	# top of this, there are a ton of files that need to be merged
	# so instead of specifying all these files, we're instead
	# removing all the extra fluff from the source tree and then
	# merging it all over when we're done.

	# This ebuild will compile eclipse for gtk2, motif, and kde
	# toolkits depending on the use flags set.  If all are set, the
	# default version linked to is the GTK2 version.  When building
	# for KDE though, the motif version must be built with support
	# for KDE.  Apparently the motif build also supports KDE when
	# this is done - I could be wrong though.
