safefile
Go package safefile implements safe "atomic" saving of files.
Instead of truncating and overwriting the destination file, it creates a
temporary file in the same directory, writes to it, and then renames the
temporary file to the original name when calling Commit.
Installation
$ go get github.com/dchest/safefile
