   9 # This will increase the version number and pre-release tag, according to the
  10 # current state of the source tree, and the function's first argument (called
  11 # |next| internally), which is how the caller tells what the next step should
  12 # be.
  13 #
  14 # The possible current source tree states are:
  15 # ''            The source is in a released state.
  16 # 'dev'         The source is in development.  This is the normal state.
  17 # 'alpha', 'alphadev'
  18 #               The source is undergoing a series of alpha releases.
  19 # 'beta', 'betadev'
  20 #               The source is undergoing a series of beta releases.
  21 # These states are computed from $PRE_LABEL and $TYPE
  22 #
  23 # The possible |next| values are:
  24 # 'alpha'       The source tree should move to an alpha release state, or
  25 #               stay there.  This trips the alpha / pre-release counter.
  26 # 'beta'        The source tree should move to a beta release state, or
  27 #               stay there.  This trips the beta / pre-release counter.
  28 # 'final'       The source tree should move to a final release (assuming it's
  29 #               currently in one of the alpha or beta states).  This turns
  30 #               off the alpha or beta states.
  31 # ''            The source tree should move to the next release.  The exact
  32 #               meaning depends on the current source state.  It may mean
  33 #               tripping the alpha / beta / pre-release counter, or increasing
  34 #               the PATCH number.
  35 #
  36 # 'minor'       The source tree should move to the next minor version.  This
  37 #               should only be used in the master branch when a release branch
  38 #               has been created.
  39 #
  40 # This function expects there to be a function called fixup_version(), which
  41 # SHOULD take the |next| as first argument, and SHOULD increase the label
  42 # counter or the PATCH number accordingly, but only when the current
  43 # state is "in development".
