%description
QEPCAD is an implementation of quantifier elimination by partial
cylindrical algebraic decomposition due originally to Hoon Hong, and
subsequently added on to by many others.  It is an interactive
command-line program written in C/C++, and based on the SACLIB library.
This is QEPCAD B version 1.x, the "B" designating a substantial
departure from the original QEPCAD and distinguishing it from any
development of the original that may proceed in a different direction.
