From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001
From: upstream source tree <ports@midipix.org>
Date: Sun, 15 Mar 2015 20:14:05 -0400
Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; 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.

+ * The implementation of a generic {@link java.security.KeyPairGenerator}

+ * <p>
+ * This class defines the <i>Service Provider Interface</i> (<b>SPI</b>) for
+ * the {@link java.security.KeyPairGenerator} class, which is used to generate
+ * pairs of public and private keys.
+ * <p>
+ * All the abstract methods in the {@link java.security.KeyPairGeneratorSpi}
+ * class are implemented by this class and all its sub-classes.
+ * <p>
+ * In case the client does not explicitly initialize the KeyPairGenerator (via a
+ * call to an <code>initialize()</code> method), the GNU provider supplies
+ * (and document) default values to be used. For example, the GNU provider uses
+ * a default <i>modulus</i> size (keysize) of 1024 bits for the DSS (Digital
+ * Signature Standard) a.k.a <i>DSA</i>.
