+@end format
+
+@c man begin DESCRIPTION gcore
+Generate a core dump of a running program with process ID @var{pid}.
+Produced file is equivalent to a kernel produced core file as if the process
+crashed (and if @kbd{ulimit -c} were used to set up an appropriate core dump
+limit).  Unlike after a crash, after @command{gcore} the program remains
+running without any change.

+@c man begin OPTIONS gcore
+@table @env
+@item -o @var{filename}
+The optional argument
+@var{filename} specifies the file name where to put the core dump.
+If not specified, the file name defaults to @file{core.@var{pid}},
+where @var{pid} is the running program process ID.
