USAGE="
USAGE: $0 version target

  This script will convert the specified version in DOC target files to the 'target'
  where target is one of:

      major
      minor
      build

  or an explicitly defined version number.

NOTE:

  Files prepped by this script should never target SNAPSHOT, as the docs should refer to release artifacts.
  If intending to update to/from snapshots, please add target files to release_version_update.sh instead.

EXAMPLES:

Update build version (1.0.0 -> 1.0.1)
    $0 1.0.0 build
Update minor version (1.2.3 -> 1.3.0)
    $0 1.2.3 minor
Update major version (1.2.3 -> 2.0.0)
    $0 1.2.3 major
