+/* NOTE: This is a header file, but it contains executable routines.
+   This is done this way because these routines are substantially
+   similar, but are not identical, for all ECOFF targets.
+
+   These are routines to swap the ECOFF symbolic information in and
+   out.  The routines are defined statically.  You can set breakpoints
+   on them in gdb by naming the including source file; e.g.,
+   'coff-mips.c':ecoff_swap_hdr_in.
+
+   Before including this header file, one of ECOFF_32 or ECOFF_64 must
+   be defined.  These are checked when swapping information that
+   depends upon the target size.  This code works for 32 bit and 64
+   bit ECOFF, but may need to be generalized in the future.
+
+   Some header file which defines the external forms of these
+   structures must also be included before including this header file.
+   Currently this is either coff/mips.h or coff/alpha.h.
+
+   If the symbol TEST is defined when this file is compiled, a
+   comparison is made to ensure that, in fact, the output is
+   bit-for-bit the same as the input.  Of course, this symbol should
+   only be defined when deliberately testing the code on a machine
+   with the proper byte sex and such.  */
