   == DESCRIPTION ==
   Extracts metadata about the head revision from your repository.
   
   This program is meant to be used by project build systems to extract
  -properties that can be used in software version strings. It can emit
  -source files containing variable and macro definitions suitable for
  -use with C, C++, Java, sh, Python, Perl, Mac info.plist and other
  -types of files (see below for the full list).
  -
  -The generated source is written to standard output.

   This program can normally be called from anywhere within a repository
   copy.  Under bzr the copy must be of a branch, not a full multibranch
  
positive.code: *VCS_BASENAME*::
  The basename of the directory root.  For most VCSes this will simply
  be the basename of the repository root directory.  For Subversion,
  *autorevision* will navigate up though trunk, branches, and tags
  directories to find the actual root.
  
  *VCS_NUM*::
  A count of revisions between the current one and the initial
  
negative.code: If you specify a cache file, then when *autorevision* is run where no
  repository can be recognized, the values from the cache file will be
  used instead.  If a repository can be recognized, the cache is
  rewritten. This feature makes it possible for your build to run from
  an unpacked tarball that includes the cache file.
