+ * Load parameters.
+ *
+ * This module provides suitable callback functions for the params
+ * module. It builds the internal table of service details which is
+ * then used by the rest of the server.
+ *
+ * To add a parameter:
+ *
+ * 1) add it to the global or service structure definition
+ * 2) add it to the parm_table
+ * 3) add it to the list of available functions (eg: using FN_GLOBAL_STRING())
+ * 4) If it's a global then initialise it in init_globals. If a local
+ * (ie. service) parameter then initialise it in the sDefault structure
+ *
+ *
+ * Notes:
+ * The configuration file is processed sequentially for speed. It is NOT
+ * accessed randomly as happens in 'real' Windows. For this reason, there
+ * is a fair bit of sequence-dependent code here - ie., code which assumes
+ * that certain things happen before others. In particular, the code which
+ * happens at the boundary between sections is delicately poised, so be
+ * careful!
