-.TH dappprof 1m "$Date:: 2007-08-05 #$" "USER COMMANDS"
-.SH NAME
-dappprof \- profile user and lib function usage. Uses DTrace.
-.SH SYNOPSIS
-.B dappprof
-[\-acehoTU] [\-u lib] { \-p PID | command }
-.SH DESCRIPTION
-dappprof prints details on user and library call times for processes
-as a summary style aggragation. By default the user fuctions are
-traced, options can be used to trace library activity. Output can
-include function counts, elapsed times and on cpu times.
-
-The elapsed times are interesting, to help identify functions
-that take some time to complete (during which the process may
-have slept). CPU time helps us identify syscalls that
-are consuming CPU cycles to run.
-
-Since this uses DTrace, only the root user or users with the
-dtrace_kernel privilege can run this command.
-.SH OS
-Solaris
-.SH STABILITY
-stable - needs the pid provider.
