  <summary>Explanation of variables</summary>

- `$(BUILD_SERVER)` : the server the main builder is using to build a tor-browser release
- `$(STAGING_SERVER)` : the server the signer is using to to run the signing process
- `$(TOR_LAUNCHER_VERSION)` : version of `tor-launcher`, used in tags
    - example : `0.2.33`
- `$(ESR_VERSION)` : the Mozilla defined ESR version, used in various places for building tor-browser tags, labels, etc
    - example : `91.6.0`
- `$(ESR_TAG)` : the Mozilla defined hg (Mercurial) tag associated with `$(ESR_VERSION)`
    - exmaple : `FIREFOX_91_7_0esr_BUILD2`
- `$(ESR_TAG_PREV)` : the Mozilla defined hg (Mercurial) tag associated with the previous ESR version when rebasing (ie, the ESR version we are rebasing from)
- `$(RR_VERSION)` : the Mozilla defined 'Rapid Relese' version, used in various places for building geckoview tags, labels, etc
    - example : `96.0.3`
- `$(RR_TAG)` : the Mozilla defined hg (Mercurial) tag associated with `$(ESR_VERSION)`
    - exmaple : `FIREFOX_96_0_3_RELEASE`
- `$(RR_TAG_PREV)` : the Mozilla defined hg (Mercurial) tag associated with the previous ESR version when rebasing (ie, the ESR version we are rebasing from)
- `$(TOR_BROWSER_MAJOR)` : the Tor Browser major version
    - example : `11`
- `$(TOR_BROWSER_MINOR)` : the Tor Browser minor version
    - example : either `0` or `5`; Alpha's is always `(Stable + 5) % 10`
- `$(BUILD_N)` : a project's build revision within a its branch; this is separate from the `$(TOR_BROWSER_BUILD_N)` value; many of the Firefox-related projects have a `$(BUILD_N)` suffix and may differ between projects even when they contribute to the same build.
    - example : `build1`
- `$(TOR_BROWSER_BUILD_N)` : the tor-browser build revision for a given Tor Browser release; used in tagging git commits
    - example : `build2`
    - **NOTE** : A project's `$(BUILD_N)` and `$(TOR_BROWSER_BUILD_N)` may be the same, but it is possible for them to diverge. For example :
        - if we have multiple Tor Browser releases on a given ESR branch the two will become out of sync as the `$(BUILD_N)` value will increase, while the `$(TOR_BROWSER_BUILD_N)` value may stay at `build1` (but the `$(TOR_BROWSER_VERSION)` will increase)
        - if we have build failures unrelated to `tor-browser`, the `$(TOR_BROWSER_BUILD_N)` value will increase while the `$(BUILD_N)` will stay the same.
- `$(TOR_BROWSER_VERSION)` : the published Tor Browser version
    - example : `11.5a6`, `11.0.7`
- `$(TOR_BROWSER_BRANCH)` : the full name of tor-browser branch
    - typically of the form: `tor-browser-$(ESR_VERSION)esr-$(TOR_BROWSER_MAJOR).$(TOR-BROWSER_MINOR)-1`
- `$(TOR_BROWSER_BRANCH_PREV)` : the full name of the previous tor-browser branch (when rebasing)
- `$(GECKOVIEW_BRANCH)` : the full name of geckoview branch
    - typically of the form: `tor-browser-$(RR_VERSION)-$(TOR_BROWSER_MAJOR).$(TOR-BROWSER_MINOR)-1`
- `$(GECKOVIEW_BRANCH_PREV)` : the full name of the previous geckoview branch (when rebasing)
