# - Returns a version string from Git |

# get_git_head_revision(<refspecvar> <hashvar> [ALLOW_LOOKING_ABOVE_CMAKE_SOURCE_DIR]) |

# Returns the refspec and sha hash of the current head revision |
||||
# |
||||
# git_describe(<var> [<additional arguments to git describe> ...]) |
||||
# |
||||
# Returns the results of git describe on the source tree, and adjusting |

# the output so that it tests false if an error occurs. |

# git_describe_working_tree(<var> [<additional arguments to git describe> ...]) |

# |

# Returns the results of git describe on the working tree (--dirty option), |

# git_get_exact_tag(<var> [<additional arguments to git describe> ...]) |

# Returns the results of git describe --exact-match on the source tree, |

# git_local_changes(<var>) |

# Returns either "CLEAN" or "DIRTY" with respect to uncommitted changes. |
