From f34478cbe0214a201e7ecef3e79ed6c957b7beee Mon Sep 17 00:00:00 2001 From: Lars Hjemli Date: Mon, 24 Mar 2008 16:00:27 +0100 Subject: Refactor snapshot support The snapshot support needs to be split between output- and config-related functions to get the layering between shared.c and ui-*.c right. There is also some codestyle-issues which needs fixing to make the snapshot functions more similar to the rest of the cgit code.
