Language pack sizes =================== langpack-o-matic has a script 'langpacksize' that helps to determine which packages fit on the CDs. You can download the latest version from http://bazaar.launchpad.net/~ubuntu-langpack/langpack-o-matic/main/view/head:/langpacksize This script prints a table of languages vs. categories and their single and cumulative sizes; by default, the numbers are bytes, but when being invoked with 'MB' as first argument, the numbers will be MB. E. g.: en G: 5.30 K: 5.55 G+K: 7.93 GSum: 5.30 KSum: 5.55 G+KSum: 7.93 es G: 3.57 K: 4.76 G+K: 6.16 GSum: 8.87 KSum: 10.32 G+KSum: 14.09 'G' is the size of base+gnome (as needed for Ubuntu CDs), 'K' is the size of base+kde (Kubuntu), 'G+K' is the size of base+gnome+kde (Edubuntu). In this context, 'base' means packages which are UI independent, such as coreutils, gcc, or hwdb-client. The 'Sum' field show the cumulative size of the packages for that language and all languages above it. The list is vertically ordered by the priority, i. e. they should be added from top to down. Input support packages ====================== When shipping a language on a CD, the required input support packages should be shipped as well. To find out the necessary packages, run this command for the particular language code: check-language-support -l ja --show-installed -p ibus This displays the input methods for Japanese ("ja").
