+ branch by just looking at what branch you have checked out locally, so make

+ change the version number because it uses that in naming the tarballs it
+ creates.
+ 
+-Next, make sure you have Docker installed.
+-
+-**TODO: Fix the release script to pull sympy/sympy-release from Dockerhub.**
++If you want to test the release process without pushing a branch to the
++official repo, you can push a branch to your fork and use `fab vagrant
++release:fork='username'`, where `username` is your GitHub username.  Note that
++once you do the actual release, you should do it in a branch in the official
++GitHub repo. **NOTE**: If your fork does not have all the tags of the
++official repo, then the code that finds the previous version will not work
++correctly.  Hence, you may see things like more authors in the authors list
++than you should.  To remedy this, be sure to do `git fetch origin --tags` and
++`git push github --tags`.
+ 
+ Once you have done these things, execute:
+ 
+-    ./release.sh <BRANCH> <VERSION>
++    fab vagrant release
+ 
+-where `<BRANCH>` is the release branch (e.g., `0.7.3`), and `<VERSION>` is the
+-release version (e.g., `0.7.3rc1`).
++this create release tarballs and put them all into a new "release" directory
++of the current directory.
+ 
+-On Linux, you may need to use `sudo` to execute this.
++# Testing things
+ 
+-This will run all the release scripts. If they are successful, they will
+-create release tarballs and put them all into a new "release-VERSION"
+-directory of the current directory. Most likely they will fail the first time,
+-in which case you will need to investigate why and fix things (e.g., update
+-authors, run tests, update whitelists in `rever.xsh`, fix setup.py). The whole
+-script can take about an hour or so to run (depending on how long the tests
+-take). Every time you re-run the script, it pulls from the branch and runs
+-everything from scratch.
++The full test suite is not run by fabric, because we leave that to
++Travis. However, there are things that need to be tested specific to the
++release. Most of these things are done automatically by the release command
++(like testing that the tarball can be installed), but one thing must be tested
++manually, because it has to be inspected by hand, namely, making sure that the
++tarballs contain everything, and don't contain any junk files.
+ 
+-At the end it will print two things, the list of authors, and the md5 sums.
+-Copy the list of authors into the release notes. You should verify that the
+-md5 sums of the release files are the same as what are printed.
++Run
++
++    fab vagrant show_files:arg
++
++to show the files in the tarball, where `arg` is `source` or `html`.  You'll
++probably want to pipe the output of this into `less`, so that you can inspect
++it.
++
++You should also open the pdf and make sure that it has built correctly, and
++open the html docs and make sure that they have built correctly.

++# Doctest Collection Issue Fix Documentation
++
++## Issue Summary
++There was an issue in the pytest codebase where running `pytest --doctest-modules __init__.py` would only collect a single doctest from the `__init__.py` file. This was due to a special case handling in the `main.py` file that prematurely stopped the collection process after the first doctest was collected.
++
++## Changes Made
++The special case handling logic was located in `main.py` between lines 768-781. The code was designed to yield only the first item from the collection of the `__init__.py` module, which caused the issue.
++
++The following changes were made to `main.py`:
++- Removed the conditional check for `argpath.basename == "__init__.py"`.
++- Removed the logic that yielded only the first collected item and returned.
++- Ensured that `yield from matching` is the only line that executes for any Python module file, allowing all doctests to be collected.
++
++## Testing Process
++To test the changes, a doctest was added to an existing `__init__.py` file within the `testing/example_scripts/collect/package_init_given_as_arg/pkg/` directory. The pytest command was then run with the `--doctest-modules` option to ensure that the doctest was collected and executed.
++
++## Test Results
++The test results confirmed that the issue was resolved:
++- The pytest command collected 2 items, including the doctest in `__init__.py`.
++- The doctest added for testing purposes passed successfully.
++
++## Conclusion
++The doctest collection issue in `__init__.py` files has been successfully resolved with the changes made to the `main.py` file. The pytest framework should now correctly collect all doctests from `__init__.py` files when the `--doctest-modules` option is used.

+-        X : set of x_i's in order, it can be a list or a Matrix
+-
+-        Both ``self`` and X can be a row or a column matrix in any order
+-        (i.e., jacobian() should always work).
