Max Howell	19e387d92e	brew upgrade ... Consequence: you can no longer install when something is already installed, you must upgrade it. This doesn't apply if the formula in question was unlinked. You can still --force installs though. Rationale: the old way of installing over the top would leave symlinks to multiple versions in /usr/local if the old version had a file the newer version didn't. The new upgrade command handles everything properly.	2011-08-24 22:30:43 +01:00
Max Howell	ec9cbc6466	Optimise/simplify brew help ... Be more useful by being more concise. I referenced dozens of other mature commands’ usage to figure out what to do here. Also separated out the help into its own command for consistency.	2011-03-13 12:54:30 +00:00
