The README.md

Lock File

This class is intended to avoid having multiple instances of a certain process (like an upgrade, such as with cs_webdbupgrade) from "tripping" over each other. Create a lock file somewhere on the system (which is readable + writable), and remove it when the operation completes. The file should stay if there's a problem that keeps the operation from completing (because trying again would probably fail, or would make things worse)., (*1)

use crazedsanity\lockfile\LockFile;

$lock = new LockFile('/path/to/rw/dir', 'file.lock');

if(!$lock->is_lockfile_present()) {
    $lock->create_lockfile($upgradeWording);

    // ... do some stuff...
    // Only delete the lockfile if it all succeeded
    $lock->delete_lockfile();
}
else {
    throw new exception($lock->read_lockfile());
}

You may want to look at Web DB Upgrade for an implementation example., (*2)
