 Moltemplate is a general cross-platform text-based molecule builder for LAMMPS,
 an extremely flexible and customizable molecular dynamics engine.
 
 Moltemplate was designed for inventing new kinds of complex coarse-grained toy
 models of molecules, molecular machines, and assemblies. However it is well
 suited for preparing realistic all-atom simulations as well. It supports a wide
 variety of existing force fields and models including: OPLS, AMBER(GAFF,GAFF2),
 COMPASS, LOPLS(2015), EFF, TraPPE(1998), MOLC, mW, ELBA(water), and oxDNA2.
 However it can be used to build molecules using any of the force fields (and
 atom styles) available in LAMMPS, including new force fields created by
 modifying the LAMMPS source code. Molecules can be copied, combined, and linked
 together as building-blocks to define new molecules (hierarchically). Once
 built, individual molecules and subunits can be customized (atoms, bonds, and
 subunits can be moved and deleted). Moltemplate is currently interoperable with:
 VMD , PACKMOL , OVITO , CellPACK , VIPSTER , and the ATB molecule server
 (by using the ltemplify.py converter).
