This algorithm\ntransfers the differences between 2 files without needing both files on\nthe same system.\n\nlibrsync is for building other programs that transfer files as efficiently\nas rsync. You can use librsync in a program you write to do backups,\ndistribute binary patches to programs, or sync directories to a server\nor between peers.\n\nlibrsync does not implement the rsync wire protocol or network functions.\n\nThis tree also produces the rdiff command-line tool that exposes the key\noperations of librsync: generating file signatures, generating the delta\nfrom a signature to a new file, and applying the delta to regenerate the\nnew file given the old file.\n","package_architecture":"amd64","stem":"librsync","readme":null,"dependencies":[{"path":"devel/popt","type":"library","package_spec":"","url":"/packages/current/devel/popt/"},{"path":"security/libb2","type":"library","package_spec":"","url":"/packages/current/security/libb2/"},{"path":"devel/cmake/core","type":"build","package_spec":"STEM->=4","url":"/packages/current/devel/cmake/core/"},{"path":"devel/ninja","type":"build","package_spec":"","url":"/packages/current/devel/ninja/"}],"reverse_dependencies":{"count":5,"url":"/packages/data/8e/8eb177afdfc2d8f30eb07ab98af69bc5225194f92098f2f09ece9c15cb93a24b.json"},"categories":["net"],"flavors":[],"only_for_architectures":[],"not_for_architectures":[]}}
