JDFTx  1.7.0
Create a VASP CHGCAR file from a JDFTx output file. Usage:

    createVASP <jdftxOutFile> <vaspFile> [<nFilename>] [<Ninterp>=1]

Save the final structure and electron density from JDFTx output
file <jdftxOutFile> to a VASP CHGCAR format file in <vaspFile>.
The electron density is read from the appropriate filename
determined by parsing the output; this can be overriden by
explicitly specifying <nFilename>.

Optional <Ninterp> specifies a grid multiplier for Fourier interpolation.

Note: this tool requires awk and octave to be available in path.
