24 * This module provides suitable callback functions for the params
25 * module. It builds the internal table of section details which is
26 * then used by the rest of the server.
30 * 1) add it to the global_vars or local_vars structure definition
31 * 2) add it to the parm_table
32 * 3) add it to the list of available functions (eg: using FN_GLOBAL_STRING())
33 * 4) initialise it in the Defaults static structure
36 * The configuration file is processed sequentially for speed. For this
37 * reason, there is a fair bit of sequence-dependent code here - ie., code
38 * which assumes that certain things happen before others. In particular, the
39 * code which happens at the boundary between sections is delicately poised,
