# Set of bash functions that allows you to bookmark folders in the command-line.
# To bookmark a folder, simply go to that folder, then bookmark it like so:
#   bookmark foo
#
# The bookmark will be named "foo"
#
# When you want to get back to that folder use:
#   go foo
#
# To see a list of bookmarks:
#   bookmarksshow
#
# Tab completion works, to go to the shoobie bookmark:
#   go sho[tab]
#
# Your bookmarks are stored in the ~/.bookmarks file
