\&\fBgc-analyze\fR prints an analysis of a \s-1GC\s0 memory dump to
standard out.
.PP
The memory dumps may be created by calling
\&\f(CW\*(C`gnu.gcj.util.GCInfo.enumerate(String namePrefix)\*(C'\fR from java
code. A memory dump will be created on an out of memory condition if
\&\f(CW\*(C`gnu.gcj.util.GCInfo.setOOMDump(String namePrefix)\*(C'\fR is called
before the out of memory occurs.
.PP
Running this program will create two files: \fITestDump001\fR and
\&\fITestDump001.bytes\fR.
