#' Rscript output.R [options]
#'
#' [options] can be the following flags:
#'
#' --help, -h: show this help text and exit
#' --test, -t: tests output.R without actually starting any run
#' --renv=<path> load the renv located at <path>, incompatible with --update
#' --update update packages in renv first, incompatible with --renv=<path>
#'
#' [options] can also specify the following variables. If they are not specified
#' but needed, the scripts will ask the user.
#'
#' comp= comp=single means output for single runs (reporting, …)
#' comp=comparison means scripts to compare runs (compareScenarios2, …)
#' comp=export means scripts to export runs (xlsx_IIASA, …)
#' filename_prefix= string to be added to filenames by some output scripts
#' (compareScenarios, xlsx_IIASA)
#' output= output=compareScenarios2 directly selects the specific script
#' outputdir= Can be used to specify the output directories to be used.
#' Example: outputdir=./output/SSP2-Base-rem-1,./output/NDC-rem-1
#' remind_dir= path to remind or output folder(s) where runs can be found.
#' Defaults to ./output but can also be used to specify multiple
#' folders, comma-separated, such as remind_dir=.,../otherremind
#' slurmConfig= use slurmConfig=priority, short or standby to specify slurm
#' selection. You may also pass complicated arguments such as
#' slurmConfig='--qos=priority --mem=8000'
