#' @title A Swiss-Army Knife for Data I/O
#' @description The aim of rio is to make data file input and output as easy as possible. \code{\link{export}} and \code{\link{import}} serve as a Swiss-army knife for painless data I/O for data from almost any file format by inferring the data structure from the file extension, natively reading web-based data sources, setting reasonable defaults for import and export, and relying on efficient data import and export packages. An additional convenience function, \code{\link{convert}}, provides a simple method for converting between file types.
#' 
#' Note that some of rio's functionality is provided by \sQuote{Suggests} dependendencies, meaning they are not installed by default. Use \code{\link{install_formats}} to make sure these packages are available for use.

#' # export
#' library("datasets")
#' export(mtcars, csv_file <- tempfile(fileext = ".csv")) # comma-separated values
#' export(mtcars, rds_file <- tempfile(fileext = ".rds")) # R serialized
#' export(mtcars, sav_file <- tempfile(fileext = ".sav")) # SPSS

#' # import
#' x <- import(csv_file)
#' y <- import(rds_file)
#' z <- import(sav_file)

#' # convert sav (SPSS) to dta (Stata)
#' convert(sav_file, dta_file <- tempfile(fileext = ".dta"))
