	to be set to $CINTSYSDIR)
	cintversion should be: 6.1.19 (the earlier 6.1.12 did not work!)
	container implements now the margins and cleft, cwidth, etc dimension,
	in a coherent manner

[0.9.28]
	Check the presence of glib-config as well, separately from gts-config

[0.9.27]

	the current frame


[0.9.24]
	margins removed from frame, and implemented in container; many changes related to
	this!!!

	isolines2 drawstyle using gts library

[0.9.15]
	tic calculation improved: a tic at theoretical 0 (but represented by
	some value like 1.734e-18) will now be shown as 0
	upper limit for tics is extended by a tiny-bit to tolerate floating-point
	imprecisions

[0.9.14]
	operator%(function,function) introduced
	jpg terminal added

[0.9.13]

	floor() function added
	permanent attribute introduced for plottable

[0.9.11]

	introduced to easily set transformed axes

	Number of tics is limited to 50 to avoid problems arising from bad settings

	The global functions _1, _2, etc are initialized now more correctly

[0.9.9]
	replot_request class is returned by many set:: functions, upon which
	G__ateval will make a replot in interactive mode (for example set::grid(true)
	will cause an automatic replot)

	an title_autoset flag is implemented in axis. if user sets title, this is set to
	false, and the automatic title setting by dgraph will not have an effect

	debian package files are created in debian/package-files

	arc::draw functions implemented, but only 'rx' of the two different radii (rx and ry)
	has any effect, and it will be a circle anyway. 

	Documentation of mframe has the standard format

	changelog is copied to the documentation directory during install
	available via 'blop -h changelog' or 'blop -h version'

[0.9.1]
