libdlr is a library providing Fortran subroutines to build and work with the
discrete Lehmann representation (DLR) of single particle imaginary time Green's functions,
as well as a stand-alone Python module pydlr implementing the same functionality.
For more information see the documentation, and the references below.
For a C++ implementation of the DLR, please see cppdlr. For a Julia implementation, see Lehmann.jl.
