Sets ISPP directives at the top of an ISS.

directives_section(app_name, include_R = FALSE,
  R_version = paste0(R.version$major, ".", R.version$minor),
  include_Pandoc = FALSE, Pandoc_version = rmarkdown::pandoc_version(),
  include_Chrome = FALSE, include_Rtools = FALSE,
  Rtools_version = "3.5", app_version = "0.0.0", publisher = "",
  main_url = "", custom_vars = "", custom_values = "")

`app_name`	The name of the app. It will be displayed throughout the installer's window titles, wizard pages, and dialog boxes. See [Setup]:AppName for details. For continuous installations, `app_name` is used to check for an R package of the same name, and update it. The Continuous Installation vignette has more details.
`include_R`	To include R in the installer, `include_R = TRUE`. The version of R specified by `R_version` is used. The installer will check each user's registry and only install R if necessary.
`R_version`	R version to use. Supports inequalities. Defaults to: `paste0(">=", R.version$major, '.', R.version$minor)`.
`include_Pandoc`	To include Pandoc in the installer, `include_Pandoc = TRUE`. If installing a flexdashboard app, some users may need a copy of Pandoc. The installer will check the user's registry for the version of Pandoc specified in `Pandoc_version` and only install it if necessary.
`Pandoc_version`	Pandoc version to use, defaults to: pandoc_available.
`include_Chrome`	To include Chrome in the installer, `include_Chrome = TRUE`. If you would like to use Chrome's app mode, it is no longer supported by Google :(.
`include_Rtools`	To include Rtools in the installer, `include_Rtools = TRUE`. For some packages to build properly, you may need to include Rtools.
`Rtools_version`	Rtools version to include. For more information, see Building R for Windows.
`app_version`	Version number of the app being installed, defaults to `'0.0.0'`. It is displayed in the Version field of the app's Add/Remove Programs entry. See [Setup]:AppVersion for details.
`publisher`	String displayed on the "Support" dialogue of the Add/Remove Programs Control Panel applet, defaults to " ". See [Setup]:AppPublisher for details.
`main_url`	String. Defaults to "".
`custom_vars`	String vector. Defaults to "", and must be the same length as `custom_values`.
`custom_values`	String vector of values for `custom_vars`. Defaults to "", and must be the same length as `custom_vars`.

ISPP directives automate compile-time tasks and decrease the probability of typos. When referring to an ISPP directive, use '{#var_name}'. For more information, call ispp_doc() or visit ISPP Help.

custom_vars and custom_values utilize the #define directive.

Chainable character vector, which can be used as the text argument of writeLines to generate an ISS.
