+# Finger protocol adapter for Chawan. Requires curl.
+# (It does *not* work without the environment variables MAPPED_URI_*, so no
+# w3m support.)
+#
+# Usage: put this script in your cgi-bin folder, then add the following line to
+# your urimethodmap:
+#
+# finger: /cgi-bin/cha-finger?%s
+#
+# Note: the Chawan default configuration already does this, so normally you
+# don't need to do anything to use the finger protocol.
