[Dave Anderson]

Hi Daisuke,

Can you please format the crash-gcore-command-1.1.tar.gz file in
the same manner as crash-gcore-command-1.0.tar.gz?  Here is the
current version: 

# tar tvzmf crash-gcore-command-1.0.tar.gz
drwxrwxr-x hat/hat           0 2011-04-24 11:32 ./crash-gcore-command-1.0/

-rw-rw-r-- hat/hat       18015 2011-04-24 11:38 ./crash-gcore-command-1.0/COPYING
# 

Your new release just dumps all the files into the current directory:

# tar xvzmf crash-gcore-command-1.1.tar.gz
gcore.c
gcore.mk
libgcore/
libgcore/gcore_compat_x86.h
libgcore/gcore_coredump.c
libgcore/gcore_coredump_table.c
libgcore/gcore_defs.h
libgcore/gcore_dumpfilter.c
libgcore/gcore_elf_struct.c
libgcore/gcore_global_data.c
libgcore/gcore_regset.c
libgcore/gcore_verbose.c
libgcore/gcore_x86.c
