* This module provides suitable callback functions for the params
- * module. It builds the internal table of service details which is
+ * module. It builds the internal table of section 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
+ * 1) add it to the global_vars or local_vars 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
- *
+ * 4) initialise it in the Defaults static stucture
*
* 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!
