+# Simple nine-packet LSP test for examples/minimal_lsp.rs
+# Usage (two tabs):
+#
+#   mkfifo /tmp/lsp_pipe          # one-time setup
+#   # tab 1 – run the server
+#   cat /tmp/lsp_pipe | cargo run --example minimal_lsp
+#
+#   # tab 2 – fire the packets (this script)
+#   bash examples/manual_test.sh          # blocks until server exits
+#
+# If you don’t use a second tab, run the script in the background:
+#
+#   bash examples/manual_test.sh &        # writer in background
+#   cat /tmp/lsp_pipe | cargo run --example minimal_lsp
+#
+# The script opens /tmp/lsp_pipe for writing (exec 3>) and sends each JSON
+# packet with a correct Content-Length header.
+#
+# One-liner alternative (single terminal, no FIFO):
+#
+#   cargo run --example minimal_lsp <<'EOF'
+#     … nine packets …
+#   EOF
+#
+# Both approaches feed identical bytes to minimal_lsp via stdin.
