-### Prerequisite
-* [ ] Make sure your problem is not listed in [the common build problems](https://github.com/pyenv/pyenv/wiki/Common-build-problems).
-* [ ] Make sure no duplicated issue has already been reported in [the pyenv issues](https://github.com/pyenv/pyenv/issues). You should look for closed issues, too.
-* [ ] Make sure you are not asking us to help solving your specific issue.
-  * GitHub issues is opened mainly for development purposes. If you want to ask someone to help solving your problem, go to some community site like [Gitter](https://gitter.im/yyuu/pyenv), [StackOverflow](https://stackoverflow.com/questions/tagged/pyenv), etc.
-* [ ] Make sure your problem is not derived from packaging (e.g. [Homebrew](https://brew.sh)).
-  * Please refer to the package documentation for the installation issues, etc.
-* [ ] Make sure your problem is not derived from plugins.
-  * This repository is maintaining `pyenv` and the default `python-build` plugin only. Please refrain from reporting issues of other plugins here.

+### Prerequisites
+* [ ] Make sure your problem is not listed in [the common build problems](https://github.com/pyenv/pyenv/wiki/Common-build-problems).
+* [ ] Make sure no duplicated issue has already been reported in [the pyenv issues](https://github.com/pyenv/pyenv/issues?q=is%3Aissue). For build errors, a reported issue typically mentions a key error message. This key error message is often not in the 10 last build log lines reported to the console but is rather earlier in the build log -- typically, it's the first error message encountered in the log.
+* [ ] Make sure you are reporting a problem in Pyenv and not seeking consultation with Pyenv usage.
+  * GitHub issues are intended mainly for Pyenv development purposes. If you are seeking help with Pyenv usage, check [Pyenv documentation](https://github.com/pyenv/pyenv?tab=readme-ov-file#simple-python-version-management-pyenv), go to a user community site like [Gitter](https://gitter.im/yyuu/pyenv), [StackOverflow](https://stackoverflow.com/questions/tagged/pyenv), etc, or to [Discussions](https://github.com/orgs/pyenv/discussions).

+
+### Describe the bug
+A clear and concise description of what the bug is.
+Do specify what the expected behaviour is if that's not obvious from the bug's nature.
+
+#### Reproduction steps
+Listing the commands to run in a new console session and their output is usually sufficient.
+Please use a Markdown code block (three backticks on a line by themselves before and after the text) to denote a console output excerpt.
+Usually not needed for build errors (since the arguments can already be seen in the debug trace) unless you are using an unusual invocation (e.g. setting environment variables that affect the build).
+
+#### Diagnostic details
+- [ ] Platform information (e.g. Ubuntu Linux 24.04):
+- [ ] OS architecture (e.g. amd64):
+- [ ] pyenv version:
+- [ ] Python version:
+- [ ] C Compiler information (e.g. gcc 7.3): 
+- [ ] Please attach the debug trace of the failing command as a [gist](https://gist.github.com/):
+  * Run `env PYENV_DEBUG=1 <faulty command> 2>&1 | tee trace.log` and attach `trace.log`. E.g. if you have a problem with installing Python, run `env PYENV_DEBUG=1 pyenv install -v <version> 2>&1 | tee trace.log` (note the `-v` option to `pyenv install`).
+- [ ] If you have a problem with installing Python, please also attach `config.log` from the build directory
+  * The build directory is reported after the "BUILD FAILED" message and is usually under `/tmp`.
+- [ ] If the build succeeds but the problem is still with the build process (e.g. the resulting Python is missing a feature), please attach
+  * the debug trace from reinstalling the faulty version with `env PYENV_DEBUG=1 pyenv install -f -k -v <version> 2>&1 | tee trace.log`
+  * `config.log` from the build directory. When using `pyenv install` with `-k` as per above, the build directory will be under `$PYENV_ROOT/sources`.
+- [ ] If the problem happens in another Pyenv invocation, turn on debug logging by setting `PYENV_DEBUG=1`, e.g. `env PYENV_DEBUG=1 pyenv local 3.6.4`, and attach the resulting trace as a gist
+- [ ] If the problem happens outside of a Pyenv invocation, get the debug trace like this:
+     ```
+     export PYENV_DEBUG=1
+     # for Bash
+     export PS4='+(${BASH_SOURCE}:${LINENO}): ${FUNCNAME[0]:+${FUNCNAME[0]}(): }'
+     # for Zsh
+     export PS4='+(%x:%I): %N(%i): '
+
+     set -x
+     <reproduce the problem>
+     set +x
+     ```

 ### Prerequisite
 * [ ] Please consider implementing the feature as a hook script or plugin as a first step.
   * pyenv has some powerful support for plugins and hook scripts. Please refer to [Authoring plugins](https://github.com/pyenv/pyenv/wiki/Authoring-plugins) for details and try to implement it as a plugin if possible.
-* [ ] Please consider contributing the patch upstream to [rbenv](https://github.com/rbenv/rbenv), since we have borrowed most of the code from this project.
-  * We are occasionally importing the changes from rbenv. In general, you can expect some changes made in rbenv will be imported to pyenv too, eventually.
-  * Generally speaking, we sometimes don't prefer to make some change in the core to keep compatibility with rbenv.

+General guidance
+================
+
+* The usual principles of respecting existing conventions and making sure that your changes
+  are in line with the overall product design apply when contributing code to Pyenv.
+
+* We are limited to Bash 3.2 features
+
+  That's because that's the version shipped with MacOS.
+  (They didn't upgrade past it and switched to Zsh because later versions
+  are covered by GPLv3 which has additional restrictions unacceptable for Apple.)
+
+  You can still add performance optimizations etc that take advantage of newer Bash features
+  as long as there is a fallback execution route for Bash 3.
+
+Formatting PRs
+==============
+
+We strive to keep commit history one-concern-per-commit to keep it meaningful and easy to follow.
+If a pull request (PR) addresses a single concern (the typical case), we usually squash commits
+from it together when merging so its commit history doesn't matter.
+If however a PR addresses multiple separate concerns, each of them should be presented as a separate commit.
+Adding multiple new Python releases of the same flavor is okay with either a single or multiple commits.
+
+
+Authoring installation scripts
+==============================
+
+Adding new Python release support
+---------------------------------
+
+The easiest way to add support for a new Python release is to copy the script from the previous one
+and adjust it as necessary. In many cases, just changing version numbers, URLs and hashes is enough.
+Do pay attention to other "magic numbers" that may be present in a script --
+e.g. the set of architectures and OS versions supported by a release -- since those change from time to time, too.
+
+Make sure to also copy any patches for the previous release that still apply to the new one.
+Typically, a patch no longer applies if it addresses a problem that's already fixed in the new release.
+
+For prereleases, we only create an entry for the latest prerelease in a specific version line.
+When submitting a newer prerelease, replace the older one.
+
+
+Adding version-specific fixes/patches
+-------------------------------------
+
+We accept fixes to issues in specific Python releases that prevent users from using them with Pyenv.
+
+In the default configuration for a Python release, we strive to provide as close to vanilla experience as practical,
+to maintain [the principle of the least surprise](https://en.wikipedia.org/wiki/Principle_of_least_astonishment).
+As such, any such fixes:
+
+* Must not break or degrade (e.g. disable features) the build in any of the environments that the release officially supports
+* Must not introduce incompatibilities with the vanilla release (including binary incompatibilities)
+* Should not patch things unnecessarily, to minimize the risk of the aforementioned undesirable side effects.
+  * E.g. if the fix is for a specific environment, its logic ought to only fire in this specific environment and not touch execution paths for other environments.
+  * As such, it's advisable to briefly explain in the PR what each added patch does and why it is necessary to fix the declared problem
+
+Generally, version-specific fixes belong in the scripts for the affected releases and/or patches for them -- this guarantees that their effect is limited to only those releases.
+
+<h3>Backporting upstream patches</h3>
+
+Usually, this is the easiest way to backport a fix for a problem that is fixed in a newer release.
+
+* Clone Python, check out the tag for the appropriate release and create a branch
+* Apply existing patches if there are any (with either `patch` or `git am`) and commit
+* Cherry-pick the upstream commit that fixes the problem in a newer release
+* Commit and `git format-patch`
+* Commit the generated patch file into Pyenv, test your changes and submit a PR
+
+
+Deprecation policy
+------------------
+
+We do not provide official support for EOL releases and environments or otherwise provide any kind of extended support for old Python releases.
+
+We do however accept fixes from interested parties that would allow running older, including EOL, releases in environments that they do not officially support.
+In addition to the above requirements for release-specific fixes,
+
+* Such a fix must not add maintenance burden (e.g. add new logic to `python-build` that has to be kept there indefinitely)
+  * Unless the added logic is useful for both EOL and non-EOL releases. In this case, it will be considered as being primarily an improvement for non-EOL releases.
+* Support is provided on a "best effort" basis: we do not actively maintain these fixes but won't actively break them, either, and will accept any corrections.
+  Since old releases never change, it's pretty safe to assume that the fixes will continue to work until a later version
+  of an environment introduces further incompatible changes.
+
+
+Advanced changes / adding new Python flavor support
+---------------------------------------------------
+
+An installation script is sourced from `python-build`. All installation scripts are based on the same logic:
+
+1. Select the source to download and other variable parameters as needed.
+
+   This includes showing an error if the user's environment (OS, architecture) is not supported by the release.
+   Binary releases that only officially support specific distro(s) typically show a warning in other distros instead.
+
+2. Run one of the `install_*` shell functions
+
+`install_*` shell functions defined in `python-build` install Python from different kinds of sources -- compressed package (binary or source), upstream installation script, VCS checkout. Pick one that's the most appropriate for your packaging.
+
+Each of them accepts a couple of function-specific arguments which are followed by arguments that constitute the build sequence. Each `<argument>` in the build sequence corresponds to the `install_*_<argument>` function in `python-build`. Check what's available and add any functions with logic specific to your flavor if needed.
+
+We strive to keep out of `python-build` parts of build logic that are release-specific and/or tend to change abruptly between releases -- e.g. sets of supported architectures and other software's versions. This results in logic duplication between installation scripts -- but since old releases never change once released, this doesn't really add to the maintenance burden. As a rule of thumb, `python-build` can host parts of logic that are expected to stay the same for an indefinite amount of time -- for an entire Python flavor or release line.

+Creating a release
+==================
+
+The release of the new version of Pyenv is done via GitHub Releases.
+
+Release checklist:
+* Start [drafting a new release on GitHub](https://github.com/pyenv/pyenv/releases) to generate a summary of changes.  
+Type the would-be tag name in the "Choose a tag" field and press "Generate release notes"
+  * The summary may need editing. E.g. rephrase entries, delete/merge entries that are too minor or irrelevant to the users (e.g. typo fixes, CI)
+* Add a sponsors section to the release notes by running:
+  ```bash
+  .github/scripts/generate_release_notes_sponsors.py
+  ```
+  Paste the output at the end of the release notes.
+  * This lists new GitHub Sponsors and OpenCollective backers since the last release or within the last month, whichever is longer.
+  * The GitHub Sponsors query requires the `gh` CLI with the `read:user` scope.
+  * If OpenCollective is unavailable, pass `--skip-opencollective` and add those backers manually.
+* Update `CHANGELOG.md` with the new version number and the edited summary (only the changes section)
+* Push the version number in `libexec/pyenv---version` and `plugins/python-build/bin/python-build`
+  * Minor version is pushed if there are significant functional changes (not e.g. bugfixes/formula adaptations/supporting niche use cases).
+  * Major version is pushed if there are breaking changes
+* Commit the changes locally into `master`
+* Create a new tag locally with the same name as specified in the new release window
+* Push the changes including the tag
+* In the still open new release window, press "Publish release". The now-existing tag will be used.

+To \fBdisable\fR pyenv managing your Python versions, simply remove the \fBpyenv init\fR line from your shell startup configuration\. This will remove pyenv shims directory from PATH, and future invocations like \fBpython\fR will execute the system Python version, as before pyenv\.

+\fBDepend on Python itself\.\fR pyenv was made from pure shell scripts\. There is no bootstrap problem of Python\.
+.IP \(bu 4
+\fBNeed to be loaded into your shell\.\fR Instead, pyenv's shim approach works by adding a directory to your \fB$PATH\fR\.
+.IP \(bu 4
+\fBManage virtualenv\.\fR Of course, you can create virtualenv  yourself, or pyenv\-virtualenv  to automate the process\.
+.SH "How It Works"
+At a high level, pyenv intercepts Python commands using shim executables injected into your \fBPATH\fR, determines which Python version has been specified by your application, and passes your commands along to the correct Python installation\.
+.SS "Understanding PATH"
+When you run a command like \fBpython\fR or \fBpip\fR, your operating system searches through a list of directories to find an executable file with that name\. This list of directories lives in an environment variable called \fBPATH\fR, with each directory in the list separated by a colon:
+.IP "" 4
+.nf
+/usr/local/bin:/usr/bin:/bin
+.fi
+.IP "" 0
+.P
+Directories in \fBPATH\fR are searched from left to right, so a matching executable in a directory at the beginning of the list takes precedence over another one at the end\. In this example, the \fB/usr/local/bin\fR directory will be searched first, then \fB/usr/bin\fR, then \fB/bin\fR\.
+.SS "Understanding Shims"
+pyenv works by inserting a directory of \fIshims\fR at the front of your \fBPATH\fR:
+.IP "" 4
+.nf
+$(pyenv root)/shims:/usr/local/bin:/usr/bin:/bin
+.fi
+.IP "" 0
+.P
+Through a process called \fIrehashing\fR, pyenv maintains shims in that directory to match every Python command (\fBpython\fR,\fBpip\fR,etc...) across every installed version of Python 
+.P
+Shims are lightweight executables that simply pass your command along to pyenv\. So with pyenv installed, when you run, say, \fBpip\fR, your operating system will do the following:
+.IP \(bu 4
+Search your \fBPATH\fR for an executable file named \fBpip\fR
+.IP \(bu 4
+Find the pyenv shim named \fBpip\fR at the beginning of your \fBPATH\fR
+.IP \(bu 4
+Run the shim named \fBpip\fR, which in turn passes the command along to pyenv
+.IP "" 0
+.SS "Choosing the Python Version"
+When you execute a shim, pyenv determines which Python version to use by reading it from the following sources, in this order:
+.IP "1." 4
+The \fBPYENV_VERSION\fR environment variable (if specified)\. You can use the \fBpyenv shell\fR command to set this environment variable in your current shell session\.
+.IP "2." 4
+The application\-specific \fB\.python\-version\fR file in the current directory (if present)\. You can modify the current directory's \fB\.python\-version\fR file with the \fBpyenv local\fR command\.
+.IP "3." 4
+The first \fB\.python\-version\fR file found (if any) by searching each parent directory, until reaching the root of your filesystem\.
+.IP "4." 4
+The global \fB$(pyenv root)/version\fR file\. You can modify this file using the \fBpyenv global\fR  command\. If the global version file is not present, pyenv assumes you want to use the "system" Python\. (In other words, whatever version would run if pyenv weren't in your \fBPATH\fR\.)
+.IP "" 0
+.P
+.nh
+\fBNOTE:\fR You can activate multiple versions at the same time, including multiple versions of Python2 or Python3 simultaneously\. This allows for parallel usage of Python2 and Python3, and is required with tools like \fBtox\fR\. For example, to set your path to first use your \fBsystem\fR Python and Python3 (set to 2\.7\.9 and 3\.4\.2 in this example), but also have Python 3\.3\.6, 3\.2, and 2\.5 available on your \fBPATH\fR, one would first \fBpyenv install\fR the missing versions, then set \fBpyenv global system 3\.3\.6 3\.2 2\.5\fR\. At this point, one should be able to find the full executable path to each of these using \fBpyenv which\fR, e\.g\. \fBpyenv which python2\.5\fR (should display \fB$(pyenv root)/versions/2\.5/bin/python2\.5\fR), or \fBpyenv which python3\.4\fR (should display path to system Python3)\. You can also specify multiple versions in a \fB\.python\-version\fR file, separated by newlines or any whitespace\.
+hy
+.SS "Locating the Python Installation"
+Once pyenv has determined which version of Python your application has specified, it passes the command along to the corresponding Python installation\.
+.P
+Each Python version is installed into its own directory under 
+.nf
+\fB$(pyenv root)/versions\fR\.
+.fi
+.P
+For example, you might have these versions installed:
+.IP \(bu 4
+\fB$(pyenv root)/versions/2\.7\.8/\fR
+.IP \(bu 4
+\fB$(pyenv root)/versions/3\.4\.2/\fR
+.IP \(bu 4
+\fB$(pyenv root)/versions/pypy\-2\.4\.0/\fR
+.IP "" 0
+.P
+As far as pyenv is concerned, version names are simply the directories in \fB$(pyenv root)/versions\fR\.
+.SS "Managing Virtual Environments"
+There is a pyenv plugin named pyenv\-virtualenv which comes with various features to help pyenv users to manage virtual environments created by virtualenv or Anaconda\. Because the \fBactivate\fR script of those virtual environments are relying on mutating \fB$PATH\fR variable of user's interactive shell, it will intercept pyenv's shim style command execution hooks\. We'd recommend to install pyenv\-virtualenv as well if you have some plan to play with those virtual environments\.
+
+.SH "Advanced Configuration"
+Skip this section unless you must know what every line in your shell profile is doing\.
+.P
+\fBpyenv init\fR is the only command that crosses the line of loading extra commands into your shell\. Coming from rvm, some of you might be opposed to this idea\. Here's what \fBpyenv init\fR actually does:
+.IP "1." 4
+\fBSets up your shims path\.\fR This is the only requirement for pyenv to function properly\. You can do this by hand by prepending \fB$(pyenv root)/shims\fR to your \fB$PATH\fR\.
+.IP "2." 4
+\fBRehashes shims\.\fR From time to time you'll need to rebuild your shim files\. Doing this on init makes sure everything is up to date\. You can always run \fBpyenv rehash\fR manually\.
+You can disable this functionality by adding \fB--no-rehash\fR to the end of your \fBpyenv init\fR command line.
+.IP "3." 4
+\fBInstalls the sh dispatcher\.\fR This bit is also optional, but allows pyenv and plugins to change variables in your current shell, making commands like \fBpyenv shell\fR possible\. The sh dispatcher doesn't do anything crazy like override \fBcd\fR or hack your shell prompt, but if for some reason you need \fBpyenv\fR to be a real script rather than a shell function, you can safely skip it\.

+# pyenv-binary (experimental)
+
+Package an installed Python version into a relocatable archive that can be
+installed on another machine.
+
+This is experimental and intentionally decoupled: it does not change
+`pyenv install` or any other command. You drive it explicitly through
+`pyenv binary`. Run `pyenv binary <command> --help` for details on a command.
+
+## Portability
+
+An archive is portable across machines that share its build platform (OS,
+architecture and a compatible libc) and have the recorded system libraries. It
+is not portable across, say, glibc and musl, or to an older glibc; the platform
+and dependency metadata exist to catch that.
+
+## Commands
+
+### `pyenv binary package [-v|--verbose] <version>[:<entry>] --archive-base-url <url>`
+
+Installs `<version>` from source under a separate name, packages that install
+with `save`, then emits a python-build definition for it with
+`generate-installer`. With no explicit entry, the name is generated from the
+current platform, platform version and architecture. An explicit entry keeps
+the existing custom-build workflow.
+
+Pass `-v` to show build progress from `pyenv install`.
+
+```sh
+pyenv binary package 3.12.7 \
+  --archive-base-url https://example.com/binaries
+# On Debian 12 x86_64, writes 3.12.7-debian-12-x86_64.tar.gz,
+# its .meta file and a `3.12.7-debian-12-x86_64' definition.
+
+pyenv binary package 3.12.7:company-python \
+  --archive-base-url https://example.com/binaries
+```
+
+The archive, metadata and definition land in the current directory, named after
+the entry. Host the archive under `<url>` and drop the definition into
+python-build's definition directory.
+
+### `pyenv binary package-name <version>`
+
+Prints the automatically generated entry name without building anything. Linux
+uses the distribution name and version, macOS uses the macOS version, and other
+systems use the name and release reported by `uname`. All names include the
+architecture.
+
+```sh
+pyenv binary package-name 3.12.7
+# 3.12.7-debian-12-x86_64
+```
+
+### `pyenv binary save <version> [<output-dir>] [--name <name>]`
+
+Packs an installed version into `<version>-<platform>.tar.gz` (relative paths)
+and writes `<version>-<platform>.meta` describing the build platform (OS, arch,
+distro and libc version) and the system libraries the build links against. Use
+`--name` to set a different base name for both files.
+
+```sh
+pyenv binary save 3.12.7 ./dist
+```
+
+### `pyenv binary generate-installer <metadata-file> --archive-url <url> [-o <output>]`
+
+Reads a `.meta` file and emits a python-build definition. Drop it into
+python-build's definition directory and `pyenv install <name>` installs the
+archive like any other version. The archive location is a parameter, so you can
+host it anywhere (it does not have to be a pyenv location); the archive itself
+must sit next to the `.meta` file so its checksum can be baked into the
+definition.
+
+The definition refuses to install on a different OS/architecture, or an older
+glibc, than the archive was built for, and checks that the system libraries it
+needs are present.
+
+```sh
+pyenv binary generate-installer ./dist/3.12.7-linux-x86_64.meta \
+  --archive-url https://example.com/3.12.7-linux-x86_64.tar.gz \
+  -o "$(pyenv root)/plugins/python-build/share/python-build/3.12.7-linux-x86_64"
+
+pyenv install 3.12.7-linux-x86_64
+```
+
+### `pyenv binary relocate <prefix>`
+
+Rewrites the rpaths of a Python tree unpacked into `<prefix>` so the interpreter
+and its extension modules load the bundled libraries from there rather than from
+the path the archive was built at. Uses `patchelf`. The generated definition
+calls this; you rarely run it by hand.

+# pyenv-link
+A [pyenv](https://github.com/pyenv/pyenv) plugin for linking Python installations and virtual environments into your pyenv root.
+
+This plugin recommends the [pyenv-virtualenv](https://github.com/pyenv/pyenv-virtualenv/) plugin.
+
+## Usage
+
+Make an arbitrary virtualenv available through pyenv. This automatically guesses a fitting name from the prompt, the directory name or the location of the venv.
+
+```console
+$ pyenv link version .venv
+Linked new version named myproject
+```
+
+You can also specify a name to use for the venv.
+
+```console
+$ pyenv link version .venv myname
+Linked new version named myname
+```
+
+The same command can give a platform-specific binary installation a shorter name:
+
+```console
+$ pyenv link version "$(pyenv root)/versions/3.13.14-linux-x86_64" 3.13.14
+Linked new version named 3.13.14
+```
+
+Now you can make pyenv activate/use the venv automatically:
+
+```console
+$ pyenv local myproject
+```

+#### Adding definitions with a Pyenv plugin
+
+You can add your own definitions with a [Pyenv plugin](https://github.com/pyenv/pyenv?tab=readme-ov-file#pyenv-plugins) by placing them under
+`$PYENV_ROOT/plugins/your_plugin_name/share/python-build`.
+
+### Default build configuration
+
+Without the user customizing the build with environment variables (see below),
+`python-build` builds Python with mostly default Configure options
+to maintain the principle of the least surprise.
+
+The exceptions -- non-default options that are set by default -- are listed below:
+
+| Option/Behavior | Rationale |
+|-----------------|-----------|
+| `--enable-shared` is on by default. Pass `--disable-shared` to Configure options to override | The official CPython Docker image uses it. It's required to embed CPython. |
+| argument to `--enable-universalsdk` is ignored and set to `/` | 
+| `--with-universal-archs` defaults to `universal2` on ARM64 architecture | the only dual-architecture Macs in use today are Apple Silicon which can only build that one |
+| argument to `--enable-framework` is ignored and set to a specific value | CPython's build logic requires a very specific argument to avoid installing the `Applications` part globally |
+| argument to `--enable-unicode` in non-MacOS is overridden to `ucs4` for 2.x-3.3 |
+| `MACOSX_DEPLOYMENT_TARGET` defaults to the running MacOS version |
+
+
+#### Integration with 3rd-party package ecosystems
+
+##### Homebrew
+
+Homebrew is used to find dependency packages if `brew` is found on `PATH`:
+* In MacOS, or
+* If the running Pyenv itself is installed with Homebrew
+
+Set `PYTHON_BUILD_USE_HOMEBREW` or `PYTHON_BUILD_SKIP_HOMEBREW` to override this default.
+
+When Homebrew is used, its `include` and `lib` paths are added to compiler search path (the latter is also set as `rpath`),
+and also Python dependencies that are typically keg-only are searched for in the Homebrew installation and added individually.
+
+**NOTE:** Homebrew is not used in Linux by default because it's rolling-release which causes a problem.
+Upgrading a Python dependency in Homebrew to a new major version (that `brew` does without warning)
+would break all Pyenv-managed installations that depend on it.
+You can use a [community plugin `fix-version`](https://github.com/pyenv/pyenv/wiki/Plugins#community-plugins)
+to fix installations in such a case.
+
+##### MacPorts
+
+MacPorts Homebrew is used to find dependency packages if `port` is found on `PATH` in MacOS.
+
+Set `PYTHON_BUILD_USE_MACPORTS` or `PYTHON_BUILD_SKIP_MACPORTS` to override this default.
+
+###### Interaction with Homebrew
+
+If both Homebrew and MacPorts are installed and allowed to be used, Homebrew takes preference.
+There first ecosystem where any of the required dependency packages is found is used.
+
+##### Portage
+
+In FreeBSD, if `pkg` is on PATH, Ports are searched for some dependencies that Configure is known to not search for via `pkg-config`.
+(Later versions of CPython search for more packages via `pkg-config` so this may eventually become redundant.)

-If `--enable-shared` was found in `PYTHON_CONFIGURE_OPTS` or `CONFIGURE_OPTS`,
-`python-build` will automatically set `RPATH` to the pyenv's prefix directory.

+Building CPython with `--enable-optimizations` will result in a faster
+interpreter at the cost of significantly longer build times. Most notably, this
+enables PGO (profile guided optimization). While your mileage may vary, it is
+common for performance improvement from this to be in the ballpark of 30%.
 
 ```sh

+env PYTHON_CONFIGURE_OPTS='--enable-optimizations --with-lto' PYTHON_CFLAGS='-march=native -mtune=native' pyenv install --verbose 3.6.0

+Package mirror URLs are constructed by joining

+
+The rationale is to abstract away difference between directory structures of sites
+of various Python flavors and their occasional changes as well as to accommodate
+people who only wish to cache some select downloads. This also allows to mirror multiple sites at once.
+
+If the mirror being used does not have the same checksum (*e.g.* with a
+pull-through cache like Artifactory), you can set the

+## Contributing
+
+### Testing new python versions
+
+If you are contributing a new python version for python-build,
+you can test the build in a [docker](https://www.docker.com/) container based on Ubuntu 18.04.
+
+With docker installed:
+
+```sh
+docker build -t my_container .
+docker run my_container pyenv install <my_version>
+```
+
+To enter a shell which will allow you to build and then test a python version,
+replace the second line with
+
+```sh
+docker run -it my_container
+```
+
+The container will need to be rebuilt whenever you change the repo,
+but after the first build, this will be very fast,
+as the layer including the build dependencies will be cached.
+
+Changes made inside the container will not be persisted.
+
+To test *all* new versions since a particular revision (e.g. `master`), `cd` to the root of your `pyenv` repo, and run this script:
+
+```sh
+set -e
+set -x
+
+docker build -t pyenv-test-container .
+
+git diff --name-only master \
+  | grep '^plugins/python-build/share/python-build/' \
+  | awk -F '/' '{print $NF}' \
+  | xargs -I _ docker run pyenv-test-container pyenv install _
+```
+
+- Build the docker image with the **t**ag pyenv-test-container
+- Look for the names files changed since revision `master`
+- Filter out any which don't live where python-build keeps its build scripts
+- Look only at the file name (i.e. the python version name)
+- Run a new docker container for each, building that version

+Script to add non-"latest" miniconda releases. Written for python 3.7. Checks
+the miniconda download archives for new versions, then writes a build script
+for any which do not exist locally, saving it to plugins/python-
+build/share/python-build. Ignores releases below 4.3.30. Also ignores sub-
+patch releases if that major.minor.patch already exists, but otherwise, takes
+the latest sub-patch release for given OS/arch. Assumes all miniconda3
+releases < 4.7 default to python 3.6, and anything else 3.7.
+
+optional arguments:
+  -h, --help     show this help message and exit
+  -d, --dry-run  Do not write scripts, just report them to stdout
+  -v, --verbose  Increase verbosity of logging
