Here is a list of all modules with brief descriptions:

Mm_boundary_conditions	The purpose of the module is to apply noncharacteristic and processor boundary condiitons
Mm_compile_specific	This module contains subroutines that are compiler specific
Mm_constants
Mm_data_input	This module features procedures, which for a specific time-step, read in the raw simulation data for the grid and the conservative variables and fill out their buffer regions
Mm_data_output	This module enables the restructuring of the raw simulation data file(s) into formatted database file(s). The formats that may be chosen from include Silo-HDF5 and Binary. Each of these database structures contains information about the grid as well as each of the flow variable(s) that were chosen by the user to be included
Mm_delay_file_access
Mm_derived_variables	This module features subroutines that allow for the derivation of numerous flow variables from the conservative and primitive ones. Currently, the available derived variables include the unadvected volume fraction, specific heat ratio, liquid stiffness, speed of sound, vorticity and the numerical Schlieren function
Mm_eigen_solver	The purpose of the module is to solve an eigenvalue problem for a complex general matrix. Subroutines are imported from EISPACK (https://netlib.org/eispack/) with minor modifications for compatibility
Mm_finite_differences
Mm_global_parameters	This module contains all of the parameters characterizing the computational domain, simulation algorithm, stiffened equation of state and finally, the formatted database file(s) structure
Mm_helper_basic
Mm_mpi_proxy	This module serves as a proxy to the parameters and subroutines available in the MPI implementation's MPI module. Specifically, the role of the proxy is to harness basic MPI commands into more complex procedures as to achieve the required communication goals for the post-process
Mm_nvtx
Mm_precision_select	This file contains the definition of floating point used in MFC
Mm_start_up	This module contains the subroutines that read in and check the consistency of the user provided inputs. This module also allocates, initializes and deallocates the relevant variables and sets up the time stepping, MPI decomposition and I/O procedures
