+@command{gc-analyze} [@option{OPTION}] @dots{} [@var{file}]
+@ignore
+  [@option{-v}]
+  [@option{--verbose}]

+@c man end
+
+@c man begin DESCRIPTION gc-analyze
+
+@command{gc-analyze} prints an analysis of a GC memory dump to
+standard out.
+
+The memory dumps may be created by calling
+@code{gnu.gcj.util.GCInfo.enumerate(String namePrefix)} from java
+code.  A memory dump will be created on an out of memory condition if
+@code{gnu.gcj.util.GCInfo.setOOMDump(String namePrefix)} is called
+before the out of memory occurs.
+
+Running this program will create two files: @file{TestDump001} and
+@file{TestDump001.bytes}.
+
+@example
+import gnu.gcj.util.*;
+import java.util.*;
+
+public class GCDumpTest
+@{
+    static public void main(String args[])
+    @{
+        ArrayList<String> l = new ArrayList<String>(1000);
+        
+        for (int i = 1; i < 1500; i++) @{
+            l.add("This is string #" + i);
+        @}
+        GCInfo.enumerate("TestDump");
+    @}
+@}
+@end example
+
+The memory dump may then be displayed by running:
+
+@example
+gc-analyze -v TestDump001
+@end example
+
+@c FIXME: Add real information here.
+@c This really isn't much more than the --help output.

+
+@c man begin OPTIONS gc-analyze
+
+@table @gcctabopt
+@item --verbose

+Verbose output.
+
+@item -p @var{tool-prefix}
+Prefix added to the names of the @command{nm} and @command{readelf} commands.
+
+@item -d @var{directory}
+Directory that contains the executable and shared libraries used when
+the dump was generated.
+
+@item --help
