+ 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\
