homebrew does internal caching in ARGV that prevents us from doing the
`ARGV.clear; ARGV << 'newarg'` trick twice.
rather than try to further reach in to homebrew's innards, i figure it's
better to just pass multiple arguments down to homebrew code at once,
since it already supports that
refs #47
this delegates to homebrew's uninstall to get its work done. vanilla
`brew uninstall` actually works, but this gives us a more consistent
interface.
as discussed in #47
Jumpcut is a tgz file whose handling isn't currently supported.
This commit adds support for it.
The test for tar.gz and tar.bz are very similar and could probably
be refactored. Leaving that as an exercise for another time.
Should have more use cases before opening that up.
a cheap way to address #17.
i don't really like it, but after a bunch of research and
experimentation to figure out if we can skip `.Trashes` or remove it,
this was the best i could come up with.
I chose Caffeine since it's relatively small to download. Eventually I'd
like to switch this up so we bundle a dmg, zip, etc that the test suite
wires in to verify that we do the Right Thing (tm) with all those file
types. Probably will want to support `file://` URLs in Casks to help us
for that use case.
