Python 3 bindings for SLEPc libraries

 SLEPc is the Scalable Library for Eigenvalue Problem Computations.
 .
 It is based on PETSc and employs the MPI standard for all
 message-passing communication.
 .
 This is a dummy package that depends on python3-slepc4py-real or
 python3-slepc4py-complex. If both are installed then alternatives can
 be used to set the preferred configuration for slepc4py.
