(pulled in via reachover makefile) suitable for measuring the
input to arbitrary pipes.
This is intended for use by sysinst.

+.Os
+.Sh NAME
+.Nm progress
+.Nd feed input to a command, displaying a progress bar
+.Sh SYNOPSIS
+.Nm
+.Op Fl z
+.Op Fl f Ar file
+.Op Fl l Ar length
+.Ar cmd
+.Op Ar args ...
+.Sh DESCRIPTION
+The
+.Nm
+utility opens a pipe to
+.Ar cmd
+and feeds an input stream into it, while displaying a progress bar to
+standard output.
+If no filename is specified,
+.Nm
+reads from standard input.
+Where feasible,
+.Nm
+.Xr fstat 2 Ns s
+the input to determine the length, so a time estimate can be calculated.
+.Pp
+If no length is specified or determined,
+.Nm
+simply displays a count of the data and the data rate.
+.Pp
+The options are as follows:
+.Bl -tag -width XlXlengthXX
+.It Fl f Ar file
+Read from the specified
+.Ar file
+instead of standard input.
+.It Fl l Ar length
+Use the specified length for the time estimate, rather than attempting to
+.Xr fstat 2
+the input.
+.It Fl z
+Filter the input through
+.Xr gzip 1 .
+If
+.Fl f
+is specified, calculate the length using
+.Ic gzip -l .
+.El
+.Sh EXIT STATUS
+.Nm
+exits 0 on success.
+.\" .Sh ENVIRONMENT
+.\" .Sh FILES
+.Sh EXAMPLES
+The command
+.Ic progress -zf file.tar.gz tar xf -
+will extract the
+.Pa file.tar.gz
+displaying the progress bar as time passes:
+.Bd -literal

+100% |*********************************|   680 KB  264.59 KB/s    00:00 ETA
+.Ed
+.Pp
+If it is preferred to monitor the progress of the decompression
+process (unlikely), then
+.Ic progress -f file.tar.gz tar zxf -
+could be used.
+.\".Sh DIAGNOSTICS
+.Sh SEE ALSO
+.Xr ftp 1
+.\" .Sh STANDARDS
+.Sh HISTORY
+.Nm
+first appeared in
+.Nx 1.6.1 .
+The dynamic progress bar display code is part of
+.Pa lukemftp .
+.Sh AUTHORS
+.Nm
+was written by
+.An John Hawkinson Aq jhawk%NetBSD.ORG@localhost .
+.Xr ftp 1 Ns 's
+dynamic progress bar was written by Luke Mewburn.
+.Sh BUGS
+Since the progress bar is displayed asynchronously, it may be
+difficult to read some error messages, both those produced by the
+pipeline, as well as those produced by
+.Nm
+itself.
+.Pp
+Under special circumstances,
+.Nm
+may have its output pipe prematurely closed.
+For example:
+.Bd -literal
+# < /dev/zero progress dd of=/dev/null
+ 26923 KB   26.19 MB/s progress: wrote -1 of 512 bytes to output pipe: Bad address
+# 53847+0 records in
+53847+0 records out
+27569664 bytes transferred in 0.997 secs (27652621 bytes/sec)
