# Purpose: manage LAMMPS packages, external libraries, and builds
# create a version of LAMMPS specific to an input script(s)
# Syntax: Make.py switch args ...

# hi-level tasks that can be performed:
# install/uninstall packages and build the associated external libs
# use -p and -u and -e
# install packages needed for input script(s)
# use -i and -p
# create new dir with only the source code needed for input script(s)
# use -i and -n
# build LAMMPS, either in src or new dir
# use -b
# data structures:
# packstd list = ["COLLOID", "GPU", ...]
# packuser list = ["USER-SPH", "USER-EWALDN", ...]
# cfiles,hfiles dicts of LAMMPS *.cpp,*.h files =
# {"fix_nve.cpp": "", "angle_diplole.cpp": "USER-MISC", ...}
# cdep,hdep dicts of files with list of LAMMPS *.h files they include =
# {"fix_nve.cpp": ['fix_nve.h', 'atom.h', 'force.h', ...'], ...}
# creq,hreq lists of src files needed to build LAMMPS for input scripts =
# ["main.cpp", "atom.cpp", ...]
# ISSUES:
# see KLUDGE comments
# add more general input script parsing, see NOTE comments
# including another file
# variable substitution could be used to create new command (hard)
# single/double quotes could affect args and hide nested commands
# hybrid styles can have required sub-styles
# if-then-else and run every could nest other commands as args
# special case: linalg sometimes needed with ATC external lib
# could scan atc/Makefile.lammps for it
# can long makes print incrementally to screen as they progress?
# add a verbose output option?
