+#!/bin/bash
+#
+# Install specific version of a Homebrew formula
+#
+# Usage: brewv.sh formula_name desired_version
+#
+# Notes:
+# - this will unshallow your brew repo copy. It might take some time the first time
+# you call this script
+# - it will uninstall (instead of unlink) all your other versions of the formula.
+# Proper version management is out of scope of this script. Feel free to improve.
+# - my "git log" uses less by default and when that happens it breaks the script
+# Therefore we have the "--max-count=20" parameter. This might fail to find proper
+# version if the one you wish to install is outside of this count.
