  Dynamical Mean Field Theory (DMFT) is a successful method to compute the
electronic structure of strongly correlated materials, especially when it is
combined with density functional theory (DFT). Here, we present an open-source
computational package (and a library) combining DMFT with various DFT codes
interfaced through the Wannier90 package. The correlated subspace is expanded
as a linear combination of Wannier functions introduced in the DMFT approach as
local orbitals. In particular, we provide a library mode for computing the DMFT
density matrix. This library can be linked and then internally called from any
DFT package, assuming that a set of localized orbitals can be generated in the
correlated subspace. The existence of this library allows developers of other
DFT codes to interface with our package and achieve the charge-self-consistency
within DFT+DMFT loops. To test and check our implementation, we computed the
density of states and the band structure of well-known correlated materials,
namely LaNiO3, SrVO3, and NiO. The obtained results are compared to those
obtained from other DFT+DMFT implementations.
