    <title>Introduction to GC</title>

    <para>The <application>GC</application> package contains the
    Boehm-Demers-Weiser conservative garbage collector, which can be used as a
    garbage collecting replacement for the C malloc function or C++ new
    operator. It allows you to allocate memory basically as you normally would,
    without explicitly deallocating memory that is no longer useful. The
    collector automatically recycles memory when it determines that it can no
    longer be otherwise accessed. The collector is also used by a number of
    programming language implementations that either use C as intermediate
    code, want to facilitate easier interoperation with C libraries, or just
    prefer the simple collector interface. Alternatively, the garbage collector
    may be used as a leak detector for C or C++ programs, though that is not
    its primary goal.</para>
