    23 23 
     The BuildElement class is a convenience element one can derive from for
    24 24 
     implementing the most common case of element.

    29 
    +The BuildElement base class provides built in functionality that could be overridden by the
    30 
    +individual plugins.
    31 
    +
    32 
    +This section will give a brief summary of how some of the common features work, some of them or the variables they
    33 
    +use will be further detailed in the following sections.
    34 
    +
    35 
    +* Location for running commands
    36 
    +
    37 
    + The ``command-subdir`` variable sets where the build commands will be executed, if the directory dose not exist it
    38 
    + will be created, it is defined relative to the buildroot.
    39 
    +
    40 
    +* Location for configuring the project
    41 
    +
    42 
    + The ``conf-root`` is defined by default as ``.`` and is the location that specific build element can use to look
    43 
    + for build configuration files, currently autotools and cmake use this.
    44 
    +
    45 
    + The configuration commands are run in ``command-subdir`` and by default ``conf-root`` is ``.`` so if
    46 
    + ``conf-root`` is not set the configuration files in ``command-subdir`` will be used.
    47 
    +
    48 
    + By setting ``conf-root`` to ``"%{build-root}/Source/conf_location"`` and your source elements ``directory`` variable
    49 
    + to ``Source`` then the configuration files in the directory ``conf_location`` with in your Source will be used.
    50 
    + However the location where your configuration command will be run will still be wherever you set your
    51 
    + ``command-subdir`` to be.
    52 
    +
    53 
    +* Install Location
    54 
    +
    55 
    +  You should not change the ``install-root`` variable as it is a special writeable location in the sandbox but it is
    56 
    +  useful when writing custom install instructions as it may need to be supplied as the ``DESTDIR``, please see the
    57 
    +  cmake build element for example.

    +
    29 
    +* Directory
    30 
    +
    31 
    +  The ``directory`` variable can be set for all sources of a type in project.conf
    32 
    +  or per source within a element.
    33 
    +
    34 
    +  This sets the location with in the build root that the content of the source will be
    35 
    +  loaded in to. If the location dose not exist it will be created.
