## 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.
+See [INSTALL.md](./INSTALL.md) for detailed installation instructions.

-## Updating Versioneer
+## Known Limitations
-To upgrade your project to a new release of Versioneer, do the following:
+Some situations are known to cause problems for Versioneer. This details the
+most significant ones. More can be found on Github
+[issues page](https://github.com/warner/python-versioneer/issues).
-* 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
+### Subprojects
+
+Versioneer has limited support for source trees in which `setup.py` is not in
+the root directory (e.g. `setup.py` and `.git/` are *not* siblings). The are
+two common reasons why `setup.py` might not be in the root:
+
+* Source trees which contain multiple subprojects, such as
+ [Buildbot](https://github.com/buildbot/buildbot), which contains both
+ "master" and "slave" subprojects, each with their own `setup.py`,
+ `setup.cfg`, and `tox.ini`. Projects like these produce multiple PyPI
+ distributions (and upload multiple independently-installable tarballs).
+* Source trees whose main purpose is to contain a C library, but which also
+ provide bindings to Python (and perhaps other langauges) in subdirectories.
+
+Versioneer will look for `.git` in parent directories, and most operations
+should get the right version string. However `pip` and `setuptools` have bugs
+and implementation details which frequently cause `pip install .` from a
+subproject directory to fail to find a correct version string (so it usually
+defaults to `0+unknown`).
-### Upgrading to 0.16
+`pip install --editable .` should work correctly. `setup.py install` might
+work too.
-Nothing special.
+Pip-8.1.1 is known to have this problem, but hopefully it will get fixed in
+some later version.
-### Upgrading to 0.15
+[Bug #38](https://github.com/warner/python-versioneer/issues/38) is tracking
+this issue. The discussion in
+[PR #61](https://github.com/warner/python-versioneer/pull/61) describes the
+issue from the Versioneer side in more detail.
+[pip PR#3176](https://github.com/pypa/pip/pull/3176) and
+[pip PR#3615](https://github.com/pypa/pip/pull/3615) contain work to improve
+pip to let Versioneer work correctly.
-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.
+Versioneer-0.16 and earlier only looked for a `.git` directory next to the
+`setup.cfg`, so subprojects were completely unsupported with those releases.
-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.
+### Editable installs with setuptools <= 18.5
-### Upgrading to 0.14
+`setup.py develop` and `pip install --editable .` allow you to install a
+project into a virtualenv once, then continue editing the source code (and
+test) without re-installing after every change.
-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.
+"Entry-point scripts" (`setup(entry_points={"console_scripts": ..})`) are a
+convenient way to specify executable scripts that should be installed along
+with the python package.
-### Upgrading from 0.11 to 0.12
+These both work as expected when using modern setuptools. When using
+setuptools-18.5 or earlier, however, certain operations will cause
+`pkg_resources.DistributionNotFound` errors when running the entrypoint
+script, which must be resolved by re-installing the package. This happens
+when the install happens with one version, then the egg_info data is
+regenerated while a different version is checked out. Many setup.py commands
+cause egg_info to be rebuilt (including `sdist`, `wheel`, and installing into
+a different virtualenv), so this can be surprising.
-Nothing special.
+[Bug #83](https://github.com/warner/python-versioneer/issues/83) describes
+this one, but upgrading to a newer version of setuptools should probably
+resolve it.
-### Upgrading from 0.10 to 0.11
+### Unicode version strings
-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.
+While Versioneer works (and is continually tested) with both Python 2 and
+Python 3, it is not entirely consistent with bytes-vs-unicode distinctions.
+Newer releases probably generate unicode version strings on py2. It's not
+clear that this is wrong, but it may be surprising for applications when then
+write these strings to a network connection or include them in bytes-oriented
+APIs like cryptographic checksums.
+
+[Bug #71](https://github.com/warner/python-versioneer/issues/71) investigates
+this question.
+
