+?S:nofile:
+?S:	This variable contains the number of file descriptors available to the
+?S:	process.
+?S:.
+?S:d_gettblsz:
+?S:	This variable conditionally handles remapping of the getdtablesize()
+?S:	subroutine to ulimit(4,0), or the NOFILE manifest constant.
+?S:.
+?S:tablesize:
+?S:	This variable contains either the 'NOFILE' constant or 'ulimit(4, 0L)'
+?S:	and is used as the remapped value for the getdtablesize() macro.
+?S:.
+?C:getdtablesize:
+?C:	This catches use of the getdtablesize() subroutine, and remaps it
+?C:	to either ulimit(4,0) or NOFILE, if getdtablesize() isn't available.
+?C:.
+?C:VAL_NOFILE:
+?C:	This symbol contains the number of file descriptors available to the
+?C:	process, as determined at configuration time. Unless a static constant
+?C:	is needed, you should rely on getdtablesize() to obtain that number.
