+## analyze_riscv_elf.py
+##
+## Written: james.stine@okstate.edu
+## Created: April 7, 2025
+##
+## Purpose: Analyze a RISC-V ELF file and report which instructions are used,
+##          along with their frequency. The script disassembles the ELF using
+##          riscv64-unknown-elf-objdump, filters real instructions (excluding
+##          pseudo-ops and section headers), and displays a histogram of 
+##          instruction use.Simulate a L1 D$ or I$ for comparison with Wally
+##
+## A component of the CORE-V-WALLY configurable RISC-V project.
