utils/move_JDT_PDE_to_dropins.sh

# JDT and PDE are built as update sites.
# The procedure of moving them to dropins is following:
#
# Copy Eclipse installation
# Install JDT or PDE into it
# Copy the difference into dropins
#
# This must go this way to initialize all the plugins.
#
# There is one argument required : a path to a repo that contains JDT and PDE.
#
# Base Eclipse installation is required to not have JDT or PDE installed.
