Create task specification list which consists of all the details required to run specific task.

task alias which also serves as unique identifier of the task.
package_spec object
environmental variables to be set in separate process running specific task.
character, indicating the type of package to download and
install. Will be "source" except on Windows and some macOS
builds: see the section on ‘Binary packages’ for those.
an optional character vector of additional option(s) to be passed to
R CMD INSTALL for a source package install. E.g.,
c("--html", "--no-multiarch", "--no-test-load").
Can also be a named list of character vectors to be used as additional options, with names the respective package names.
parameters passed to downstream constructors
Character vector of arguments to pass to R CMD check. Pass each
argument as a single element of this character vector (do not use spaces to
delimit arguments like you would in the shell). For example, to skip
running of examples and tests, use args = c("--no-examples", "--no-tests") and not args = "--no-examples --no-tests". (Note that
instead of the --output option you should use the check_dir argument,
because --output cannot deal with spaces and other special characters on
Windows.)
Character vector of arguments to pass to R CMD build.
Pass each argument as a single element of this character vector (do not use
spaces to delimit arguments like you would in the shell). For example,
build_args = c("--force", "--keep-empty-dirs") is a correct usage and
build_args = "--force --keep-empty-dirs" is incorrect.
character indicating whether the task specification describes check associated with the development (new) or release (old) version of the for which reverse dependency check is run.
