# This module implements multiple-clipboards in GPS.
#
# Pressing the keys "alt-e 0" to "alt-e 9" will copy the current
# selection into one of the name clipboards 0 to 9.
# These clipboards can in turn be pasted with "control-t 0" to "control-t 9"
#
# This package is also an example on how to add your on extensions to GPS.
# The keys indicated above are the default keys. These can be overridden at
# the user level through the Edit->Key Shortcuts editor, and will be
# automatically reloaded from one session to the next
#
# This file should be put in the ~/.gps/plug-ins directory, so that
# it is automatically loaded when GPS starts.
#
# By default, only 10 clipboards are provided. By modifying the call to
# parse_xml below, you can create any number of clipboards
