The input file is read in using CTP, and for convenience, the input parameters
are organized into CTP parameter blocks. Each section describes the variables
in a given parameter block, and then gives an example (from an Fpi (e,e'
)input file). SIMC.FLAGS is an old writeup describing the flags, and contains
some information not included below. Once I've included all of the information
in this section, I'll remove the SIMC.FLAGS.
