DESCRIPTION:

Eccet is a three dimensional volume segmentation and rendering
system. Some operators work along a given axis of the volume.
Whereever you can specify an axis, this can be done using either
the characters x,y,z (or X,Y,Z) or numerically using 0,1,2.
Note, that due to historical reasons, some commands might only
take the numeric versions. This is a bug. Please notify us, if
this happens to you.
