description="
A garbage collector for C and C++.

The gc 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.
