`model`	model name from model library
`code`	C++ code specifying ODE system
`pk_code`	C++ code called at any event
`dose_code`	C++ code called at dose event only
`file`	file containing C++ code
`func`	R function to be used with deSolve library
`state_init`	vector of state init
`parameters`	list or vector of parameter values
`units`	list or vector of parameter units
`size`	size of state vector for model. Size will be extracted automatically from supplied code, use this argument to override.
`lagtime`	lag time
`obs`	list with "scale": character string with definition for scale, e.g. "V" or "V*(WT/70)". If NULL, scale defaults to 1., and "cmt" the observation compartment
`dose`	specify default dose compartment, e.g. list(cmt = 1)
`covariates`	specify covariates, either as a character vector or a list. if specified as list, it allows use of timevarying covariates (see 'new_covariate()' function for more info)
`declare_variables`	declare variables
`iiv`	inter-individual variability, can optionally be added to library
`iov`	inter-occasion variability, can optionally be added to library
`omega_matrix`	variance-covariance matrix for inter-individual variability, can optionally be added to library
`ruv`	residual variability, can optionally be added to library
`default_parameters`	population or specific patient values, can optionally be added to library
`cpp_show_code`	show generated C++ code
`package`	package name when saving as package
`install`	install package after compilation?
`folder`	base folder name to create package in
`lib_location`	install into folder ('–library' argument)
`verbose`	show more output
`as_is`	use C-code as-is, don't substitute line-endings or shift indices
