 # Description:
-#   This script automates the running of Synopsys SpyGlass linting for
-#   various Wally RISC-V configurations. It substitutes the WALLYVER value
-#   in the base project file and runs SpyGlass for a specified lint goal.
-#
-#   - Cleans out the lint-synopsys directory (if it exists)
-#   - Accepts one configurable linting goal
-#   - Iterates over multiple Wally configurations
-#   - Generates temporary .prj files for each run
+#   Automates Synopsys SpyGlass linting for Wally RISC-V configurations.
+#   Supports command-line options for custom goals and configs.
