+/*++
+/* NAME
+/* fsstone 1
+/* SUMMARY
+/* measure directory operation overhead
+/* SYNOPSIS
+/* .fi
+/* \fBfsstone\fR [\fB-cr\fR] [\fB-s \fIsize\fR]
+/* \fImsg_count files_per_dir\fR
+/* DESCRIPTION
+/* The \fBfsstone\fR command measures the cost of creating, renaming
+/* and deleting queue files versus appending messages to existing
+/* files and truncating them after use.
+/*
+/* The program simulates the arrival of \fImsg_count\fR short messages,
+/* and arranges for at most \fIfiles_per_dir\fR simultaneous files
+/* in the same directory.
+/*
+/* Options:
+/* .IP \fB-c\fR
+/* Create and delete files.
+/* .IP \fB-r\fR
+/* Rename files twice (requires \fB-c\fR).
+/* .IP \fB-s \fIsize\fR
+/* Specify the file size in kbytes.
+/* DIAGNOSTICS
+/* Problems are reported to the standard error stream.
+/* BUGS
+/* The \fB-r\fR option renames files within the same directory.
+/* For a more realistic simulation, the program should rename files
+/* <i>between</i> directories, and should also have an option to use
+/* <i>hashed</i> directories as implemented with, for example, the
+/* \fBdir_forest\fR(3) module.
+/* LICENSE
+/* .ad
