+=head1 NAME
+
+config/auto/boehm.pm - Test for Boehm GC availability.
+
+=head1 DESCRIPTION
+
+Determines whether the platform supports Boehm GC.
+
+From L<http://www.hpl.hp.com/personal/Hans_Boehm/gc/>: "The Boehm-Demers-Weiser
+conservative garbage collector can be used as a garbage collecting replacement
+for C malloc or C++ new. 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."
