+# update.sh - Rebuild generated files from parse_pgen.py and pgen.pgen.
+#
+# These generated files are not actually used to generate themselves,
+# so the process isn't as tricky as it could otherwise be. (They are used
+# for testing and benchmarking.)
+#
+# How to change the pgen syntax:
+#
+# 1. Update the pgen_grammar and ASTBuilder in parse_pgen.py,
+#    and other downstream Python and Rust code appropriately.
+# 2. Make the corresponding edits to pgen.pgen. You can change it to
+#    use the new syntax that you're adding.
+# 3. Run this script.
+#
+# Even if something fails, fear not! It's usually pretty easy to fix stuff and
+# get to a fixpoint where everything passes.
