+"""Log in to the West Wood Club (PerfectGym) API and print the bearer token.
+
+The token is written to stdout (and nothing else), so it can be piped to a file:
+
+    python login.py > token.txt
+
+Credentials are read from the WESTWOOD_EMAIL and WESTWOOD_PASSWORD environment
+variables; any that are missing are prompted for on the terminal. Prompts and
+errors go to stderr, keeping stdout clean for the token.
