+# VMS .exe formats, both VAX and AXP (Greg Roelofs, newt@uchicago.edu)

+# GRR 950122:  I'm just guessing on these, based on inspection of the headers
+# of three executables each for Alpha and VAX architectures.  The VAX files
+# all had headers similar to this:

+# The AXP files all looked like this, except that the byte at offset 0x22
