+ * 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!

+PARAMS.C
+
+Copyright (C) 1990, 1991, 1992, 1993, 1994 Karl Auer
+
+This module provides for streamlines retrieval of information from a
+Windows-like parameter files. There is a function which will search for
+all sections in the file and call a specified function with each. There is
+a similar function which will call a specified function for all parameters
+in a section. The idea is that you pass the addresses of suitable functions
+to a single function in this module which will then enumerate all sections,
+and within each section all parameters, to your program.
+
+Parameter files contain text lines (newline delimited) which consist of
+either a section name in square brackets or a parameter name, delimited
+from the parameter value by an equals sign. Blank lines or lines where the
+first non-whitespace character is a colon are ignored. All whitespace in
+section names and parameter names is compressed to single spaces. Leading
+and trailing whitespace on parameter names and parameter values is stripped.
+
+Only the first equals sign in a parameter line is significant - parameter
+values may contain equals signs, square brackets and semicolons. Internal
+whitespace is retained in parameter values. Parameter names may not start
+with a square bracket, an equals sign or a semicolon, for obvious reasons.
+
+A sample parameter file might look like this:
+
+[things]
+this=1
+that=2
+[other things]
+the other = 3
