    Environment

    Commentary:
        - Sets machine environment variables if they don't exist
        - Prepends to *PATH if it already has a value

    Actions:
        1. Enforces python to use utf-8 encoding (for python 2)
        2. Prevent python from writing out pyc files
        3. Sets the default shell to gitbash
        4. Puts rez executables on PATH
        5. Puts rez python on PYTHONPATH

    Manual Steps
        1. completion script can be symlinked to the home dir from C:\Users\jsparrow\src\rez_venv\src\rez\src\rez\completion
            bash -c -l "ln -s /c/Users/jsparrow/src/rez_venv/src/rez/src/rez/completion/completion /c/rez/completion"
        2. rezconfig.py needs to be edited here: c:\users\jsparrow\src\rez_venv\src\rez\src\rez\rezconfig.py
            - change platform_map value to

                platform_map = {
                    "os": {
                        r"windows-(\d+)(\..*)": r"Windows-\1"
                    },
                    "arch": {
                        "AMD64": "x86_64",
                    },
                }

        3. rez bind os to automatically bind arch, os, and platform
            - rez bind os
            - rez bind -r os

    Next Steps
        1. Update to the latest rez from git
        2. Rez Changes
            - See if the following changes are still relevant
            - rez/resolved_context.py

                executor_path = executor.env.PATH.value()
                executor_path = re.sub(r'([a-zA-Z]):\\', r'/\g<1>/', executor_path)
                executor_path = executor_path.replace('\\', '/')
                executor_path = executor_path.replace(';', ':')
                executor.env.PATH = executor_path

# Install
#
#    Manual Steps
#        1. Edit install.py
#           - Insert "-e," into `run_command([py_executable, "m", "pip", "install", "-e", "."])`
#        2. python rez/install.py -v /c/rez
#        3. completion script can be symlinked to the home dir from C:/Users/%USERNAME%/src/rez_venv/src/rez/src/rez/completion
#            - `bash -c -l "ln -s /c/Users/%USERNAME%/src/rez_venv/src/rez/src/rez/completion/completion /c/rez/completion"`
#        4. If not using Method bootstrap, rezconfig.py needs to be edited here: c:/users/%USERNAME%/src/rez_venv/src/rez/src/rez/rezconfig.py
#            - change platform_map value to
#
#                platform_map = {
#                    "os": {
#                        r"windows-(/d+)(/..*)": r"Windows-/1"

#                    },
#                }
#
#        5. rez bind os to automatically bind arch, os, and platform
