Batch mode
In “batch” mode, cpptraj is executed from the command line with one or more input files containing commands to be processed or STDIN.
The syntax of <input file> is similar to that of ptraj. Keywords specifying different commands are given one per line. Lines beginning with ’#’ are ignored as comments. Lines can also be continued through use of the ’\’ character.
This is the only allowed mode for cpptraj.MPI.
