From f431cd1a48a6a5186633bf5f16a2d21cb4399e8c Mon Sep 17 00:00:00 2001 From: P. J. McDermott Date: Thu, 09 Feb 2012 10:56:43 -0500 Subject: Initial commit. TODO: Copyright information. Including source code and a patch to add files generated by GNU Autoconf is not very pretty... Running 'make dist' in the SVN trunk to generate a source archive might be better. --- (limited to 'src/libopkg/.svn/text-base/pkg_vec.c.svn-base') diff --git a/src/libopkg/.svn/text-base/pkg_vec.c.svn-base b/src/libopkg/.svn/text-base/pkg_vec.c.svn-base new file mode 100644 index 0000000..472962c --- /dev/null +++ b/src/libopkg/.svn/text-base/pkg_vec.c.svn-base @@ -0,0 +1,208 @@ +/* pkg_vec.c - the opkg package management system + + Steven M.
