########################################################################

# Remark: Sept. 2006, M. Spiekermann
#
# Here we build first a parser called spec parser which translates the
# algebra's spec-files int flex and bison specifications which are needed
# to define and build the secondo parser. This is the parser which translates
# secondo commands of the executable level into nested list syntax which will
# then be processed by the SecondoInterface::Secondo().
