-This file helps distutils-based projects manage their version number by just
-creating version-control tags.
-
-For developers who work from a VCS-generated tree (e.g. 'git clone' etc),
-each 'setup.py version', 'setup.py build', 'setup.py sdist' will compute a
-version number by asking your version-control tool about the current
-checkout. The version number will be written into a generated _version.py
-file of your choosing, where it can be included by your __init__.py
-
-For users who work from a VCS-generated tarball (e.g. 'git archive'), it will
-compute a version number by looking at the name of the directory created when
-te tarball is unpacked. This conventionally includes both the name of the
-project and a version number.
-
-For users who work from a tarball built by 'setup.py sdist', it will get a
-version number from a previously-generated _version.py file.
-
-As a result, loading code directly from the source tree will not result in a
-real version. If you want real versions from VCS trees (where you frequently
-update from the upstream repository, or do new development), you will need to
-do a 'setup.py version' after each update, and load code from the build/
-directory.
-
-You need to provide this code with a few configuration values:
-
- versionfile_source:
- A project-relative pathname into which the generated version strings
- should be written. This is usually a _version.py next to your project's
- main __init__.py file. If your project uses src/myproject/__init__.py,
- this should be 'src/myproject/_version.py'. This file should be checked
- in to your VCS as usual: the copy created below by 'setup.py
- update_files' will include code that parses expanded VCS keywords in
- generated tarballs. The 'build' and 'sdist' commands will replace it with
- a copy that has just the calculated version string.
-
- versionfile_build:
- Like versionfile_source, but relative to the build directory instead of
- the source directory. These will differ when your setup.py uses
- 'package_dir='. If you have package_dir={'myproject': 'src/myproject'},
- then you will probably have versionfile_build='myproject/_version.py' and
- versionfile_source='src/myproject/_version.py'.
-
- tag_prefix: a string, like 'PROJECTNAME-', which appears at the start of all
- VCS tags. If your tags look like 'myproject-1.2.0', then you
- should use tag_prefix='myproject-'. If you use unprefixed tags
- like '1.2.0', this should be an empty string.
-
- parentdir_prefix: a string, frequently the same as tag_prefix, which
- appears at the start of all unpacked tarball filenames. If
- your tarball unpacks into 'myproject-1.2.0', this should
- be 'myproject-'.
-
-To use it:
-
- 1: include this file in the top level of your project
- 2: make the following changes to the top of your setup.py:
- import versioneer
- versioneer.versionfile_source = 'src/myproject/_version.py'
- versioneer.versionfile_build = 'myproject/_version.py'
- versioneer.tag_prefix = '' # tags are like 1.2.0
- versioneer.parentdir_prefix = 'myproject-' # dirname like 'myproject-1.2.0'
- 3: add the following arguments to the setup() call in your setup.py:
- version=versioneer.get_version(),
- cmdclass=versioneer.get_cmdclass(),
- 4: run 'setup.py update_files', which will create _version.py, and will
- modify your __init__.py to define __version__ (by calling a function
- from _version.py)
- 5: modify your MANIFEST.in to include versioneer.py
- 6: add both versioneer.py and the generated _version.py to your VCS

+* Compatible With: python2.6, 2.7, 3.3, 3.4, 3.5, and pypy
+* [![Latest Version]
+(https://pypip.in/version/versioneer/badge.svg?style=flat)
+](https://pypi.python.org/pypi/versioneer/)
+* [![Build Status]
+(https://travis-ci.org/warner/python-versioneer.png?branch=master)
+](https://travis-ci.org/warner/python-versioneer)
+
+This is a tool for managing a recorded version number in distutils-based
+python projects. The goal is to remove the tedious and error-prone "update
+the embedded version string" step from your release process. Making a new
+release should be as easy as recording a new tag in your version-control
+system, and maybe making new tarballs.
+
+
+## Quick Install
+
+* `pip install versioneer` to somewhere to your $PATH
+* add a `[versioneer]` section to your setup.cfg (see below)
+* run `versioneer install` in your source tree, commit the results
+
+## Version Identifiers
+
+Source trees come from a variety of places:
+
+* a version-control system checkout (mostly used by developers)
+* a nightly tarball, produced by build automation
+* a snapshot tarball, produced by a web-based VCS browser, like github's
+ "tarball from tag" feature
+* a release tarball, produced by "setup.py sdist", distributed through PyPI
+
+Within each source tree, the version identifier (either a string or a number,
+this tool is format-agnostic) can come from a variety of places:
+
+* ask the VCS tool itself, e.g. "git describe" (for checkouts), which knows
+ about recent "tags" and an absolute revision-id
+* the name of the directory into which the tarball was unpacked
+* an expanded VCS keyword ($Id$, etc)
+* a `_version.py` created by some earlier build step
+
+For released software, the version identifier is closely related to a VCS
+tag. Some projects use tag names that include more than just the version
+string (e.g. "myproject-1.2" instead of just "1.2"), in which case the tool
+needs to strip the tag prefix to extract the version identifier. For
+unreleased software (between tags), the version identifier should provide
+enough information to help developers recreate the same tree, while also
+giving them an idea of roughly how old the tree is (after version 1.2, before
+version 1.3). Many VCS systems can report a description that captures this,
+for example `git describe --tags --dirty --always` reports things like
+"0.7-1-g574ab98-dirty" to indicate that the checkout is one revision past the
+0.7 tag, has a unique revision id of "574ab98", and is "dirty" (it has
+uncommitted changes.
+
+The version identifier is used for multiple purposes:
+
+* to allow the module to self-identify its version: `myproject.__version__`
+* to choose a name and prefix for a 'setup.py sdist' tarball
+
+## Theory of Operation
+
+Versioneer works by adding a special `_version.py` file into your source
+tree, where your `__init__.py` can import it. This `_version.py` knows how to
+dynamically ask the VCS tool for version information at import time.
+
+`_version.py` also contains `$Revision$` markers, and the installation
+process marks `_version.py` to have this marker rewritten with a tag name
+during the `git archive` command. As a result, generated tarballs will
+contain enough information to get the proper version.
+
+To allow `setup.py` to compute a version too, a `versioneer.py` is added to
+the top level of your source tree, next to `setup.py` and the `setup.cfg`
+that configures it. This overrides several distutils/setuptools commands to
+compute the version when invoked, and changes `setup.py build` and `setup.py
+sdist` to replace `_version.py` with a small static file that contains just
+the generated version data.
+
+## Installation
+
+First, decide on values for the following configuration variables:
+
+* `VCS`: the version control system you use. Currently accepts "git".
+
+* `style`: the style of version string to be produced. See "Styles" below for
+ details. Defaults to "pep440", which looks like
+ `TAG[+DISTANCE.gSHORTHASH[.dirty]]`.
+
+* `versionfile_source`:
+
+ A project-relative pathname into which the generated version strings should
+ be written. This is usually a `_version.py` next to your project's main
+ `__init__.py` file, so it can be imported at runtime. If your project uses
+ `src/myproject/__init__.py`, this should be `src/myproject/_version.py`.
+ This file should be checked in to your VCS as usual: the copy created below
+ by `setup.py setup_versioneer` will include code that parses expanded VCS
+ keywords in generated tarballs. The 'build' and 'sdist' commands will
+ replace it with a copy that has just the calculated version string.
+
+ This must be set even if your project does not have any modules (and will
+ therefore never import `_version.py`), since "setup.py sdist" -based trees
+ still need somewhere to record the pre-calculated version strings. Anywhere
+ in the source tree should do. If there is a `__init__.py` next to your
+ `_version.py`, the `setup.py setup_versioneer` command (described below)
+ will append some `__version__`-setting assignments, if they aren't already
+ present.
+
+* `versionfile_build`:
+
+ Like `versionfile_source`, but relative to the build directory instead of
+ the source directory. These will differ when your setup.py uses
+ 'package_dir='. If you have `package_dir={'myproject': 'src/myproject'}`,
+ then you will probably have `versionfile_build='myproject/_version.py'` and
+ `versionfile_source='src/myproject/_version.py'`.
+
+ If this is set to None, then `setup.py build` will not attempt to rewrite
+ any `_version.py` in the built tree. If your project does not have any
+ libraries (e.g. if it only builds a script), then you should use
+ `versionfile_build = None`. To actually use the computed version string,
+ your `setup.py` will need to override `distutils.command.build_scripts`
+ with a subclass that explicitly inserts a copy of
+ `versioneer.get_version()` into your script file. See
+ `test/demoapp-script-only/setup.py` for an example.
+
+* `tag_prefix`:
+
+ a string, like 'PROJECTNAME-', which appears at the start of all VCS tags.
+ If your tags look like 'myproject-1.2.0', then you should use
+ tag_prefix='myproject-'. If you use unprefixed tags like '1.2.0', this
+ should be an empty string, using either `tag_prefix=` or `tag_prefix=''`.
+
+* `parentdir_prefix`:
+
+ a optional string, frequently the same as tag_prefix, which appears at the
+ start of all unpacked tarball filenames. If your tarball unpacks into
+ 'myproject-1.2.0', this should be 'myproject-'. To disable this feature,
+ just omit the field from your `setup.cfg`.
+
+This tool provides one script, named `versioneer`. That script has one mode,
+"install", which writes a copy of `versioneer.py` into the current directory
+and runs `versioneer.py setup` to finish the installation.
+
+To versioneer-enable your project:
+
+* 1: Modify your `setup.cfg`, adding a section named `[versioneer]` and
+ populating it with the configuration values you decided earlier (note that
+ the option names are not case-sensitive):
+
+ ````
+ [versioneer]
+ VCS = git
+ style = pep440
+ versionfile_source = src/myproject/_version.py
+ versionfile_build = myproject/_version.py
+ tag_prefix =
+ parentdir_prefix = myproject-
+ ````
+
+* 2: Run `versioneer install`. This will do the following:
+
+ * copy `versioneer.py` into the top of your source tree
+ * create `_version.py` in the right place (`versionfile_source`)
+ * modify your `__init__.py` (if one exists next to `_version.py`) to define
+ `__version__` (by calling a function from `_version.py`)
+ * modify your `MANIFEST.in` to include both `versioneer.py` and the
+ generated `_version.py` in sdist tarballs
+
+ `versioneer install` will complain about any problems it finds with your
+ `setup.py` or `setup.cfg`. Run it multiple times until you have fixed all
+ the problems.
+
+* 3: add a `import versioneer` to your setup.py, and add the following
+ arguments to the setup() call:
+
+ version=versioneer.get_version(),
+ cmdclass=versioneer.get_cmdclass(),
+
+* 4: commit these changes to your VCS. To make sure you won't forget,
+ `versioneer install` will mark everything it touched for addition using
+ `git add`. Don't forget to add `setup.py` and `setup.cfg` too.
+
+## Post-Installation Usage
+
+Once established, all uses of your tree from a VCS checkout should get the
+current version string. All generated tarballs should include an embedded
+version string (so users who unpack them will not need a VCS tool installed).
+
+If you distribute your project through PyPI, then the release process should
+boil down to two steps:
+
+* 1: git tag 1.0
+* 2: python setup.py register sdist upload
+
+If you distribute it through github (i.e. users use github to generate
+tarballs with `git archive`), the process is:
+
+* 1: git tag 1.0
+* 2: git push; git push --tags
+
+Versioneer will report "0+untagged.NUMCOMMITS.gHASH" until your tree has at
+least one tag in its history.
+
+## Version-String Flavors
+
+Code which uses Versioneer can learn about its version string at runtime by
+importing `_version` from your main `__init__.py` file and running the
+`get_versions()` function. From the "outside" (e.g. in `setup.py`), you can
+import the top-level `versioneer.py` and run `get_versions()`.
+
+Both functions return a dictionary with different flavors of version
+information:
+
+* `['version']`: A condensed version string, rendered using the selected
+ style. This is the most commonly used value for the project's version
+ string. The default "pep440" style yields strings like `0.11`,
+ `0.11+2.g1076c97`, or `0.11+2.g1076c97.dirty`. See the "Styles" section
+ below for alternative styles.
+
+* `['full-revisionid']`: detailed revision identifier. For Git, this is the
+ full SHA1 commit id, e.g. "1076c978a8d3cfc70f408fe5974aa6c092c949ac".
+
+* `['dirty']`: a boolean, True if the tree has uncommitted changes. Note that
+ this is only accurate if run in a VCS checkout, otherwise it is likely to
+ be False or None
+
+* `['error']`: if the version string could not be computed, this will be set
+ to a string describing the problem, otherwise it will be None. It may be
+ useful to throw an exception in setup.py if this is set, to avoid e.g.
+ creating tarballs with a version string of "unknown".
+
+Some variants are more useful than others. Including `full-revisionid` in a
+bug report should allow developers to reconstruct the exact code being tested
+(or indicate the presence of local changes that should be shared with the
+developers). `version` is suitable for display in an "about" box or a CLI
+`--version` output: it can be easily compared against release notes and lists
+of bugs fixed in various releases.
+
+The installer adds the following text to your `__init__.py` to place a basic
+version in `YOURPROJECT.__version__`:
+
+ from ._version import get_versions
+ __version__ = get_versions()['version']
+ del get_versions
+
+## Styles
+
+The setup.cfg `style=` configuration controls how the VCS information is
+rendered into a version string.
+
+The default style, "pep440", produces a PEP440-compliant string, equal to the
+un-prefixed tag name for actual releases, and containing an additional "local
+version" section with more detail for in-between builds. For Git, this is
+TAG[+DISTANCE.gHEX[.dirty]] , using information from `git describe --tags
+--dirty --always`. For example "0.11+2.g1076c97.dirty" indicates that the
+tree is like the "1076c97" commit but has uncommitted changes (".dirty"), and
+that this commit is two revisions ("+2") beyond the "0.11" tag. For released
+software (exactly equal to a known tag), the identifier will only contain the
+stripped tag, e.g. "0.11".
+
+Other styles are available. See details.md in the Versioneer source tree for
+descriptions.
+
+## Debugging
+
+Versioneer tries to avoid fatal errors: if something goes wrong, it will tend
+to return a version of "0+unknown". To investigate the problem, run `setup.py
+version`, which will run the version-lookup code in a verbose mode, and will
+display the full contents of `get_versions()` (including the `error` string,
+which may help identify what went wrong).
+
+## Updating Versioneer
+
+To upgrade your project to a new release of Versioneer, do the following:
+
+* install the new Versioneer (`pip install -U versioneer` or equivalent)
+* edit `setup.cfg`, if necessary, to include any new configuration settings
+ indicated by the release notes
+* re-run `versioneer install` in your source tree, to replace
+ `SRC/_version.py`
+* commit any changed files
+
+### Upgrading to 0.16
+
+Nothing special.
+
+### Upgrading to 0.15
+
+Starting with this version, Versioneer is configured with a `[versioneer]`
+section in your `setup.cfg` file. Earlier versions required the `setup.py` to
+set attributes on the `versioneer` module immediately after import. The new
+version will refuse to run (raising an exception during import) until you
+have provided the necessary `setup.cfg` section.
+
+In addition, the Versioneer package provides an executable named
+`versioneer`, and the installation process is driven by running `versioneer
+install`. In 0.14 and earlier, the executable was named
+`versioneer-installer` and was run without an argument.
+
+### Upgrading to 0.14
-import os, sys, re
-from distutils.core import Command
-from distutils.command.sdist import sdist as _sdist
-from distutils.command.build import build as _build
+0.14 changes the format of the version string. 0.13 and earlier used
+hyphen-separated strings like "0.11-2-g1076c97-dirty". 0.14 and beyond use a
+plus-separated "local version" section strings, with dot-separated
+components, like "0.11+2.g1076c97". PEP440-strict tools did not like the old
+format, but should be ok with the new one.
-versionfile_source = None
-versionfile_build = None
-tag_prefix = None
-parentdir_prefix = None
+### Upgrading from 0.11 to 0.12
-VCS = "git"
-IN_LONG_VERSION_PY = False
+Nothing special.
+### Upgrading from 0.10 to 0.11
-LONG_VERSION_PY = '''
-IN_LONG_VERSION_PY = True
+You must add a `versioneer.VCS = "git"` to your `setup.py` before re-running
+`setup.py setup_versioneer`. This will enable the use of additional
+version-control systems (SVN, etc) in the future.
+
+## Future Directions
+
+This tool is designed to make it easily extended to other version-control
+systems: all VCS-specific components are in separate directories like
+src/git/ . The top-level `versioneer.py` script is assembled from these
+components by running make-versioneer.py . In the future, make-versioneer.py
+will take a VCS name as an argument, and will construct a version of
+`versioneer.py` that is specific to the given VCS. It might also take the
+configuration arguments that are currently provided manually during
+installation by editing setup.py . Alternatively, it might go the other
+direction and include code from all supported VCS systems, reducing the
+number of intermediate scripts.
