-Description: Provides a SAS interface in R, through 'SASpy'(<https://sassoftware.github.io/saspy/>) and 'reticulate'(<https://rstudio.github.io/reticulate/>).
-  This package helps you create SAS sessions, execute SAS code in remote SAS servers, retrieve execution results and log, and exchange datasets between SAS and R.
-  It also helps you to install 'SASpy' and create a configuration file for the connection. Please review the 'SASpy' license file as instructed so that you comply with its separate and independent license.
