+class Butterflypack(CMakePackage):
+ """ButterflyPACK is a mathematical software for rapidly solving
+ large-scale dense linear systems that exhibit off-diagonal rank-deficiency.
+ These systems arise frequently from boundary element methods, or
+ factorization phases in finite-difference/finite-element methods.
+ ButterflyPACK relies on low-rank or butterfly formats under Hierarchical
+ matrix, HODLR or other hierarchically nested frameworks to compress,
+ factor and solve the linear system in quasi-linear time. The
+ computationally most intensive phase, factorization, is accelerated via
+ randomized linear algebras. The butterfly format, originally inspired by
+ the butterfly data flow in fast Fourier Transform, is a linear algebra tool
+ well-suited for compressing matrices arising from high-frequency wave
+ equations or highly oscillatory integral operators."""
