 # description: Makuosan(MAKUO for short) is a software \
 #              which transfer files to multiple servers simultaneously \
 #              using UDP multicast.
 #              (MAKUO consists of makuosan daemon and command line utility msync.\
 #              The makuosan should be run on every server in a cluster. \
 #              The makuo talk to makuosan daemon.)
