I had to use I18N::LangTags::Detect last night and when I saw in the doco that it looks for "several environment variables, including [list of variables]" I thought "OK, so what other variables are involved that I'll need to control from my tests?" and had to read the source. One of the patches attached to this message updates the doco to make it clear exactly which variables it looks at. While reading the source I also found an undocumented environment variable, so there's a little patch for that too. -- David CantrellThread Next
