+ * Revision 1.40 2002/03/08 17:46:04 jongfoster
+ * Fixing int/size_t warnings
+ *
+ * Revision 1.39 2002/03/07 03:46:17 oes
+ * Fixed compiler warnings
+ *
+ * Revision 1.38 2002/03/06 22:54:35 jongfoster
+ * Automated function-comment nitpicking.
+ *
+ * Revision 1.37 2002/03/03 15:07:49 oes
+ * Re-enabled automatic config reloading
+ *
+ * Revision 1.36 2002/01/22 23:46:18 jongfoster
+ * Moving edit_read_line() and simple_read_line() to loaders.c, and
+ * extending them to support reading MS-DOS, Mac and UNIX style files
+ * on all platforms.
+ *
+ * Modifying read_config_line() (without changing it's prototype) to
+ * be a trivial wrapper for edit_read_line(). This means that we have
+ * one function to read a line and handle comments, which is common
+ * between the initialization code and the edit interface.
+ *
* Revision 1.35 2002/01/17 21:03:08 jongfoster
* Moving all our URL and URL pattern parsing code to urlmatch.c.
