+.TH ovs\-parse\-leaks 8 "August 2010" "Open vSwitch" "Open vSwitch Manual"
+.
+.SH NAME
+Bovs\-parse\-leaks \- parses OVS leak checker log files
+.
+.SH SYNOPSIS
+\fBovs\-parse\-leaks\fR [\fIbinary\fR] \fB< \fIlog\fR
+.
+.SH DESCRIPTION
+Many Open vSwitch daemons accept a \fB\-\-check\-leaks\fR option that
+writes information about memory allocation and deallocation to a log
+file.  \fBovs\-parse\-leaks\fR parses log files produced by this
+option and prints a summary of the results.  The most interesting part
+of the output is a list of memory blocks that were allocated but not
+freed, which Open vSwitch developers can use to find and fix memory
+leaks.
+.PP
+The log file must be supplied on standard input.  The binary that
+produced the output should be supplied as the sole non-option
+argument.  For best results, the binary should have debug symbols.
+.
+.SH OPTIONS
+.TP
+\fB\-\-help\fR
+Prints a help usage message and exits.
+.SH BUGS
+The output can be hard to interpret, especially for a daemon that does
+not exit in normal operation.
+.PP
+\fBovs\-parse\-leaks\fR usually incorrectly reports one or more "bad
+frees of not-allocated address" errors at the beginning of output.
+These reflect frees of data that were allocated before the leak
+checker was turned on during program initialization.
