36 * Revision 1.4 2001/05/20 16:44:47 jongfoster
37 * Removing last hardcoded JunkBusters.com URLs.
39 * Revision 1.3 2001/05/20 01:21:20 jongfoster
40 * Version 2.9.4 checkin.
41 * - Merged popupfile and cookiefile, and added control over PCRS
42 * filtering, in new "permissionsfile".
43 * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
44 * file error you now get a message box (in the Win32 GUI) rather
45 * than the program exiting with no explanation.
46 * - Made killpopup use the PCRS MIME-type checking and HTTP-header
48 * - Removed tabs from "config"
49 * - Moved duplicated url parsing code in "loaders.c" to a new funcition.
50 * - Bumped up version number.
52 * Revision 1.2 2001/05/17 23:01:01 oes
53 * - Cleaned CRLF's from the sources and related files
55 * Revision 1.1.1.1 2001/05/15 13:59:03 oes
56 * Initial import of version 2.9.3 source tree
