-# usage: tap <command> {options} [args]
 #
-# Launches a tap command.
+# Runs tapexe, first setting the default ENV variables expected
+# by tap when installed by RubyGems.  Splitting the work into
+# two files like this is a pattern allowing tapexe to be run
+# without RubyGems or the default ENV (ie 'ruby tapexe').
 #
-# examples:
-#   tap generate root .                  # generates a root dir
-#   tap run taskname --option input      # runs the 'taskname' task
-#
-# help:
-#   tap --help                           # prints this help
-#   tap command --help                   # prints help for 'command'
