From 84c3fb07b0b8199c7f85c5de280e7100bad0786f Mon Sep 17 00:00:00 2001 From: Jaromil Date: Sat, 23 Apr 2011 11:49:47 +0200 Subject: directory re-organization (keeps the old build system) there is no internal modification of any file in this commit files are moved into directories according to established standards in sourcecode distribution; these directories contain: src - Files that are used in constructing the executable binaries, but are not installed. doc - Files in HTML and text format that document usage, quirks of the implementation, and contributor checklists. locale - Files that contain human language translation of strings used in the program contrib - Files contributed from distributions or other third party implementing scripts and auxiliary programs --- irc.cpp | 445 ---------------------------------------------------------------- 1 file changed, 445 deletions(-) delete mode 100644 irc.cpp (limited to 'irc.cpp') diff --git a/irc.cpp b/irc.cpp deleted file mode 100644 index 5adaf11658..0000000000 --- a/irc.cpp +++ /dev/null @@ -1,445 +0,0 @@ -// Copyright (c) 2009-2010 Satoshi Nakamoto -// Distributed under the MIT/X11 software license, see the accompanying -// file license.txt or http://www.opensource.org/licenses/mit-license.php. - -#include "headers.h" - -int nGotIRCAddresses = 0;
