.buckversion, then you should create a file named
.nobuckcheckand add it to the root of your repository. The contents of the file do not matter.
Developers who are adding new features to Buck often need to create a
.nobuckcheck file if they are working on a project that makes use of
.buckversion. This way, the developer can test their changes to Buck on their project without running the risk of Buck trying to update itself and discarding the developer's changes.
