gitbrute - brute-force a git commit hash to a given prefix

gitbrute -prefix deadbeef

gitbrute amends the top commit in a git repository, altering commit-time and author-time to have the commit's hash start with the given prefix.

Specifies the hash prefix to search for. Obviously, the expected time required to find it grows exponentially with the prefix's length.
If the current commit already matches the prefix, it will be replaced by another one.
Specifies the level of parallelism; defaults to number of online processors at startup.
