| " This Vim script is used for detecting if a translation of the |
| " tutor file exist, i.e., a tutor.xx file, where xx is the language. |
| " If the translation does not exist, or no extension is given, |
| " it defaults to the English version. |
| |
| " It is invoked by the vimtutor shell script. |
| |
| " 1. Build the extension of the file, if any: |
| let s:ext = "" |
| if strlen($xx) > 1 |
| let s:ext = "." .. $xx |
| else |
| let s:lang = "" |
| " Check that a potential value has at least two letters. |
| " Ignore "1043" and "C". |
| if exists("v:lang") && v:lang =~ '\a\a' |

| elseif $LC_ALL =~ '\a\a' |

| " LC_MESSAGES=C can be used to explicitly ask for English messages while |
| " keeping LANG non-English; don't set s:lang then. |

| " about other languages? |
