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 textproto package implements generic support for
+// text-based request/response protocols in the style of
+// HTTP, NNTP, and SMTP.
+//
+// The package provides:
+//
+// Error, which represents a numeric error response from
+// a server.
+//
+// Pipeline, to manage pipelined requests and responses
+// in a client.
+//
+// Reader, to read numeric response code lines,
+// key: value headers, lines wrapped with leading spaces
+// on continuation lines, and whole text blocks ending
+// with a dot on a line by itself.
+//
+// Writer, to write dot-encoded text blocks.
