libfile-nfslock-perl - 1.29-2 main

Program based on the concept of hard linking of files being atomic across
NFS. This concept was mentioned in Mail::Box::Locker. Some ideas are
taken from there -- particularly the idea of creating a random local file,
hard linking a common file to the local file, and then checking the nlink
status.
.
File::NFSLock was written to be light, generic, and fast.
