rm (rm-safe) is an alternative to shell /bin/rm, which supports pin or unpin operation to protect your data.

• rm help, display help info
• rm pin, pin directories to protect them
  rm pin: pin current directory
  rm pin [target]...: pin targets, if target is file, pin directory of target
  rm pin -r [target]...: pin targets recursively
• rm unpin, unpin directories to unprotect them
  rm unpin: like rm pin
rm unpin [target]...: like rm unpin [target]
rm unpin -r [target]...: like rm unpin -r [target]...
• rm [options] [target]..., absolutely works like shell /bin/rm, why? I use exec.Command('/bin/rm', args) to fullfill the deletion task.

go install will install rm to $GOPATH/bin, please make sure $GOPATH/bin appears before /bin, /usr/bin in $PATH.
