Nature of problem:
Analysis of the molecular electron density and density deformations, including fast evaluation of electrostatic potential, electric field and Hellmann-Feynman forces on nuclei.

Solution method:
The method of Deformed Atoms in Molecules, reported elsewhere[1], is used for partitioning the molecular electron density into atomic fragments, which are further expanded in spherical harmonics times radial factors. The partition is used for defining molecular density deformations and for the fast calculation of several properties associated to density.

Density must come from a LCAO calculation (any level) with spheri- cal (not Cartesian) Slater or Gaussian functions.

Unusual features:
The program contains an OPEN statement to binary files (stream) in several files. This statement has not a standard syntax in Fortran 90. Two possibilities are considered in conditional compilation: Intel's ifort and Fortran2003 standard. This latter is applied to compilers other than ifort (gfortran uses this one, for instance).

Additional comments:
Quick-start guide and User's manual in PDF format included in the package. User's manual is also accessible from the Graphical User Interface.

Running time:
Largely dependent on the system size and the module run (from fractions of a second to hours).
