Usage: build-locale-archive [OPTION]... [TEMPLATE-FILE] [ARCHIVE-FILE]\n\
|
||||
Builds a locale archive from a template file.\n\
|
||||
Options:\n\
|
||||
-h, --help Print this usage message.\n\
|
||||
-v, --verbose Verbose execution.\n\
|
||||
-l, --install-langs=LIST Only include locales given in LIST into the \n\
|
||||
locale archive. LIST is a colon separated list\n\
|
||||
of locale prefixes, for example \"de:en:ja\".\n\
|
||||
The special argument \"all\" means to install\n\
|
||||
all languages and it must be present by itself.\n\
|
||||
If \"all\" is present with any other language it\n\
|
||||
will be treated as the name of a locale.\n\
|
||||
If the --install-langs option is missing, all\n\
|
||||
locales are installed. The colon separated list\n\
|
||||
can contain any strings matching the beginning of\n\
|
||||
locale names.\n\
|
||||
If a string does not contain a \"_\", it is added.\n\
|
||||
Examples:\n\
|
||||
--install-langs=\"en\"\n\
|
||||
installs en_US, en_US.iso88591,\n\
|
||||
en_US.iso885915, en_US.utf8,\n\
|
||||
en_GB ...\n\
|
||||
--install-langs=\"en_US.utf8\"\n\
|
||||
installs only en_US.utf8.\n\
|
||||
--install-langs=\"ko\"\n\
|
||||
installs ko_KR, ko_KR.euckr,\n\
|
||||
ko_KR.utf8 but *not* kok_IN\n\
|
||||
because \"ko\" does not contain\n\
|
||||
\"_\" and it is silently added\n\
|
||||
--install-langs\"ko:kok\"\n\
|
||||
installs ko_KR, ko_KR.euckr,\n\
|
||||
ko_KR.utf8, kok_IN, and\n\
|
||||
kok_IN.utf8.\n\
|
||||
--install-langs=\"POSIX\" will\n\
|
||||
installs *no* locales at all\n\
|
||||
because POSIX matches none of\n\
|
||||
the locales. Actually, any string\n\
|
||||
matching nothing will do that.\n\
|
||||
POSIX and C will always be\n\
|
||||
available because they are\n\
|
||||
builtin.\n\
|
||||
Aliases are installed as well,\n\
|
||||
i.e. --install-langs=\"de\"\n\
|
||||
will install not only every locale starting with\n\
|
||||
\"de\" but also the aliases \"deutsch\"\n\
|
||||
and and \"german\" although the latter does not\n\
|
||||
start with \"de\".\n\
|
||||
\n\
|
||||
If the arguments TEMPLATE-FILE and ARCHIVE-FILE are not given the locations\n\
|
||||
where the glibc used expects these files are used by default.\n\
