+
+NOTE TO DEVELOPERS
+
+The routines you write here must work closely with fixincl.c.
+
+Here are the rules:
+
+1.  Every test procedure name must be suffixed with "_test".
+    These routines will be referenced from inclhack.def, sans the suffix.
+
+2.  Use the "TEST_FOR_FIX_PROC_HEAD()" macro _with_ the "_test" suffix
+    (I cannot use the ## magic from ANSI C) for defining your entry point.
+
+3.  Put your test name into the FIX_TEST_TABLE
+
+4.  Do not write anything to stdout.  It may be closed.
+
+5.  Write to stderr only in the event of a reportable error
+    In such an event, call "exit(1)".
