    \title General Services
    \brief Provides various operations.

    These are operations that do not fit into any of the other categories.
    They are automatically available in any \QBS project file.

    \section1 Available Operations

    \section2 getEnv
    \code
    qbs.getEnv(name)
    \endcode
    Tries to find a variable with the given name in the build environment and returns its value. If
    no such variable could be found, \c undefined is returned.

    \section2 getHostOS
    \code
    qbs.getHostOS(name)
    \endcode
    Returns the name of the operating system on which \QBS is running.
    \note Do not confuse this with the \c{qbs.targetOS} property, which represents the operating
    system on which the binaries produced by \QBS will run.

    \section2 loadFile
    \code
    var MyFunctions = loadFile("myfunctions.js");
    MyFunctions.doSomething();
    \endcode
    Loads a JavaScript file and returns an object that contains the evaluated context of this file.
    This function is only available in JavaScript files.

    \section2 loadExtension
    \code
    var FileInfo = loadExtension("qbs.FileInfo");
    var fileName = FileInfo.fileName(filePath);
    \endcode
    Loads a \QBS extension and returns an object that contains all functions of that extension.
    This function is only available in JavaScript files.


    \section1 Extensions to JavaScript Built-in Objects

    \section2 \c{Array.contains(e)}
    Returns \c{true} if the array contains the element \c{e}. Returns \c{false} otherwise.

    \section2 \c{Array.uniqueConcat(other)}
    Returns a copy of this array joined with the array \c{other}.
    Duplicates that would originate from the concatenation are removed.
    The order of elements is preserved.

    \section2 \c{String.contains(s)}
    Returns \c{true} if the string contains the substring \c{s}. Returns \c{false} otherwise.

    \section2 \c{String.startsWith(s)}
    Returns \c{true} if the string starts with the substring \c{s}. Returns \c{false} otherwise.

    \section2 \c{String.endsWith(s)}
    Returns \c{true} if the string ends with the substring \c{s}. Returns \c{false} otherwise.
