vswitch.sh

#!/bin/sh

##
# Simple "git branch switcher" that uses the included "dmenu.sh" script to pop
# up a menu to switch between branches.
#
# It has a few neat tricks, such as "vswitch ...partial..." will limit the
# popup menu to only branches containing that term, and if there is only one
# term that contains that partial term it won't bother showing the menu.
#
#  vswitch.sh      => full menu
#  vswitch.sh bug  => will popup any branches with the word "bug" in them
#  vswitch.sh mast => will likely switch you directly to the master branch
#
