* Revisions :
* $Log: loaders.c,v $
+ * Revision 1.8 2001/05/26 00:55:20 jongfoster
+ * Removing duplicated code. load_forwardfile() now uses create_url_spec()
+ *
+ * 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
