* Revisions :
* $Log: loaders.c,v $
+ * Revision 1.7 2001/05/26 00:28:36 jongfoster
+ * Automatic reloading of config file.
+ * Removed obsolete SIGHUP support (Unix) and Reload menu option (Win32).
+ * Most of the global variables have been moved to a new
+ * struct configuration_spec, accessed through csp->config->globalname
+ * Most of the globals remaining are used by the Win32 GUI.
+ *
+ * Revision 1.6 2001/05/23 12:27:33 oes
+ *
+ * Fixed ugly indentation of my last changes
+ *
+ * Revision 1.5 2001/05/23 10:39:05 oes
+ * - Added support for escaping the comment character
+ * in config files by a backslash
+ * - Added support for line continuation in config
+ * files
+ * - Fixed a buffer overflow bug with long config lines
+ *
+ * Revision 1.4 2001/05/22 18:56:28 oes
+ * CRLF -> LF
+ *
+ * Revision 1.3 2001/05/20 01:21:20 jongfoster
+ * Version 2.9.4 checkin.
+ * - Merged popupfile and cookiefile, and added control over PCRS
+ * filtering, in new "permissionsfile".
+ * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
+ * file error you now get a message box (in the Win32 GUI) rather
+ * than the program exiting with no explanation.
+ * - Made killpopup use the PCRS MIME-type checking and HTTP-header
+ * skipping.
+ * - Removed tabs from "config"
+ * - Moved duplicated url parsing code in "loaders.c" to a new funcition.
+ * - Bumped up version number.
+ *
+ * Revision 1.2 2001/05/17 23:01:01 oes
+ * - Cleaned CRLF's from the sources and related files
+ *
+ * Revision 1.1.1.1 2001/05/15 13:58:59 oes
+ * Initial import of version 2.9.3 source tree
