  This paper presents an implementation of the
Schwerdtfeger-Fillmore-Springer-Cnops construction (SFSCc) along with
illustrations of its usage. SFSCc linearises the linear-fraction action of the
Moebius group in R^n. This has clear advantages in several theoretical and
applied fields including engineering. Our implementation is based on the
Clifford algebra capacities of the GiNaC computer algebra system
(http://www.ginac.de/), which were described in cs.MS/0410044.
  The core of this realisation of SFSCc is done for an arbitrary dimension of
R^n with a metric given by an arbitrary bilinear form. We also present a
subclass for two dimensional cycles (i.e. circles, parabolas and hyperbolas),
which add some 2D specific routines including a visualisation to PostScript
files through the MetaPost (http://www.tug.org/metapost.html) or Asymptote
(http://asymptote.sourceforge.net/) packages.
  This software is the backbone of many results published in math.CV/0512416
and we use its applications their for demonstration. The library can be ported
(with various level of required changes) to other CAS with Clifford algebras
capabilities similar to GiNaC.
