			Ipp is a Perl script for facilitating the creation of a complicated
			file (say, a lammps input file or tools/createatoms input file) using
			a template file.

			ipp was created and is maintained by Reese Jones (Sandia), rjones at
			sandia.gov.

			Example 1:

			If one has a template for a long lammps input file called
			"template_lammps.input" where a few parameters need to be changed. One
			can define these parameters in a short file called
			"fill_parameters_lammps.input" and execute "ipp -p
			fill_parameters_lammps.input template_lammps.input >
			lammps.input". The file "lammps.input" file will be the final lammps
			input file.

			Example 2:

			If one has a template for a long createAtoms input file called
			"template_createAtoms.input" that creates double elpasolite
			crystals. One wants to change the lattice constants and tilting angle
			of the octahedrons. One can define these parameters in a short file
			called "fill_parameters_createAtoms.input" and execute "ipp -p
			fill_parameters_createAtoms.input template_createAtoms.input >
			createAtoms.input". The "createAtoms.input" file will be the final
			createAtoms input file. If one has an excetable for createAtoms called
			"create", one can simply execute "create<createAtoms.input" to create
			the crystal that LAMMPS can read.
