verified gcc-4.6.4.tar.bz2.sig;
imported gcc-4.6.4 source tree from verified upstream tarball.

downloading a git-generated archive based on the 'upstream' tag
should provide you with a source tree that is binary identical
to the one extracted from the above tarball.

if you have obtained the source via the command 'git clone',
however, do note that line-endings of files in your working
directory might differ from line-endings of the respective
files in the upstream repository.

+/**
+ * Beans implement this to get information about the execution environment and
+ * its services and to be placed in the hierarchy.
+ * <P>
+ *
+ * The difference between a <code>BeanContext</code> and a
+ * <code>BeanContextChild</code>, mainly, is that a
+ * <code>BeanContext</code> may be a parent.
+ * <P>
+ *
+ * <code>BeanContextChild</code> instances will be serialized at some
+ * point in their life, but you need to make sure your bean context does
+ * not contain a serializable reference (directly or indirectly) to the
+ * parent <code>BeanContext</code>, to any of the other
+ * <code>BeanContext</code>s in the tree, or to any resources obtained
+ * via the <code>BeanContextServices</code> interface.  One way to do this
+ * is to mark any fields that contain such references as
+ * <code>transient</code>.  Another way is to use a custom serializer.
+ * <P>
+ *
+ * If you do not do this, when the <code>BeanContext</code> is serialized,
+ * all the other <code>BeanContext</code>s and other unnecessary things
+ * will be serialized along with it.
+ * <P>
+ *
+ * Before dying, a <code>BeanContextChild</code> should call
+ * <code>getBeanContext().remove(this)</code> to detach from the
+ * hierarchy and exit cleanly.
