Exlock is a command line tool.
The purpose of this tool is to test / debug / tune the creation of other software.
Exlock opens in exclusive mode a file passed as parameter. Other processes accessing the file will get a error. The purpose of this tool is to simply evaluate which is the behavior in case of this error.
Let's you synchronize related scheduled jobs, which execute across many different machines. Instead of adding time padding between jobs (which can fail), use this utility. Please feel free to add more functions!
