    \title FileTagger Item
    \brief Maps file patterns to tags.

    This item maps file patterns to tags. It can be attached to a product or a module.
    In the latter case, its effect is the same as if it had been attached to all products having
    a dependency on the respective module. For instance, the cpp module of \QBS has, among others,
    the following file tagger:
    \code
    FileTagger {
        patterns: "*.cpp"
        fileTags: ["cpp"]
    }
    \endcode

    As a result, the "cpp" tag is automatically attached to all files ending with ".cpp" in
    products depending on the cpp module. This causes them to be compiled, because a C++
    compiler rule has "cpp" in its list of matching input tags.

    File taggers are disabled if file tags are set explicitly in a product or group.
    For example, the "cpp" tag is not attached to the cpp files in the following product:

    \code
    Product {
        Depends { name: "cpp" }
        Group {
            files: "*.cpp"
            fileTags: "other"
        }
    }
    \endcode
