    \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 or JavaScript file.

    \section1 Available Operations

    \section2 qbs.getEnv
    \code
    qbs.getEnv(key: string): string
    \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 qbs.getHash
    \code
    qbs.getHash(key: string): string
    \endcode
    Calculates a 16-byte hash of the input and returns it.
    Rules in modules should use this function to find unique locations for output
    artifacts in the build directory without duplicating the whole directory structure of
    the respective input file (to deal with the case of two files with the same name in different
    subdirectories of the same product).

    \section2 qbs.rfc1034Identifier
    \code
    qbs.rfc1034Identifier(str: string): string
    \endcode
    Returns an RFC 1034 compliant identifier based on the given string by replacing each character
    that is not Latin alphanumeric or \c{.} with \c{-}.

    \section2 loadFile
    \code
    loadFile(filePath: string): any
    \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.
    For example:
    \code
    var MyFunctions = loadFile("myfunctions.js");
    MyFunctions.doSomething();
    \endcode

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


    \section1 Extensions to JavaScript Built-in Objects

    \section2 Array.contains
    \code
    Array.contains(e: any): boolean
    \endcode
    Returns \c{true} if the array contains the element \c{e}. Returns \c{false} otherwise.

    \section2 Array.uniqueConcat
    \code
    Array.uniqueConcat(other: any[]): any[]
    \endcode
    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 String.contains
    \code
    String.contains(s: string): boolean
    \endcode
    Returns \c{true} if the string contains the substring \c{s}. Returns \c{false} otherwise.

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

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