A program for extracting version information useful in release/build scripting from repositories.

Supported repository types include git, hg, bzr, and svn. The record can be emitted in a ready-to-use form for C, C++, Java, bash, Python, Perl, lua, php, ini and others.

Emitted information includes the ID of the most recent commit, its branch, its date, and several other useful pieces of meta-information.

There is support for reading and writing a cache file so autorevision will remain useful during a build from an unpacked distribution tarball.

See the manual page, included in the distribution, for invocation details.
