These were being picked up as just "#{prefix}/lib" and prefix+'lib' due
to the eagerness of the regex. Reordering "lib" and "libexec" will take
care of it; I couldn't think of a more clever solution.

These are external commands---documentation has been moved to the wiki.

Commit dec4b73aa0 ("Allow `brew update --rebase`") changed the format of
the `git pull` command slightly, introducing an extra space (to allow
for the --rebase option), so let's update the test expectations for this.

We still need to write tests for '--rebase', but in the meantime they
once again pass for the normal case.

Commit 2695821e98 ("Only use the bottle if its version is up-to-date")
essentially broke the ImageMagick bottle, because the version parsing
logic returns "1" as the bottle version.

Fixing this requires only a slight modification to the bottle URL regex;
includes a test.

A few formula use ARGV.flag? instead of ARGV.include?. This made `audit`
recognize a few undocumented instances of a '--devel' option, but we can
just ignore that like '--HEAD' for now, and change the behavior if we
decide they need to be documented explicitly in each formula.

To assist those new to stuff.

So that the cache directory will get created if the user runs `brew fetch`
instead of `brew install` as the first command.

This is consistent with how other options are displayed.

Also adjust output text slightly for prettiness.

A possibly useful side effect here is safe_system has a defined Exception (subclassing RuntimeError) now.

This reverts commit af8e3b5aeacdb10a412560e131d631ba733a8346.

`brew mirror-check <formula...>` will process a list of Formulae and check
their mirrors to see if they are reachable and the MD5 sums are valid.

Mirrors can now be declared using the `mirror` method which works similar to
`depends_on` and takes the same arguments as `url`.

The formula class now has a public `fetch` method that cycles through the
mirror list if the downloader for the primary URL throws a `DownloadError`.
Other brew commands, like brew-fetch, also benefit from mirror support by using
this method.

Closes Homebrew/homebrew#7574.

`DownloadError` is an exception that download stratigies can throw to indicate
that a fetch was incomplete due to a failure in communication.

The `curl` method in `utils.rb` has been upgraded to throw a `DownloadError` if
something bad happens to `curl` execution.

Commit 00cd16f changed oudated_brews to return a list of Formula
objects rather than a list of lists containing formula information.

Now we must access the formula name by using the 'name' accessor rather
than an array index.

Fixes Homebrew/homebrew#7528.
Closes Homebrew/homebrew#7572.

Previously, `outdated_brews` returned a list of lists---each containing three
components of a Formula object:

  - f.rack
  - f.name
  - f.version

Frequently more information is required which necessitates back-casting from
`name` to a Formula object---simpy returning formula objects removes this step.

`rack` is a commonly used alias for `formula.prefix.parent`---so common that it
gets defined and used quite a bit. This patch makes `rack` an official method
of the `Formula` class.

Refs Homebrew/homebrew#5188.

When installing with --HEAD, cached repo clones do "git fetch origin"
followed by "git reset --hard". This will only reset the working tree
and index to the state of the local HEAD, but Homebrew will think it's
updated and install anyway. "git reset --hard origin/master" will
achieve the desired result.

Should fix Homebrew/homebrew#7613.

Otherwise, for formula that making the very first install into `sbin`, the
following line will fail with a critical error:

    bin = (HOMEBREW_PREFIX/bin.basename).realpath.to_s

Because `sbin` will not exist until after `link` runs.

This isn't very clean as it moves `check_PATH` away from the other checks in
`caveats`, but I couldn't think of a better hotfix that did not require a bit
of code shuffling and re-writing.

`brew-unpack` now runs `Formula.brew` and copies the stage directory to the
unpack location. This provides two improvements:

  - Patches may be applied. The `patch` metho of the Formula class is
    overloaded such that patches are only applied if the `--patch` option is
    passed to `brew unpack`.

  - Formula can respond better to flags passed by `ARGV`.

Some trickery is pulled to ensure `DATA` is correctly set for each unpacked
formula.

`brew options --installed` will print options for formulae that are
already installed.
