.

Example:

   C<< 'FR' => [ N_("France"), 'fr_FR', '1' ], >>

=head2 Input Methods (IM)

Various hash tables enables to configure IMs.

=over

=item my @IM_i18n_fields;

This set generic IM fields:

=over 4

=item * B<XMODIFIERS>: is the environnement variable used by the X11 XIM protocol
it is of the form XIMODIFIERS="@im=foo"

=item * B<XIM>: is used by some programs, it usually is the like XIMODIFIERS
with the "@im=" part stripped

=item * B<GTK_IM_MODULE>: the module to use for Gtk programs ("xim" to use an X11
XIM server; or a a native gtk module if exists)

=item * B<XIM_PROGRAM>: the XIM program to run (usually the same as XIM value, but
in some cases different, particularly if parameters are needed;

=item * B<QT_IM_MODULE>: the module to use for Qt programs ("xim" to use an X11
XIM server; or a Qt plugin if exists)

=back

=cut

my @IM_i18n_fields = qw(XMODIFIERS XIM GTK_IM_MODULE XIM_PROGRAM QT_IM_MODULE);

my ($is_kde4);

=item my %IM_config;

In order to configure an IM, one has to put generic configuration here.
Fields are :

=over 4

=item * B<GTK_IM_MODULE>: the Gtk+ IM module to use

=item * B<QT_IM_MODULE>: the Qt IM module to use

=item * B<XIM>: 

=item * B<XIM_PROGRAM>: the XIM program to use

=item * B<XMODIFIERS>: the X Modifiers (see X11 config), eg: C<'@im=gcin'>,

See above for those 5 parameters.

=item * B<default_for_lang>: the language codes for which it's the default IM
=item * B<langs>: 'zh',

=item * B<packages:> a hash ref that contains subroutine references:

=over 4

=item * B<generic>: packages that must be installed for all languages

=item * B<common>: packages that are shared between per language & generic packages

=item * eventually several B<code_lang> returning per language packages

=back

The I<packages> field must be kept in sync with meta-task's C<rpmsrate-raw>, especially for the per language package selection!

The actual packages list will consist of:

=over 4

=item * either per language package list or I<generic> list

=item * plus the packages returned by I<common>
