# This script emulates the bc utility on systems where bc is not
# available. It does not offer the whole bc functionality, only
# that needed by SystemImager master scripts.
#
# bc is an arbitrary precision numeric processing language. The
# utility can be found here: http://www.gnu.org/software/bc/bc.html
