+# Extract statistics from ftp daemon log.
+
+# Usage:
+# ftpstats [-m maxitems] [-s search] [file]
+# -m maxitems: restrict number of items in "top-N" lists, default 25.
+# -s string:   restrict statistics to lines containing this string.
+# Default file is /usr/adm/ftpd;  a "-" means read stdandard input.
+
+# The script must be run on the host where the ftp daemon runs.
+# (At CWI this is currently buizerd.)
