.SH NAME

{ \-p PID | \-c cmd }
.SH DESCRIPTION
Filename and method names are printed if available.

Evolving - uses the DTrace Ruby provider, which may change
as additional features are introduced. Check Ruby/Readme
to see what version these scripts are based on.

.SH WARNING
This script is not 100% accurate; This prints libc malloc() byte
distributions by "recent" Ruby operation, which we hope will be usually
relevant. This is an experimental script that may be improved over time.
.PP
.SH DOCUMENTATION
See the DTraceToolkit for further documentation under the
Examples, Notes and Docs directories. The example files may be
especially useful as they aim to demonstrate how to interpret
the output.
