@ -7,7 +7,7 @@ If a bottle is available and usable it will be downloaded and poured automatical
Bottles will not be used if the user requests it (see above), if the formula requests it (with `pour_bottle?`), if any options are specified on installation (bottles are all compiled with default options), if the bottle is not up to date (e.g. lacking a checksum) or the bottle's `cellar` is not `:any` or equal to the current `HOMEBREW_CELLAR`.
## Bottle Creation
Bottles are currently created using the [Brew Test Bot](Brew-Test-Bot.md). We will be slowly adding them to all formulae.
Bottles are created using the [Brew Test Bot](Brew-Test-Bot.md). This happens mostly when people submit pull requests to Homebrew and the `bottle do` block is updated by maintainers when they `brew pull` the contents of a pull request. For the Homebrew organisations' taps they are uploaded to and downloaded from [Bintray](https://bintray.com/homebrew).
By default, bottles will be built for the oldest CPU supported by the OS/architecture you're building for. (That's Core 2 for 64-bit OSs, Core for 32-bit.) This ensures that bottles are compatible with all computers you might distribute them to. If you *really* want your bottles to be optimized for something else, you can pass the `--bottle-arch=` option to build for another architecture - for example, `brew install foo --bottle-arch=penryn`. Just remember that if you build for a newer architecture some of your users might get binaries they can't run and that would be sad!
