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